Hopeflam EDPO

EDPO (1,2-Bis(diphenylphosphinoyl)ethane, CAS 4141-50-8) is a halogen-free phosphine oxide flame retardant. It has high phosphorus content, excellent thermal stability and good compatibility with epoxy resin systems. It works in both gas phase and condensed phase, delivers high flame retardant efficiency with low loading. It has little negative impact on mechanical and electrical properties of cured epoxy. Mainly used for epoxy resin, copper clad laminate (CCL), electronic packaging, composite materials and high-performance electronic components to achieve UL94 V-0.
