Halogen Free Ammonium Polyphosphate Flame Retardant APP(Ⅱ)HF-P3001S with High Polymerization ≥1000 and Low Water Solubility

HF-P3001S is a silane-treated high-polymerization crystalline type II Ammonium Polyphosphate flame retardant. This advanced formulation features high phosphorus and nitrogen content, excellent thermal stability, near-neutral pH, non-toxic properties, and low smoke emission.

When combined with gas sources and carbon sources, this product provides effective flame retardant and fireproof protection through carbonization and expansion mechanisms, creating a protective char layer that inhibits flame spread.

• Low viscosity with excellent dispersibility for easy processing
• Minimal water solubility with superior resistance to precipitation and migration
• High degree of polymerization (n ≥ 1000) with narrow molecular weight distribution
• Extremely low content of oligomers and small molecules
