Halogen-free flame retardant APP(Ⅱ)HF-P2000

Ammonium polyphosphate HF-APP (Ⅱ) is a series of phosphorus-nitrogen based intumescent inorganic flame retardants. Among them, HF-P2000 is a high-polymerization crystalline type II ammonium polyphosphate product that has not been activated or coated. It is also the most basic product and can meet most application fields. Especially recommended for intumescent coatings

Introduction: Ammonium polyphosphate HF-APP (Ⅱ) is a series of phosphorus-nitrogen based intumescent inorganic flame retardants. Among them, HF-P2000 is a high degree of polymerization crystalline type II ammonium polyphosphate product that has not been activated or coated. This product has high content of P and N flame retardant elements, good thermal stability, almost neutral, non-toxic and low smoke. Combined with other gas sources and carbon sources, it plays the role of flame retardant and fire prevention through the mechanism of char formation and expansion. (Flame retardants for fabric coatings)

Application: HF-P2000 is a non-melamine-modified HF-APP (II) product. HF-P2000 is also the most basic product and can meet most application fields. Especially recommended for intumescent coatings.

Advantages: good thermal stability; low viscosity and good dispersion; low water solubility, good resistance to precipitation and migration; high degree of polymerization (n ≥ 1000), narrow molecular weight distribution range, and extremely low content of small molecule substances such as oligomers; Type II structural purity is high; excellent particle size distribution.
