TF- PTS241
Model No.: TF-PTS241
Product introduction
TF-PTS241 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-PTS241 takes effect by char formation and intumescent mechanism. PP with 22% TF-PTS241 can pass the tests of UL94 V-0(3.0mm) and GWIT 960℃.
Features
1. White powder, good water resistance.
2. Low density, low smoke generation.
3. Halogen-free and none heavy metal ions.
Product Usage
TF-PTS241 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.
