Abstract
Our research aimed to find a new material that can be an efficient heavy metal free flame retardant for plasticized poly(vinyl chloride) comparable to the conventional flame retardants. One of these extraordinary materials is Oxydtron using as an admixture for concrete. Oxydtron showed unexpected efficiency as a flame retardant agent and an excellent heat stabilizer as well. Limiting oxygen index (LOI), static heat stability, Congo-red, and differential scanning calorimetry (DSC) were carried out. The thermal tests proved that Oxydtron is suitable to improve plasticized poly(vinyl chloride) performance at high temperatures applications in terms of flame retarding and thermal stability. Therefore, the positive result obtained by the addition of Oxydtron is reducing of plasticized poly(vinyl chloride) flammability by 25.23%, and increasing its thermal stability as well.
Highlights
Most of conventional flame retardants and stabilizers for plastics contain heavy metals or other ingredients e.g. bromine being potentially harmful to the environment or health
The flame retardation of poly(vinyl chloride) is increasingly rising with increasing of Oxydtron percentage additives, where we can note from the third bar that L.O.I for poly(vinyl chloride) reached to 25.5% after adding 3% Oxydtron; and the optimum L.O.I value was obtained by 5% Oxydtron addition (27.8%) as shown in fourth bar; where the flame retardation improvement rate reached to 25.22% more than poly(vinyl chloride) basic formulation
This behavior of flame retarding can be explained by understanding the working mechanism of Oxydtron as flame retardant which does not depend on the changes that occur in its structure when exposed to high temperatures but depends on creating additional stabilizing synergistic action with the original stabilizer as were discovered that the Oxydtron is an excellent polymer stabilizer and proved by the thermal tests
