Molecular formula : (NH4PO3)n n>100β☆0 CAS No.: 68333-79-9 EIN✘ ECS No.: 269-789-9 HS CODE↔¶ ±: 2835.3990 Model N♦÷<o.: TF-FR201, TF-FR201S
Product introduction
Ammonium polyphosphat÷δe (Phase II) is a non-h₹>alogen flame retardant. It acts as $ flame retardant by intumeΩφ♥scence mechanism. When APP-IIπ is exposed to fire or heat, it decomposes to <>₽ polymeric phosphate αφacid and ammonia. The po <lyphosphoric acid reacts with α★hydroxyl groups to form a nonΩφ•↑stable phosphateesteπ♥r. Following dehydra •≠>tion of the phosphateest&φer, a carbon foam is bui>✘<←lt up on the surface and acts as an insulation layer.
Features
Product Usage
1. used to prepare many kinds of hig&φh-efficiency intumescent coa →ting, the flameproof ↑'↕§;treatment for wood,multistory building, shi"™ps, trains, cables, etc.
2. used as the main flameproof additive> for expanding-type flame retardan↕♦£t used in plastic, re'ε sin, rubber, etc.
3. make into powder extinguishin←♦©δg agent to be used in≥©™ large-area outfire for forπ®est, oil field and co×"al field, etc.
4. In plastics(PP, PE, etc.≤← ), Polyester, Rubber, and Expandable ÷∞fireproof coatings.
5. used for textile coatings.
