Halogen-Free PP Flame Retardant For UL94-V0


TF-241 mainly contains P and N, is a kind of halogen-free environmentally friendly flame retardant for polyolefin. It has been developed specially for various PP. Containing acid source, gas source, and carbon source, TF-241 takes effect by char formation and intumescent mechanism. PP with 22% TF-241 can pass the tests of UL94 V-0(3.0mm) and GWIT 960℃.



TF-241 is used in homopolymerization PP-H and copolymerization PP-B. It is widely used in

flame retardant polyolefins like steam air heater and household appliances.
