TF-241 is a Phosphorus-nitrogen flame retardant. When the polymer containing this kind of flame retardant is heated, a uniform carbon foam layer can be formed on the surface, which can provide heat insulation, oxygen insulation and smoke suppression. It has good flame-retardant properties and prevents the phenomenon of dripping. Intumescent flame retardant systems generally consist of three parts: acid source (dehydrating agent), carbon source (carburizing agent) and gas source (nitrogen source, foaming source). Intumescent flame retardants play a flame retardant role in the cohesive phase mainly by forming a porous carbon foam layer. Phosphorus-nitrogen flame retardants have the advantages of halogen-free, low smoke and low toxicity.

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.
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.
