A statistical approach to predict flexural strength and flame retardation properties for natural fibre/ epoxy composites

This research investigates the development of a mathematical model to predict the influence of flame retardants (FR) on the mechanical and flame retardancy performance of natural fibre reinforced thermosetting composites. The study focuses on two types of FRs: Diammonium Phosphate (DAP) and silica fumes that were added to Jute reinforced epoxy composites (JRECs). Two mathematical models were established based on three variables and two measured responses. The variables include FRs type, FR content, and FR method of preparation, while the measured responses are Limiting oxygen index (LOI) and Flexural strength (FS). The models were developed using a statistical approach based on multiple linear regression fitting and validated using analysis of variance (ANOVA) technique. The developed models were verified using experimental result data from literature and the analysis of these models showed that the maximum discrepancy between the observed and predicted values for relative LOI and relative FS was within the range of [Formula: see text] 6% and [Formula: see text] 5%, respectively. This research contributes to the understanding of the impact of FRs on the mechanical and flame retardancy performance of natural fibre reinforced thermosetting composites, which can aid in the design and development of safer and more efficient composite materials.

Eco-friendly flame retardant comprising chitosan-based effectively enhances the flame retardancy of wood with low weight percent gain

Nowadays, there are many types of flame retardants, whether halogenated or halogen-free, that can improve the flame retardancy of wood. However, they continue to pose a significant threat to our environment and cause a substantial increase in the weight gain rates after treatment. It is highly desirable yet challenging to develop an eco-friendly and efficient flame retardant with low weight gain rates. Here, we report a simple and fast process for making eco-friendly flame retardants (chitosan, gelatin, sodium phytate and clay) with weight gain rates of 3.7 %, which form excellent flame retardancy systems. This method can be used to create a 53.5 % reduction in peak heat release rate (pHRR) an 189 % increase in ignition time (cone colorimeter), and a 71.9 % reduction in peak temperature (alcohol spray lamps) compared to raw wood. The results displayed that the effect of flame retardancy (Decreased ratio for pHRR/Weight percent gain) was the best in the past three years. In addition, the flame retardancy mechanism is thoroughly analyzed using the techniques of Raman and so on. This study proposes a novel strategy featured by eco-friendly and simple preparation process for enhancing the flame retardancy of wood in important areas.

OPTIMIZING THE AMOUNT OF FLAME RETARDANT USED FOR SPRUCE WOOD

The study investigated the effect of the amount of selected retardant coatings produced and used in the Slovak Republic on the fire resistance of spruce wood samples. Experiments were conducted for two different types of flame retardants: intumescent flame retardant (IFR) and inorganic salt-based flame retardant (IS). Based on different amounts of coating applied to spruce wood samples, the important parameters as mass loss, mass loss rate and fire spread rate were determined. The experiment consisted of applying a flame source to the samples at an angle of 45° and monitoring the mass of the samples during the experiment. The findings show that when IFR is used, the protection effect of the wooden samples increases linearly with the amount of coating. However, for the samples on which an IS flame retardant was applied, a higher amount of coating had no effect on increasing the fire resistance of the wood. In this case, the average total mass loss was the same regardless of the amount of coating, yet a significant retardation effect was observed compared to the untreated samples. Samples treated with IFR showed a lower total mass loss and also a significantly lower maximum mass loss rate compared to the samples with applied IS flame retardant.

Recent Advances in Fire-Retardant Silicone Rubber Composites.

Silicone rubber (SR), as one kind of highly valuable rubber material, has been widely used in many fields, e.g., construction, transportation, the electronics industry, automobiles, aviation, and biology, owing to its attractive properties, including high- and low-temperature resistance, weathering resistance, chemical stability, and electrical isolation, as well as transparency. Unfortunately, the inherent flammability of SR largely restricts its practical application in many fields that have high standard requirements for flame retardancy. Throughout the last decade, a series of flame-retardant strategies have been adopted which enhance the flame retardancy of SR and even enhance its other key properties, such as mechanical properties and thermal stability. This comprehensive review systematically reviewed the recent research advances in flame-retarded SR materials and summarized and introduced the up-to-date design of different types of flame retardants and their effects on flame-retardant properties and other performances of SR. In addition, the related flame-retardant mechanisms of the as-prepared flame-retardant SR materials are analyzed and presented. Moreover, key challenges associated with these various types of FRs are discussed, and future development directions are also proposed.

