CAS No.: 68333-79-9

Molecular Formula： (NH4PO3)n n>1000, n = degree of polymerization

Specification: APP Phrase-II (n>1000, P2O5>71%, N%>14%)

Properties：White Powder, APP II structure is cross linked. The molecular weight is much higher than APP I with "n" value higher than 1000. APP II has a higher thermal stability (decomposition starts at approximately 300°C ) and lower water solubility than APP I.

Application：As a fire retardant in plastic (PP, PE, PVC, ect.), Polyester, Rubber, and Expandable fireproof coatings.
