EPFR-400A
Preniphor™ EPFR-400 series mainly function in condensed phase.
Flame retarding mechanism of Preniphor™ EPFR-400 series in TPE: under high temperature, acidic materials are decomposed then catalye benzene ring and and other groups of polyphenylene ether in TPE to form carbon layer through dehydration and carbonization. At the same time, non-combustible gases are generated from the decomposition of MCA and other components to make the carbon layer expansive, to isolate the materials from air.
