Utilizing Coconut Biochar as a Bio‐reinforcing Agent in Natural Rubber Composites

AbstractThis research investigates the pyrolysis of biochar from different parts of residual aromatic young coconut waste, namely coconut fruit, coconut bunch, and coconut leaf, to be used as fillers in natural rubber (NR). Scanning electron microscopy coupled with energy dispersive X‐ray spectroscopy reveals that biochar has a flake‐like structure with a high carbon content (67%–77%). The biochar is mixed with NR using a two‐roll mill at filler contents of 0, 10, 20, 30, and 40 phr (part per hundred of rubber). Adding coconut fruit biochar at 40 phr increases the Shore A hardness to 59.62, a remarkable 47% improvement compared with unfilled NR. The maximum tensile strength occurs at 20 phr, while the highest tensile modulus (4.53 MPa) and tear strength (17,344 N m−1) are observed at 40 phr. Moreover, the swelling index of composites in toluene decreases slightly as biochar content increases, and the crosslink density is higher for NR filled with coconut fruit biochar than for other biochar types. Based on these results, coconut fruit biochar is identified as the most effective reinforcement filler for NR among the biochar types studied. Consequently, it can be used as a bio‐reinforcing agent in NR composites, contributing to sustainability and eco‐friendliness.

Natural rubber composites reinforced with sodium sulfate waste from pigment industry: A circular economy approach for solid waste management

The massive industrial waste discharged into the environment adversely affects the ecological system. Traditional methods like landfilling or other disposal methods can no longer be adequate to handle them, and their reutilization is consequently gaining popularity. Most chemical industries generate a large amount of sodium sulfate waste (SSW), contaminating air and water. Hence, its reutilization in natural rubber (NR) as a reinforcing filler is explored. SSW generated in Ultramarine and Pigments Ltd., Chennai, India, was procured and characterized. The fabricated NR-SSW composite's cure, mechanical, and sorption features have been investigated. NR composite with 7.5 phr (parts per hundred of rubber) SSW showed a 9 %, 14 % and 29 % increase in tensile strength, tear strength, and modulus at 300 % elongation, respectively, and a remarkable decrease in abrasion loss and higher abrasion resistance index (ARI) as compared to NR-Neat. All these properties decreased beyond 7.5 phr SSW addition, proving its better adhesion on NR up to 7.5 phr loading. The experimental tensile strength showed a good correlation with Turcsányi-Pukànszky-Tüdõs (T-P-T) model, confirming the better matrix-filler interaction up to 7.5 phr SSW loading. Sorption studies proved the better barrier properties of NR-SSW7.5 composite compared to NR-Neat. Various kinetic parameters were studied, and a suitable transportation method was suggested. NR-SSW7.5 composite, having remarkable mechanical and barrier properties, finds application in various rubber products manufacture. The reutilization of SSW as an efficient filler in NR is an innovative attempt from a circular economy perspective, as it reduces production costs and environmental pollution.

Influence of multi-walled carbon nanotubes on thermal behaviour and mechanical properties of pineapple leaf fibre-based natural rubber composites

Replacing synthetic fibres with natural fibres as reinforcement fillers in natural rubber (NR) tends to yield eco-friendly bio-composites. This study investigated the tensile and hardness properties, and the thermal behaviour of pineapple leaf fibre (PALF)-reinforced NR composites with and without the addition of multi-walled carbon nanotubes (MWCNT). The fibre content was varied at 0, 10, 20, and 30 parts per hundred rubber (phr) and the MWCNT content was fixed at 10 phr. The surface morphology of the tensile-fractured specimens was examined using scanning electron microscopy (SEM) to identify the rubber-matrix adhesion and tear mechanisms of the fibres in the NR matrix. The results revealed that including the PALF and MWCNT allowed the NR composites to exhibit excellent stretching stress at low elongations. Additionally, the composites displayed enhanced stiffness, further increasing the hardness of the composite, ranging from 46.8 to 62.8 Shore A. However, PALF reduces the thermal stability of the composite, where the initial degradation temperature increases. From the thermogravimetric analysis, the residues remaining in the NR composites ranged from 6 to 13% at various fibre loadings. Therefore, this study provides valuable insights into the tensile and hardness properties and the thermal behaviour of PALF-reinforced NR composites to improve end-use properties.

