Ammonium Polyphosphate

Molecular formula:(NH4)n+2Pn03n+1
Physical and chemical properties of ammonium polyphosphate: according to degree of polymerization, the ammonium polyphosphate can be divided into low-grade polymer, intermediategrade polymer and high-grade polymer The greater the degree of polymerization is, the lower the water-solubilltx/ wiH be. It can be fallen into crystalline type and amorphous type by structures. Crystal”ine ammonium polyphosphate is water insoluble and long-chain polyphosphates, having five variants ranging from I to V types.

Ammonium polyphosphate: high phosphorus content (P205 IS above 65%). high nitrogen content (above 12%), good heat stability (decomposition temperature≥ 250°C ). High degree of polymerization, low hygroscopicity, the product approaches neuter, has good compatibility with other fire retardants, uniformly dispersed. nontoxic, having good flame-retardant effect.

Application

Ammonium polyphosphate is a excellent additive type flame retardant that can be used not only solely but also with other fire retardants, mainly used as f’ire-retardant paint, as coating for steel parts of high rise bu’ildings, ships, tra’ins indoor and outdoor; used for fireproofing treatment of cables, can also be used for Inflaming retarding of woods, papers and fibers etc, inflaming retarding of various plastics such as PE, PP, PVC …, dry powder fire ext’inguishing in forest and oil field, and finally can be used as fertilizer.
