Product Description:
Ammonium polyphosphate (APP) is a kind of efficient halogen-free flame retardant, according to their degree of polymerization can be divided into low, and has three kinds of poly. Ammonium polyphosphate is nontoxic and tasteless, does not release corrosion gas, has small hygroscopicity, and has high thermal stability. Coated ammonium polyphosphate (APP-M1/M2) can further improve the stability of products, reduce the moisture absorption performance of products, and improve the compatibility of flame retardants and matrix resins.
