Halogen-Free Intumescent Flame Retardant For PP UL94 V-0 GWIT 960℃ Similar Application With AP760 From Clariant
PP with 22% TF-241 can pass the tests of UL94 V-0(3.0mm) and GWIT 960℃.
TF-241 is a white free flowing powder. It is a halogen-free additive flame retardant based on ammonium polyphosphate which develops its effectiveness through phosphorus and nitrogen synergism.
TF-241 differs in its mode of action from chlorine or bromine containing flame retardants by achieving its effect through intumescece. The flame retardanted material foams on exposure to flame. The carbon foam layer so formed protects the polymer through its heat-insulating effect and reduces further oxygen access.
Technical Data Sheet / Specification:
|P2O5 content (w/w)||≥52%|
|N content (w/w)||≥18%|
|Bulk density||0.7-0.9 g/cm3|
|Average particle size ( D50)||about 18µm|
1. White powder, good water resistance.
2. Low density, low smoke generation.
3. Halogen-free and none heavy metal ions.
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.