Cure Behaviour and Tensile Properties of Pineapple Leaf Fibre Reinforced Natural Rubber Composites

Short natural fibres replace synthetic fibres as filler in natural rubber (NR) as they are environmentally beneficial and sustainable. This study investigates the cure behaviour and tensile properties of pineapple leaf fibre (PALF) reinforced NR composites at various fibre contents. The fibre contents are varied at 0, 10, 20 and 30 parts per hundred rubber (phr). PALF reinforced NR composites are prepared using a two-roll mill. Surface morphology of tensile fractured specimens is examined using scanning electron microscopy (SEM). The results demonstrated that the optimum cure time decreases significantly with greater fibre content. The hardness value increases gradually with increasing filler content. The stress-strain graphs show an increasing trend in stress at higher fibre content particularly at low strain regions. On the contrary, the tensile strength reduces when the fibre content is increased up to 30 phr. SEM analysis reveals that the fibre-matrix adhesion is considerably poor due to the fibre pullout phenomenon observed. It is indicated that higher fibre content could be possibly reinforced to NR to achieve high deformation stress at incredibly low strain regions.

Structure and properties of ZnO‐organobentonite‐filled natural rubber composites

AbstractThis study involved the preparation of composites consisting of zinc oxide (ZnO) nanoparticles deposited within the structure of organophilic bentonite. These composites were subsequently utilized as fillers in natural rubber (NR). The organobentonites were initially prepared via a cation exchange reaction using alkylammonium ions with different chain lengths (C8N−C18N) and later deposited by ZnO nanoparticles. The identification of the ZnO‐organobentonites was conducted using various techniques, including powder X‐ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), UV‐Vis spectroscopy, etc. The findings demonstrate the successful deposition of ZnO nanoparticles within the organobentonite's structure. The basal space between the silicate layers increased with the increasing chain length of alkylammonium ions. When added to NR, the ZnO‐organoclays mutually acted as a cure activator and filler. As expected, the ZnO‐organoclay modified by octadecylammonium ions (C18N) showed the greatest reinforcement due to its highest capability to enlarge the basal space between the silicate layers.

Mechanical characteristics and regression models of rice husk silica reinforced natural rubber composites

Carbon black and silica fillers have been widely used as reinforcing fillers in tyres and engine mounts. However, both fillers are non-renewable and with REACH legislation in Europe, the USA and elsewhere, where some of these fillers are termed hazardous due to the presence of polyaromatic hydrocarbons (PAHs), there is a need to search for sustainable alternative fillers to wholly or partially replace carbon black as a filler. This research studied rice husks-derived silica (RHS) as a filler in natural rubber (NR). The characteristics of RHS at 50 phr to 90 phr filler loading levels were examined to determine its suitability as a substitute for unsustainable carbon black (N772) fillers used in the rubber industry. Bound rubber content, crosslink density, tensile strength, young modulus, tear strength, shore A hardness, compressive set, and elongation at break were measured. Regression models were generated and the correlation of determination (R2) values was obtained. The RHS composites resulted in maximum tensile strength of 13.20 MPa at 90 phr, tear strength of 119 MPa at 90 phr, shore A hardness of 69 at 90 phr, compressive set of 6.72% at 80 and 90 phr, elongation at break of 453.60% at 80 phr, bound rubber content of 92.14% at 50 phr and crosslink density of 3.87×10-2 mol/cm3 at 70 phr. The results obtained were within the range of those obtained for the carbon black filled composites across various loading levels. The R2 value of mechanical characteristics for the RHS and N772 samples respectively were 50.06% and 62.18% (bound rubber content), 97.62% and 99.85% (tensile strength), 98.44% and 63.97% (tear strength), 89.16 and 97.40% (Shore A hardness), 32.90% and 91.80% (compressive set), a d 50.91% and 46.91% (elongation at break). Rice husk-derived Silica filled natural rubber composites showed favourable mechanical properties and can substitute traditional fillers in tyres, rubber engine mounts, bushings, seals and doormats.

