Eco-Friendly Halogen Free Flame Retardant For PP Good Water Tesistance
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 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.

Characteristics :
1. White powder, good water resistance.
2. Low density, low smoke generation.
3. Halogen-free and none heavy metal ions.
Application:
TF-241 is used in homopolymerization PP-H and copolymerization PP-B . It is widely used in
flame retardant polyolefin like steam air heater and household appliances.
