Application of Halogen-Free EPDM Flame Retardants

Abstract

Flame retardant materials have been widely used in different fields because of their unique physical and chemical properties, such as aerospace and chemical products. However, although the traditional halogen-based flame retardant has shown excellent application performance in the actual application process, there are serious environmental pollution problems after its use. In order to solve the environmental problems caused by halogen flame retardants, different types of environmentally friendly flame retardant materials have been developed, such as ethylene propylene diene monomer (EPDM) flame retardant. As a new type of energy saving and environment friendly rubber, the EPDM has excellent heat resistance, aging resistance, corrosion resistance and insulation performance, and thus it has been widely used in all walks of life. To this end, EPDM has been used to develop different types of flame retardant materials. Herein, this research will mainly analyze the application performance of different types of EPDM flame retardants and their flame retardant mechanisms, where the research and application of EDPM flame retarder are mainly described from three aspects: intumescent flame retarder, phosphorous flame retarder and inorganic flame retarder