Preparation of Calcium Carbonate from Cockle Shells as Fillers in Natural Rubber

The purpose of this research is to study the preparation of calcium carbonate from cockle shells by precipitation method and compare it to calcium carbonate from high temperature heating, commercial calcium carbonate, and cockle shell powder. The properties of the vulcanized natural rubber mixed with different types of calcium carbonate were observed. It appeared that the precipitated calcium carbonate delivered the best properties (hardness, 300% modulus, tensile strength, elongation at break, tear strength, and abrasion resistance), followed by the high temperature heated calcium carbonate, the commercial calcium carbonate, and the cockle shell powder, respectively. This result corresponded to the morphology from the scanning electron microscope (SEM); the precipitated calcium carbonate had crystalline form and the most uniform particle size, followed by the high temperature heated calcium carbonate, the commercial calcium carbonate, and the cockle shell powder. In particular, the cockle shell powder was composed of large and small particles dispersed over a wide range, which brought about the weak point of vulcanized rubber and caused the lowest properties of the vulcanized rubber mixed with cockle shell powder.

Natural Rubber Composites Using Hydrothermally Carbonized Hardwood Waste Biomass as a Partial Reinforcing Filler-Part II: Mechanical, Thermal and Ageing (Chemical) Properties.

Natural rubber composites were reinforced by the co-fillers 'hydrochar' (HC), obtained by hydrothermal carbonization of hardwood sawdust and commercial carbon black (CB). The content of the combined fillers was kept constant while their ratio was varied. The aim was to test the suitability of HC as a partial filler in natural rubber. Due to its larger particle size and hence smaller specific surface area, large amounts of HC reduced the crosslinking density in the composites. On the other hand, due to its unsaturated organic character, HC was found to display interesting chemical effects: if it was used as the exclusive filler component, it displayed a very strong anti-oxidizing effect, which greatly stabilized the rubber composite against oxidative crosslinking (and hence embrittlement). HC also affected the vulcanization kinetics in different ways, depending on the HC/CB ratio. Composites with HC/CB ratios 20/30 and 10/40 displayed interesting chemical stabilization in combination with fairly good mechanical properties. The performed analyses included vulcanization kinetics, tensile properties, determination of density of permanent and reversible crosslinking in dry and swollen states, chemical stability tests including TGA, thermo-oxidative aging tests in air at 180 °C, simulated weathering in real use conditions ('Florida test'), and thermo-mechanical analyses of degraded samples. Generally, the results indicate that HC could be a promising filler material due to its specific reactivity.

Utilization of high and low calcium oxide fly ashes as the alternative fillers for natural rubber composites: A waste to wealth approach

Recently, fillers from renewable resources or agricultural wastes have been considered as the alternative fillers to reduce the environmental problems. Therefore, utilization of the fly ashes (FA) collected from the electric power plants as the reinforcing filler in natural rubber (NR) composites was carried out and compared these high (HCaO) and low (LCaO) calcium oxides with carbon black (CB). The FA concentration was varied up to an optimum loading of 1000 parts per hundred rubber (phr) by using melt mixing technique. Particle size and chemical composition of HCaO and LCaO were reported and the properties of NR composites in terms of cure characteristics, Payne effect, mechanical and dynamical properties together with morphologies were examined. It was found that the addition of HCaO significantly reduced the vulcanization time of the NR composites, while the one with LCaO provided higher degree of reinforcement efficiency to the NR matrix. It clearly supports the relation of storage modulus as a function of strain sweep and their morphologies, which are the major requirements in case of composites. Upon increasing of FA loading, NR has changed its role from rubber matrix to an adhesive binder and therefore the Young’s modulus was found to be strongly changed. FA can be used to replace CB in NR composites with the composition ratios starting from 1:2–1:6 phr. Although, CB exhibited a slightly better reinforcing effect than FA, based on the lowered glass transition temperature (Tg), Tan delta (Tan δ) exhibited the same elasticity and CB can be replaced in case of several CB-based composites, particularly, the artificial wood, car stopper and tire industries to produce rubber belt and bead.

Nanosilica Particulate Magnetic as Alternative Filler on Natural Rubber Composites with Human-Tissue-Like Mechanical Characteristic

There have been no reports of the simultaneous application of natural fillers, such as magnetite and natural zeolites, to increase the strength of composites containing silica (SiO2) fillers as reinforcing fillers in natural rubber. This study has investigated the effect of magnetically modified natural zeolite on nanosilica-reinforced natural rubber composites that include a mechanical characteristic like human tissue. We use technical specifications rubber (TSR) SIR 20 with nanosilica reinforced fillers and Titanate coupling agent (TCA) as fillers and elastomer binders. The results showed that the nanosilica-zeolite-magnetite (Fe3O4) mixture had an influence on strength and stiffness and could be a substitute filler. The precursors made with some variations include the optimization of filler and the optimization volume fraction of nanosilica. Mechanical characteristics of different human body part tissue were compared to the control samples and have similar mechanical characteristics with internal human tissue characteristic. Based on these results, nanosilica fillers combine with magnetically modified zeolites and titanate coupling agents, potentially as an alternative filler to replace carbon black, and are applicable for synthetic muscle replacement cadavers with a customized formula.

