XS-APPII Ammonium Polyphosphate Series

Ammonium Polyphosphate is a phosphorus-nitrogen compound halogen-free environment-friendly flame retardant. The product is white powder with high phosphorus and nitrogen content, low water solubility, high stability and good flame retardant effect. It can effectively synergize flame retardant with other flame retardants.

Our company has independent ammonium polyphosphate synthesis technology, which has low stability, low viscosity, good dispersibility, low water solubility, and excellent resistance to precipitation and migration. The degree of polymerization is high, and the molecular weight distribution range of high polymerization is concentrated.
