Production 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.

Ammonium polyphosphate (Phase II) is a non-halogen flame retardant. It acts as a flame retardant by the intumescence mechanism. When APP-II is exposed to fire or heat, it decomposes to polymeric phosphate acid and ammonia. The polyphosphoric acid reacts with hydroxyl groups to form a nonstable phosphate ester. Following dehydration of the phosphate ester, a carbon foam is built upon the surface and acts as an insulation layer.


The flame retardant PP treated by TF-241 has better water resistance. It still has good flame retardant (UL94-V0) performance after boiling 72 hours in 70℃ water.

PP(3.0-3.2mm) with 22% TF-241 can pass the tests of UL94 V-0 and GWIT 750℃ / GWFI 960℃.

PP (1.5-1.6mm) with 30% addition volume of TF-241 can pass the tests of UL94 V-0.
