Effect of intumenscent flame retardant (IFR) on thermal properties of ethylene vinyl acetate (EVA)/zeolite composites

摘要

This paper describes the effect of intumenscent flame retardant (IFR) on thermal properties of ethylene vinyl acetate (EVA)/zeolite composites. EVA/zeolite composites were prepared using Thermo Haake Polydrive internal mixer and were then compression molded according to standard test specimen. The results of TGA showed that both types of flame retardants have the ability to enhance the thermal stability of EVA/zeolite composites. Meanwhile the results of vertical burning testing (UL-94-V) and limiting oxygen index (LOI) measurement revealed that the flame retardants could also reduce the flammability of the composites by achieving V-0 UL94-V rating and increased LOI value, respectively.