Development of natural rubber-bamboo biochar composites for vibration and noise control applications

The present study focuses on the utilization of bamboo biochar (BB) as a filler in natural rubber (NR) composites. This work is the first attempt to investigate the influence of BB loading on the vibration damping and acoustical properties of NR composites. NR-BB composites were prepared according to the ASTM D3182-21a standard. Vibration damping and acoustical properties were examined using the Obrest beam (ASTM E756-05) and four microphone impedance tube (ASTM E2611-19) methods. Noteworthy, the vibration damping ratio or system loss factor (ξ) obtained maximum for the fourth mode of vibration (NR- ξ = 33.19, NR/10BB- ξ = 17.46, and NR/20BB- ξ = 13.50) in the free layer damping (FLD) configurations. However, the sound transmission loss (STL) was enhanced by 8% and 11% compared to NR composites upon adding 10 and 20 phr of BB, respectively. In addition to vibration damping and STL, the loading of BB in the NR matrix positively influenced physical, mechanical, and thermal properties.

In-situ preparation of TBIR/CB nanocomposites and its regulation in structure and properties of NR based composites

In order to construct the rubber nanocomposites with desired dual network structures, the trans -1,4-poly (butadiene-co-isoprene) copolymers (TBIR)/carbon black (CB) nanocomposites were prepared by in-situ polymerization in the presence of large amounts of CB using TiCl 4 -type Ziegler-Natta catalysts. It was found that the addition of CB had no obvious negative effects on the catalytic behaviors. Further, the TBIRCB were used to modify NR and the NR/TBIRCB vulcanizates were investigated. Compared with the NR compound, the NR/TBIRCB compounds presented weakened Payne effects and increased bound rubber contents with the increase in CB filling in TBIRCB. Compared with NR and NR/TBIR vulcanizates, the NR/TBIRCB46 vulcanizate with features like excellent filler dispersion and high CB in-situ filling, enhanced interaction between CB and rubber matrix and special polymer network structure constructed from NR/TBIR matrix, showed outstanding comprehensive properties, including greatly reduced rolling resistance, much lower heat built-up and increased abrasion resistance. • Synthesis of new synthetic rubber composites by in-situ polymerization. • NR/TBIRCB46 vulcanizate improve the dispersion of filler in natural rubber. • The rolling resistance, heat build-up and wear of NR/TBIRCB composites are significantly reduced.

Preparation of purified spent coffee ground and its reinforcement in natural rubber composite

Spent coffee ground (SCG) contains a variety of organic compounds such as fatty acids, amino acids, polyphenols, polysaccharides, etc. In this study, purification of SCG was carried out by alkalization and bleaching treatment and the purified SCG (PSCG) was characterized by various techniques, i.e., FTIR, XRD, BET, SEM and TGA. PSCG was later treated with Bis-triethoxysilylpropyl tetrasulfide (TESPT). Both PSCG and TESPT-treated PSCG were then incorporated into natural rubber (NR) to investigate their reinforcement magnitude in the bio-composite. Results revealed the eradication of lignin and other non-polysaccharide components after the purification leading to the significant increases in specific surface area and cellulose content of PSCG. Although the addition of PSCG into NR showed cure time reduction in association with the increased modulus and hardness, its reinforcement was not very high due to the large particle size and the abundance of hydroxyl groups in PSCG. The TESPT treatment significantly improved the reinforcement of PSCG due to the increases in rubber-filler interaction and crosslink density. However, the reinforcement of both PSCG and TESPT-treated PSCG is still relatively low compared to the commercial nanofillers and, thus, they can be considered as a cheap and eco-friendly filler in NR.

