Thermal properties of materials based on ethylene vinyl acetate and various flame retardants during thermal oxidative degradation

Abstract

The paper presents a comparative study of the influence of various flame retardants on the process of thermo-oxidative decomposition of ethylene vinyl acetate. The degree of influence of different groups of flame retardants on the thermal stability of the polymer composition, on the processes of ethylene vinyl acetate degradation at different stages in a wide temperature range is described. It was found that the flame retardants used tend to increase the thermal stability of the polymer composition, shift the intervals of polymer decomposition to a higher temperature region, while reducing the value of mass loss. Flame retardants form refractory and highly condensed phases that affect the process of outgassing during decomposition of polymer compositions.
