Product Description

Halogen Free Flame Retardant Agent Ammonium Polyphosphate TF- 241

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.

Advantage:
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 70ºC water.
PP(3.0-3.2mm) with 22% TF-241 can pass the tests of UL94 V-0 and GWIT 750ºC / GWFI 960ºC.
PP (1.5-1.6mm) with 30% addition volume of TF-241 can pass the tests of UL94 V-0.

Technical Data Sheet / Specification:
