1. Halogen-free and none heavy metal ions. 2. Low density, low smoke generation. 2. White powder, good water resistance, can pass 70℃, 168h immersion test. 3. High thermal stability, good processing performance, no obvious water slip during processing. 4. Small addition amount, high flame retardant efficiency, more than 22% can pass UL94V-0 (3.2mm). 5. Flame-retardant products have good performance of high temperature resistance and can pass GWIT 750℃ and GWFI 960℃ tests. 7. Biodegradable into phosphorus and nitrogen compounds.TF-241 is used in homopolymerization PP-H and copolymerization PP-B and HDPE . It is widely used in flame retardant polyolefin and HDPE like steam air heater and household appliances.