Towards the Reuse of Fire Retarded Polyamide 12 for Laser Sintering.

The control of powder aging during Selective Laser Sintering (SLS) processing is one of the challenges to be overcome for the implementation of this technique in serial production. Aging phenomena, because of the elevated temperatures and long processing times, need to be considered when a fraction of the polymer powders present in the build chamber and not used to manufacture the parts are reused at various times. The aim of this study was to investigate the influence of successive reuse of blends of pure Polyamide 12 and its blends with two types of flame retardants (FR): ammonium polyphosphate (APP) and zinc borate (ZB). The composition of the blends was 70/30 (wt/wt) PA 12/FR. Four successive processing stages have been carried out by collecting the remaining powder blend each time. The powders were re-used using the same processing parameters after sieving. DSC measurements showed that the incorporation of FRs entailed a reduction in the processing window up to 4 °C; nevertheless, no further reduction was noted after aging. The TGA curves of aged blends of powders were also similar for pure PA 12 and PA 12 with FR. In addition, initial and reused powders presented a higher degree of crystallinity than the specimens processed from the powders. The heterogeneous character of the PA 12 after LS processing or reprocessing was shown through Pyrolysis Combustion Flow Calorimetry (PCFC) and cone calorimeter (CC) tests. FTIR analysis also showed that post-condensation reactions have occurred. The mode of action of the flame retardants was clearly seen on HRR curves at both tests. The first reuses of PA 12 powders entailed a significant reduction in time to ignition at the cone calorimeter (150 for the initial material to around 90 s for the reused material), indicating the formation of short polymer chains. Only in the case of zinc borate was it noticed that re-used powder was detrimental to the fire performance because of a strong increase in the value of pHRR (between 163 and 220 kW/m2 for reused material instead of 125 kW/m2 for the initial one).

Mechanical, Dielectric and Flame-Retardant Properties of GF/PP Modified with Different Flame Retardants.

With the rapid development of electronic information technology, higher requirements have been put forward for the dielectric properties and load-bearing capacity of materials. In continuous glass fiber-reinforced thermoplastic composites, polypropylene matrix is a non-polar polymer with a very low dielectric constant and dielectric loss, but polypropylene is extremely flammable which greatly limits its application. Aiming at the better application of flame retardant-modified continuous glass fiber-reinforced polypropylene composites (FR/GF/PP) in the field of electronic communication, the effects of four different kinds of flame retardants (Decabromodiphenyl ethane (DBDPE), halogen-free one-component flame retardant (MONO), halogen-free compound flame retardant (MULTI), and intumescent flame retardant (IFR)) on the properties of FR/GF/PP were compared, including the mechanical properties, dielectric properties and flame-retardant properties. The results showed that among the FR/GF/PP, IFR has the highest performance in mechanical properties, MULTI has better performance in LOI, DBDPE and IFR have better performance in flame retardant rating, and DBDPE and IFR have lower dielectric properties. Finally, gray relational analysis is applied to propose an approach for selecting the optimal combination (flame retardant type and flame-retardant content) of comprehensive performance. In the application exemplified in this paper, the performance of IFR-3-modified GF/PP is optimized.

Factors impacting human exposure to legacy and emerging contaminants in residential dust in Beijing, China: Characteristics of indoor microenvironment

Exposure to indoor dust is of concern since dust may be contaminated by various toxic chemicals and people spend considerable time indoors. Factors impacting human exposure risks to contaminants in indoor dust may differ from those affecting the loadings of contaminants, but the dominant factors have not yet been well clarified. In this study, the occurrence, human exposure, and related influencing factors of several classes of legacy and emerging contaminants in residential dust across Beijing were investigated, including per- and polyfluoroalkyl substances (PFASs) and three types of flame retardants (FRs), i.e., organophosphate esters (OPEs), polybrominated diphenyl ethers (PBDEs), and novel halogenated FRs (NHFRs). OPEs (median: 3847 ng/g) were the most abundant group, followed by PBDEs (1046 ng/g) and NHFRs (520 ng/g). PFASs (14.3 ng/g) were one to two orders of magnitude lower than FRs. The estimated daily intakes of these contaminants were relatively higher for toddlers than other age groups, with oral ingestion being the main exposure pathway compared with dermal contact. Higher human exposure risks were found in new buildings or newly finished homes due to the elevated intake of emerging contaminants (such as OPEs). Furthermore, higher risks were also found in homes with wooden floors, which were mainly associated with higher levels of PFASs, chloroalkyl and alkyl OPEs, compared with tile floors. Citizens in the urban area also showed higher exposure risks than those in the suburban area. The quantity of household appliances and finishing styles (simple or luxurious) showed an insignificant impact on overall human exposure risks despite their significant effect on the levels of some of the dust contaminants. Results in this study are of importance in understanding human exposure to the co-existence of multiple contaminants in indoor dust.