Improving the dispersion and reinforcing properties of peroxidated corn stover and sugarcane bagasse fibers in natural rubber compounds

The performance of peroxidated powdered fibers of corn stover and sugarcane bagasse as fillers in natural rubber was evaluated in this study. Powdered corn stover and sugar bagasse fibers were subjected to the conventional peroxidation treatment for conversion to more hydrophobic fillers with enhanced tensile properties. The physicochemical properties of the peroxidated fibers were assessed using standard methods. Morphological properties, thermal stability, and functional groups were also assessed. The treated and untreated fibers were then used as fillers in natural rubber compounding using the two-roll mill, compression moulding and subjected to physico-mechanical characterization. There was improved dispersion of the peroxidated fibers in the polymer matrix, which meant significant improvement in the reinforcement and mechanical properties of the natural rubber compounds. A morphological study of the composites showed that natural rubberperoxided fiber composites have very good dispersion in the rubber matrix. The mechanical properties showed that the composites have improved properties with the highest tensile strength of 44.55 MPa, modulus at 100% elongation of 6.11 MPa, elongation at break of 294%, hardness of 74.30 IRHD.

Reutilization of polyurethane-based shoe sole scrap as a reinforcing filler in natural rubber for the development of high-performance composites

Reutilization of industrial waste is one of the emerging strategies to combat solid waste disposal for the protection of our environment. The present work describes a novel and economic approach to reutilize finely ground shoe sole scrap, a thermoset polyurethane-based waste (PUW) material generated during shoe sole production in footwear industries as an efficient reinforcing filler in natural rubber (NR). Shoe sole scrap was ground to fine powder and characterized by various analytical techniques. NR-PUW composites were prepared using 0–20 phr (parts per hundred of rubber) of PUW. The cure characteristics, mechanical, thermal, and morphological properties of prepared composites were studied. Composite with 5 phr PUW showed a remarkable improvement in tensile strength by 10% and modulus at 300% elongation increased by 9% compared to that of neat sample. A considerable increase in abrasion resistance and tear strength was also observed in 5 phr PUW loaded composites. Other mechanical properties like hardness, heat build-up and compression set showed a regular increase with further filler loading. To estimate the level of interfacial adhesion between the filler and the matrix, the experimental values of tensile strength were compared with Nicolais–Narkis (N–N), Lu, and Turcsányi–Pukànszky–Tüdõs (T–P–T) models and elastic modulus values with Einstein and Guth and Smallwood models. The tensile strength values are in agreement with T-P-T model (B = 4), up to 5 phr PUW proving the better adhesion between NR and PUW at lower filler loadings. At higher PUW loading, the experimental results are approaching Lu and N–N models indicating that this adhesion is collapsed. The incorporation of PUW as a filler in NR does not adversely impact the thermal stability of prepared composites. The results obtained are not only promising from a circular economy perspective, but also is contributive in production of high-performance, low-cost NR composites for various industrial applications.

Use of exhausted biosorbent ash as ecofriendly filler in natural rubber

Biosorption is a promising cost-effective clean-up technology for treating wastewater laden with heavy metals. However, the commercial application of biosorption technologies has been limited because a large amount of toxic waste is left behind in this process. The post-sorbents need to be handled in a way that does not negatively affect the environment. In this research, one possibility to solve this problem was proposed and developed: incineration of used adsorbent, followed by the use of the obtained ash as a filler in rubber production. The results showed that the addition of biosorbent ash does not significantly affect the rubber mechanical and elastic properties. The ash addition affected only the beginning of the vulcanization by increasing the activation energy of the curing chemical reaction. This property can be used to prevent the premature start of vulcanization. Furthermore, it was determined whether and to what extent the ash-filled rubber releases metal ions in contact with water. Results showed that the amount of copper leached from rubber samples was negligible compared to the copper that remained permanently built in the rubber. Therefore, this novel approach to utilizing saturated biosorbents as rubber fillers is acceptable from the environmental safety perspective. © 2022 Society of Industrial Chemistry.

Synergistic effect between graphene nanoplatelets and carbon black to improve the thermal and mechanical properties of natural rubber nanocomposites

ABSTRACT In this study, we focused on the synergistic effect between carbon black (CB) and graphene nanoplatelets (GNPs) of various aspect ratios and specific surface areas as hybrid fillers in natural rubber (NR) nanocomposites. Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, and scanning electron microscopy (SEM) were carried out to characterize the GNPs properties, while dynamic mechanical analysis (DMA), tensile properties, hardness, thermal conductivity, swelling behavior in toluene and SEM were performed on the NR nanocomposites. The results showed the positive effect of GNPs on the thermal and mechanical properties, which was attributed to the high surface area and aspect ratio of the GNPs playing a vital role in producing a conductive GNPs/CB hybrid fillers’ network. Among the three GNPs investigated, the sample having the highest lateral dimension (25 µm) led to a denser and more thermally conductive network. On the other hand, the GNPs/CB hybrid fillers’ synergy increased with increasing concentration inside the NR nanocomposites up to 5 phr due to their good dispersion as confirmed via SEM.

