Ammonium polyphosphate(phase-ii) (cf-app201) Molecular formula : (nh4po3)n n>1000 Cas no.: 68333-79-9 Einecs no.: 269-789-9 Model no.: cf-app201 Ammonium polyphosphate(phase ii) is a non-halogen flame retardant. It acts as flame retardant by intumescence mechanism. When app-ii is exposed to fire or heat, it decomposes to polymeric phosphate acid and ammonia. The polyphosphoric acid reacts with hydroxyl groups to form a nonstable phosphateester. Following dehydration of the phosphateester, a carbon foam is built up on the surface and acts as an insulation layer. Use : In plastics(pp, pvc, pe, etc. ), polyester, rubber, and expandable fireproof coatings. Packing : 25kg woven bag with plastic liner. 25kg woven bag with plastic liner.

It is a nitrogen containing halogen-free environmentally friendly flame retardant, which is a type II polyphosphate. This product has a high degree of polymerization, good thermal stability, low moisture absorption, and low addition amount, can help reducing costs. It is different from halogenated flame retardants. During the combustion process, the product expands the carbon layer to achieve heat insulation and air isolation, to achieve the flame retardant effect. It is low smoke, low toxicity, and no melting droplets. It is an efficient inorganic environmentally friendly flame retardant material. The pH value is close to neutral, without corrosion to production equipment, reducing equipment maintenance costs. It can work synergistically with aluminum hydroxide, resulting in better results Type II polyphosphate has a wide range of applications, including fireproof coatings for buildings, ships, trains, and cables. It is also the main raw material for compounding flame retardants such as plastics and rubber. It is also suitable for materials such as plastics (PP, PE, PVC, etc.), polyester, rubber, and various high-end intumescent fireproof coatings.
