EVA/intumescent agent flame retardant composite materials using organic/inorganic hybrid filler

Ethylene vinyl acetate copolymer as the ethylene vinyl acetate (EVA) is used in various fields, because EVA has wide se-lection of properties. Recently, eco-friendly flame retardants have been actively research. Securing of flame retardants is very important, especially for the purpose of expanding the polymer. In this study, in order to develop a category of non-halogen flame retardants, intumescent agent system was introduced. Intumescent agent system - Ammonium phosphate monobasic (APP), Pentaerythritol (PER), Melamine (MEL) consisting of three substances - has demonstrated good miscibility with EVA, and the composite excellent flame-retardant properties to be implemented. By the hybrid system, mechanical properties of intumescent agent composite are dramatically increased. Polypropylene (PP) hybrid system is very useful method for improving mechanical properties