Non-combustible polymer composites with extremely high filler loading via polytetrafluoroethylene fibrillation

The incorporation of halogen-free flame retardants (FRs) into polymer matrices is a cost-effective and eco-friendly method for suppressing flames and smoke and enhancing fire safety. In energy applications, a high FR loading (e.g., >80 wt%) is often necessary owing to the excessive heat and toxic gases generated by the devices and components. However, achieving this in conventional polymer composites is significantly impeded by poor processability stemming from increased melt viscosity. This study proposes a new approach to fabricate highly loaded flame-retardant composites with an extremely high FR content of 95 wt% via fibrillation of thermally stable polytetrafluoroethylene (PTFE), which holds two different types of FRs, magnesium hydroxide (MH) and expandable graphite (EG). The hybrid composites exhibit excellent flame retardancy owing to the synergistic effects of the distinct mechanisms of the two fillers, securing a top V-0 rating in the UL-94 vertical burning test and a limiting oxygen index (LOI) exceeding 95 %. Importantly, their total heat release (THR) from the cone calorimeter test is less than 1 MJ/m2, an anomalously low value that meets the criteria for non-combustible materials (THR <8 MJ/m2). Alongside their non-combustible attributes, the composites also have high thermal conductivity, reaching up to 1.60 W/m·K, due to the presence of thermally conductive EGs. We believe that these composites and their fabrication methodology can offer new insights into the design of flame-retardant composites, which are likely to be applicable in practical applications involving severe fire hazards, such as batteries, electronics, and electric vehicles.

Evaluations of the effects of different flame retardants combinations on particleboards produced using urea–formaldehyde resin

Nowadays, using flame-retardant chemicals is gaining importance in chipboard production. Melamine resins to produce chipboard are preferred to provide flame retardancy properties with a cost of approximately 2.5 times the urea–formaldehyde (UF) resin. In this study, the UF resin to produce the chipboard was preferred due to its economical availability. To improve the flame retardancy properties of the chipboard, phosphate-based and inorganic flame retardants were used in the chipboards. In chipboard production, oak, pine, poplar, sawdust, urea–formaldehyde resin as adhesive, flame retardant chemicals like triphenyl phosphate (TPP), ammonium polyphosphate (APP), and calcium gluconate (CaG) were used. Flame retardant chemicals were added to chipboards in single and double compositions and prepared by pressing method. Mechanical (tensile, bending, and surface strength), physical (humidity, density, formaldehyde emission), and fire (limiting oxygen index (LOI), cone calorimeter, and UL-94 vertical) tests were performed on wooden boards. It has been observed that the use of different types of flame retardant and their combinations in chipboard does not significantly change the mechanical properties. It was seen that the free formaldehyde emission rate decreased by using flame retardant added compared to the control sample. The chipboard samples with added flame-retardant chemicals have entered the V-0 rating in the UL-94. LOI values of the chipboard samples containing 50% CaG-50% APP and 50% TPP—50% CaG were observed as 29.7% and 29.8%, respectively. Besides, the highest heat release rate (HRR) reduction was obtained in the chipboard sample containing 50% CaG—50% APP.

Flame Retardant Additives Used for Polyurea-Based Elastomers—A Review

The growing interest in modern polymer materials has targeted research on complex plastic coatings and the possibilities of modifying their features and properties during manufacturing. Today’s modern coatings, including polyurea and polyurethane, are among the most modern developed resins. Compared to other polymer coatings, they are distinguished by their versatility, strength, and durability. They undoubtedly represent the next step in the evolution of coatings. Advances in coating technology have also led to the development of spray, injection, and roto-cast application equipment, improving polyurea-based elastomers’ performance. For many years, there has been much interest in increasing the flame resistance of polymers. This is dictated by safety considerations and the increasing requirements for the flammability of plastics, the area of application of which is growing every year. This text attempts to provide an overview of current research on flame retardant composites. Particular attention was paid to polyurea (PU) and polyurea-based hybrids and the application areas of polyurea coatings. The paper defines flame retardants, discusses how they work, and presents the types of flame retardants and the current trends of their usage in the production of plastics.

