TF- PTS241
Model No.: TF-PTS241
Product introduction
TF-PTS241 mainly contains P≤₩§ and N, is a kind of halogen free e→€nvironmentally friendly flame retardant←δ for polyolefin. It has been develπ∑oped especially for vaφ≥rious PP. Containing acid source, gaλs source and carbon ¥δsource, TF-PTS241 takes e'×'ffect by char formation and intumes ×cent mechanism. PP wit≥↓h 22% TF-PTS241 can pass the t§βests of UL94 V-0(3.0mm)✔ and GWIT 960℃.
Features
1. White powder, good wa™£©£ter resistance.
2. Low density, low smoke genera✔"← tion.
3. Halogen-free and none hea☆∏™&vy metal ions.
Product Usage
TF-PTS241 is used in homopolymerization PP-H and copo↓$lymerization PP-B . It is widely used i÷₩n
flame retardant polyolefin l ↔φ®ike steam air heater ♠↕λ and household appliances.
