Product Description

White Powder Ammonium Polyphosphate Flame Retardant PP Flame Retardant Additive


Product description: TF-241 mainly contains P and N, is a kind of halogen free environmentally friendly flame retardant for polyolefin. It has been developed especially for various PP. Containing acid source, gas source and carbon source, TF-241 takes effect by char formation and intumescent mechanism.


TF-241 differs in its mode of action from chlorine or bromine containing flame retardants by achieving its effect through intumescece. The flame retardanted material foams on exposure to flame. The carbon foam layer so formed protects the polymer through its heat-insulating effect and reduces further oxygen access.