Development of a UiO-66 Based Waterborne Flame-Retardant Coating for PC/ABS Material.

The flame-retardancy of polymeric materials has garnered great interest. Most of the flame retardants used in copolymers are functionalized additives, which can deteriorate the intrinsic properties of these materials. As a new type of flame retardant, functionalized metal-organic frameworks (MOFs) can be used in surface coatings of polymers. To reduce the flammability, a mixture of phytic acid, multi-wall carbon nanotubes, zirconium-based MOFs, and UiO-66 was coated on a PC/ABS substrate. The structure of the UiO-66-based flame retardant was established by FT-IR, XRD, XPS, and SEM. The flammable properties of coated PC/ABS materials were assessed by LOI, a vertical combustion test, TGA, CCT, and Raman spectroscopy. The presence of a UiO-66-based coating on the PC/ABS surface resulted in a good flame-retardant performance. Heat release and smoke generation were significantly reduced. Importantly, the structure and mechanical properties of PC/ABS were less impacted by the presence of the flame-retardant coating. Hence, this work presents a new strategy for the development of high-performance PC/ABC materials with both excellent flame-retardancy and good mechanical properties.

Optimization and verification of selective removal of organophosphate esters from wastewater by molecularly imprinted adsorbent

Tributyl phosphate (TNBP), a new type of flame retardant, is an emerging pollutant and has been frequently detected in various matrices such as wastewater. Efficient removal of TNBP is critical for wastewater treatment. In this study, molecularly imprinted polymer (MIP) was prepared using precipitation polymerization for selective adsorption of TNBP. The results showed that MIP had a porous structure and formed effective imprinting cavities, which was primarily responsible for its superior adsorption ability. The adsorption of TNBP by MIP was carried out following both the pseudo-secondary kinetic model and the Langmuir isothermal adsorption model. MIP adsorbed TNBP rapidly and reached adsorption equilibrium within 30 min with 923 μmol g−1 at 298 K. The adsorption capacity and adsorption rate of MIP were respectively 2 and 5.49 times those of non-molecularly imprinted polymers. In addition, MIP could effectively counter disturbances from external parameters like temperature and pH, exhibiting strong environmental flexibility. MIP can specifically adsorb organophosphate esters, and can selectively adsorb TNBP under the interference of coexisting contaminants such as1,3-diphenylguanidine and isazofos. In actual bodies of water, MIP's highly selective adsorption of TNBP retains its advantage. The selective adsorption of MIP was mainly due to the common phosphate skeleton, and the specific substituent of organophosphate esters played an important role in the imprinting process. Hydrogen bonding might be involved in the polymerization process of TNBP with acrylamide and the adsorption process of TNBP by MIP.MIP exhibited good reuse efficiency, the total adsorption capacity decreased by no more than 25% after 7 reuse cycles. This study provides a simple and efficient method for selective removal of organophosphate from wastewater.

Enhanced safety and strength of cotton fabrics through a novel ‘H-shaped’ multiple flame retardant elements agent

In response to the new concept of green sustainability, it is necessary to expand the functionality of bio-based natural fibers (such as cotton fabrics) to replace fabrics made from fossil fuels. One potential way of achieving this is through the use of phosphorus, boron and nitrogen based organic flame retardants. This article designs a special flame retardant system with high efficiency, high durability, and enhanced fabric strength. An “H” shaped flame retardant (TBSA) is synthesized using hydroxyethyl methylene phosphate, pentaerythritol diborate, and cyanuric chloride. After simple treatment, flame retardant fabric (TBSA/Cotton) is obtained, with a LOI value of 48.8 %. Self extinguishing is completing in the vertical flame test. The high FR efficiency reflects the progressiveness of multi flame retardant elements. It is worth noting that TBSA/Cotton exhibits excellent durability and improves the strength of the fabric. This is attributed to the covalent bonding between the “H” type flame retardant and multiple cellulose molecules, which compensates for the cracks and holes at the submicroscopic scale of natural cellulose and weakens the molecular slip effect. The research results of this article provide a good opportunity for the development of biomass cellulose flame retardant materials.

