Introduction
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.
Application
1. Used to prepare many kinds of high-efficiency intumescent coating, the flameproof treatment for wood, multistory building, ships, trains, cables, etc. 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.
