Effect of vinyl acetate content and electron beam irradiation on the flame retardancy, mechanical and thermal properties of intumescent flame retardant ethylene-vinyl acetate copolymer

► The TG-IR analyzes the different gas products of EVA composites. ► The Cone data indicate that EVA2 composites with 28% VA content have the highest safety in a fire hazard. ► The LOI values of EVA composites increase with the increase of the irradiation dose. ► The mechanical and thermal properties of the EVA composites could be evidently improved at appropriate irradiation dose.