Application of Halogen-Free EPDM Flame Retardants

Flame retardant materials have been widely used in different fields because of their unique physical and chemical properties, such as aerospace and chemical products. However, although the traditional halogen-based flame retardant has shown excellent application performance in the actual application process, there are serious environmental pollution problems after its use. In order to solve the environmental problems caused by halogen flame retardants, different types of environmentally friendly flame retardant materials have been developed, such as ethylene propylene diene monomer (EPDM) flame retardant. As a new type of energy saving and environment friendly rubber, the EPDM has excellent heat resistance, aging resistance, corrosion resistance and insulation performance, and thus it has been widely used in all walks of life. To this end, EPDM has been used to develop different types of flame retardant materials. Herein, this research will mainly analyze the application performance of different types of EPDM flame retardants and their flame retardant mechanisms, where the research and application of EDPM flame retarder are mainly described from three aspects: intumescent flame retarder, phosphorous flame retarder and inorganic flame retarder

Enhanced strength and synergistic flame retardancy of PE-base nanocomposites with coating-modified palygorskite clay

Polyethylene (PE) - base nanocomposites composed of high density polyethylene (HDPE) as matrix and coating-modified palygorskite clay (MAT) as functional filler and fire resistance was prepared by melt blending method. The MAT powder was prepared by solution heterogeneous precipitation method combined with spray drying processes. The microstructure observation shows that the particle size of the obtained MAT powder was concentrated and even. Both mechanical properties and thermal behaviors of the nanocomposites containing MAT were compared to those with commercial ceramic fillers (naming as S type flame retardants) at the same addition mass ratios level. The added MAT mass fractions in the composite were defined as 5 wt%, 10 wt%, 15 wt%, and 20 wt%, respectively. When the addition amount of MAT is 15 wt%, the impact toughness of MAT/HDPE composites approaches 13.41 kJ/m2, which is better than that with commercial fillers. The added fractions of MAT increases to 19.1 wt%, and the elongation at break of nanocomposite reaches 495%, which is much higher than that with S type flame retardants. The differential scanning calorimeter (DSC) test results show that MAT can enhance the melting point range of HDPE and improve the thermal stability of the composite. The LOI (limiting oxygen index) results confirm that MAT can effectively improve the flame retardancy of HDPE composites, and the LOI value increases with the MAT addition. The enhancement of mechanical and thermal properties of the PE-base composite is essentially originated from the uniform dispersion of MAT in polymer matrix and the strong interactions with inorganic – organic interface compatibility.

ЭФФЕКТИВНОСТЬ ОГНЕЗАЩИТНЫХ ПРОПИТОЧНЫХ СОСТАВОВ ДЛЯ ДЕРЕВЯННЫХ КОНСТРУКЦИЙ

The article considers the results of evaluating the flame retardant effectiveness of various flame retardants by the method of fire exposure according to GOST 53292–2009 and by methods of thermal analysis (thermogravimetry, differential thermogravimetry, derivative thermal analysis). According to the results of fire of surface application of flame retardants from 350 to 550 kg/m2, group I or II of flame retardant&#x0D; efficiency is provided (mass loss from 8,67 to 25 %). It is shown that the group of flame-retardant effectiveness does not actually reflect the nature and degree of realization of the mechanism of flame retardant action of flame retardants, their ability to influence the features of thermal transformations of wood. It has been established that the type of flame retardant, its chemical component composition and the mechanism of flame retardant action to varying degrees affect the main stages of thermal oxidative decomposition of wood. The results obtained can be used to evaluate the effectiveness of fire protection in reducing the intensity of the charring process and predicting the intensity of smoldering (flameless) combustion of wood. tests, it was found that with the consumption

Synthesis and performance study of sulfur-containing amino acid ammonium phosphate type flame retardants for cotton fabric

In order to obtain cotton fabrics with high efficiency flame retardance, a new ammonium phosphate type active flame retardant N, N -bis (ammonium phosphate) cysteine (NP-BG), which is nonleaching, covalent attached, durable, functional flame retardants, was synthesized by Mannich reaction and applied to the flame-retardant modification of cotton fabrics. Test results such as FTIR and XPS showed that cotton fabrics had been successfully grafted with NP-BG. The LOI of cotton fabrics treated with 30 % flame retardant was as high as 40.2 %, and after 50 washes, the LOI of cotton fabric was still as high as 28.8 %; demonstrating the durability of flame retardance. The thermogravimetric-infrared coupling (TG-FTIR) test results showed that the flame retardant could change the thermal decomposition pathway of cotton fabric and produce a large amount of residual carbon, thus reducing the decomposition of cotton fiber and the release of flammable gas. In addition, cone calorimetry (CONE) experiments showed that the total heat release (THR) and heat release rate (HRR) of cotton fabrics were significantly reduced after the flame-retardant treatment. These findings indicate that NP-BG is a new flame-retardant material with good application prospects.

