Ammonium Polyphosphate Phase II,
25kg Low Smoke Ammonium Polyphosphate
PU Sealer for Wood Fireproof, Intumescent Flame Retardant, Low Smoke Production
Description of Product
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.
2. used as the main flameproof additive for expanding-type flame retardant used in plastic, resin, rubber, etc.
3. make into powder extinguishing agent to be used in large-area outfire for forest, oil field and coal field, etc.4. In plastics(PP, PE, etc. ), Polyester, Rubber, and Expandable fireproof coatings.5. used for textile coatings.
