Crystalline II ammonium polyphosphate
The benefits of our APP801:
1. Halogen and formaldehyde-free, non-toxic and does not generate additional
quantities of smoke.
2. High polymerization degree ("n" value > 1000), higher thermal stability and lower
water solubility than APP-I.
Applications:
1. Used to prepare many types of high-efficiency intumescent paint & coatings for
the flameproof treatment of multi-story buildings, ships, trains, cables, etc.
2. Used as the main flameproof additive for expanding-type flame retardants used in
plastics, resin, rubber, etc.
3. Used in plastics (PP, PE, PVC, etc.), polyester, rubber, expandable fireproof
coatings.
4. Flameproof treatment for woods, plywood, fiberboard, papers, and fibers.
5. Can be used for PU applications (thermosets) and PU foam (rigid and/or flexible)