Analysis of mechanical and flame‐retardant properties of flexible polyurethane foams

AbstractIn this study, the mechanical and flame‐retardant properties of flexible polyurethane foams (FPUF) were analyzed as a function of the type of flame retardant. FPUF containing equal amounts of two halogenated flame retardants (tris 2‐cloropropyl phosphate [TCPP] and phosphinyl alkyl phosphate ester) and three halogen‐free flame retardants (melamine, melamine cyanurate, and expandable graphite) were considered. The foaming properties of these samples were analyzed by studying the rise time and settling rate using cup foaming. Square foaming was used to analyze the mechanical properties, including density, elongation, tensile strength, and tear strength. In addition, Fourier‐transform infrared spectroscopy was performed, and flame retardancy was evaluated using a horizontal flame test and the limited oxygen index. A cone calorimeter test was also performed to evaluate the combustion characteristics. In FPUF containing the same ratio of flame retardant (15% of the total polyol), the properties of urethane foam blended with expandable graphite were improved; the tensile strength of this blend is 20% higher than that of samples containing melamine, and its peak heat release showed a 70% reduction compared to that of samples containing TCPP. These findings provide valuable reference information for developing flame retardants for fire safety FPUF in the near future.

Flame Retardant Performance of Oak Plywood According to Main Ingredients of Flame Retardant

The purpose of this preliminary study was to analyze the effectiveness and variability of the flame retardant performances of different flame retardants with different main ingredients. This study selected plywood made of oak and three types of flame retardants with different main ingredients. The flame retardant performance measurements were conducted according to Article 31, Paragraph 2 of the “Enforcement Rule of the Fire Safety Installation and Management Act” and Article 7-2 of the “Flame Retardant Performance Test of Flame Retardant Materials.” The flame retardant performance of the plywood was also measured according to the domestic legal standard. The following conclusions were drawn. First, the after-flame and after-glow times were both measured as 0 seconds regardless of the flame retardant treatment. This was presumed to be because oak plywood is made from a species of oak tree that is naturally fire-resistant owing to its thick bark layer. Second, the flame retardant performances differed depending on the main ingredient of the flame retardant used on the oak plywood. The experimental results confirmed that a phosphorus mixture was the most effective main ingredient. Third, based on the results of this study and previous studies, it was confirmed that flame retardant performances vary depending on their main ingredients and composition ratios, as well as according to the tree species and type of flame retardant. Therefore, it is necessary to continue researching and comparing flame retardant performances through quantitative measurements based on the main ingredients and composition ratios for various tree species and flame retardants.

Cooperative Effect of Chemical and Physical Processes for Flame Retardant Additives in Recycled ABS.

In the present work, the effectiveness of four non-halogenated flame retardants (FR) (aluminium trihydroxide (ATH), magnesium hydroxide (MDH), Sepiolite (SEP) and a mix of metallic oxides and hydroxides (PAVAL)) in blends with recycled acrylonitrile-butadiene-styrene (rABS) was studied in order to develop a more environmentally friendly flame-retardant composite alternative. The mechanical and thermo-mechanical properties of the obtained composites as well as their flame-retardant mechanism were evaluated by UL-94 and cone calorimetric tests. As expected, these particles modified the mechanical performance of the rABS, increasing its stiffness at the expense of reducing its toughness and impact behavior. Regarding the fire behavior, the experimentation showed that there is an important synergy between the chemical mechanism provided by MDH (decomposition into oxides and water) and the physical mechanism provided by SEP (oxygen barrier), which means that mixed composites (rABS/MDH/SEP) can be obtained with a flame behavior superior to that of the composites studied with only one type of FR. In order to find a balance between mechanical properties, composites with different amounts of SEP and MDH were evaluated. The results showed that composites with the composition rABS/MDH/SEP: 70/15/15 wt.% increase the time to ignition (TTI) by 75% and the resulting mass after ignition by more than 600%. Furthermore, they decrease the heat release rate (HRR) by 62.9%, the total smoke production (TSP) by 19.04% and the total heat release rate (THHR) by 13.77% compared to unadditivated rABS; without compromising the mechanical behavior of the original material. These results are promising and potentially represent a greener alternative for the manufacture of flame-retardant composites.
