Product Description

UL94 V0 PP Flame Retardant With P-N Synergies
Product description: TF-241 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-241 takes effect by char formation and intumescent mechanism.
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.

UL94 V0 halogen free Flame Retardant for PP With P-N Synergies 1

  • Non-halogenated flame retardant based on ammonium polyphosphate, which develops its effectiveness through phosphorus/nitrogen synergism
  • Non-halogenated flame retardant with favorable environmental and health profile
  • When incorporated into thermoplastics, it exhibits high processing stability
  • Differs in its mode of action from chlorine- or bromine-containing flame retardants by achieving its effect through intumescence
  • May be used in polypropylene, PP-copolymers, and PP-blends
  • In compounding a reduced water uptake, less contamination of the water bath and less soapiness of the polymer strength is observed
  • Low smoke density and low smoke gas corrosivity
  • Excellent UV stability
  • Good recyclability