The rheological and mechanical properties of natural rubber/graphene composites

This research focuses on the use of graphene as a filler for natural rubber (NR). The purpose of using graphene is to improve the mechanical properties of rubber compounds and their processing characteristics. Graphene (G) consists of carbon atoms and is an essential filler for polymers to enhance electrical and mechanical properties. The addition of graphene to rubber can improve the wear resistance and mechanical strength of rubber products. Thus, the effect of the graphene filler composition is interesting to study. Variety of graphene loads (10, 20, and 30 part hundred rubber (phr)) were combined with a variety of sulfur fillers (S) (10 and 20 phr) and then composited with natural rubber. The effect of variations in a load of graphene and sulfur fillers on the rheological properties, abrasion resistance, and compression set were studied. The results showed that the optimal combination of the G/S load variation was 20/10 phr. It leads to a more extraordinary strengthening ability that is binding rubber molecules so that the interactions occurred, both physical and chemical, could be formed better with the NR molecular chain. This resulted in distinct rheological properties enhancement such as torque modulus and curing time. In contrast, the mechanical properties like abrasion resistance and compression set were still good. The FTIR Spectra of natural rubber-graphene composites confirmed that good filler disperses were obtained due to several intramolecular interactions of carbon graphene with NR molecules. Graphene can be used as a filler for rubber products, mainly rubber, abrasion, and compression resistant, and an alternative for commercial fillers.

Effect of Organomodified Bentonite/Silica Hybrid Filler Compound System on Mechanical Properties and Sealing Performance of NR/NBR Rubber Seal for LPG Tube Valve

Organomodified bentonite and silica were used as hybrid fillers in natural rubber (NR)/nitrile butadiene rubber (NBR) seal for liquified petroleum gas (LPG) tube valve compound to evaluate their interaction and influence on mechanical properties and sealing performance. In this work, the NR-organomodified bentonite were prepared by the in situ organomodified and latex compounding method with varying amounts of bentonite then applied in the silica-NR/NBR rubber seal compounds with mixing process held in two rolls open mill. Silanization reaction, Payne effect, curing characteristics, tensile properties, compression set, hardness, uniaxial compression and sealing performance were assessed. The study obtained that NR/NBR-silica/organomodified bentonite show improved silica dispersion physically, as analyzed by Payne effect. The presence of organomodified bentonite decreases the vulcanization reaction. The cure rate index, apparent crosslink density and hardness tend to decrease with addition of organomodified bentonite, while tensile strength and elongation at break are enhanced with increasing organomodified bentonite. With an appropriate amount of organomodified bentonite (organomodified bentonite below 4 phr), the introduction of organomodified bentonite enhances the elastic response of the material, as shown by increasing of tensile properties. The rubber seal’s sealing performance analysis revealed that B4 (4 phr organomodified bentonite) performed the best, with contact stress higher than the actual working pressure and Misses stress lower than the actual working pressure, making it difficult to crack.

The effect of silica filler quartz sand from tailing processing of mining material on mechanical properties, thermal aging and morphology rubber compound

Tailings as waste from mining material processing contain constituents that have the potential to be exploited economically. Tailings deposits derived from tin mines include quartz sand with a SiO2 content of 98.03%, which can function as a filler for rubber products. This research studied silica quartz sand as a mineral filler in natural rubber (NR) on rubber’s mechanical and thermal aging characteristics. The effect of reinforced filled in NR was observed by varying 0, 10, 20, 30, 40, and 50 phr of the filler. The thermal aging test is carried out at 70 °C and 100 °C for a storage period of 72 hours. SEM micrographs were used to examine morphology. The results showed that using silica quartz sand as a filler improved various properties, including tensile strength, tear strength, elongation at break, hardness, and abrasion resistance. The higher the grinding temperature, the higher the hardness and tensile strength, but the lower the elongation at break. Morphological analysis using SEM micrographs revealed the system’s strengths and weaknesses. The silica particles are homogeneously mixed with natural rubber, according to SEM analysis. According to the findings of this study, the silica of quartz sand from tin mining processing industrial waste can be used as a cost-effective alternative filler in NR compounding.
