APP Flame Retardant - EPFR-APP224



PreniphorEPFR-APP224 is a kind of crystal type Ⅱ APP flame retardant, which has high polymerization degree, but without encapsulated and activated. It has high content of phosphorus & nitrogen, excellent thermal stability, near-neutral and non-toxic smoke property. It takes effect by char formation and intumescent mechanism. 


EPFR-APP224 can meet the requirements of different applications. It is highly recommended to intumescent coating.


Compared with other similar commercial products, at the same dosage, EPFR-APP224 has much lower viscosity in water, polyol suspension of polyurethane and better stability for long term storage. Compared with EPFR-APP222H, it has bigger particle size.
