Product introduction

Ammonium polyphosphate (Ph>Ω↓ ase II) is a non-halogen flame retardaα± nt. It acts as flame retardant by int $£umescence mechanism. When APP-II i→↓s exposed to fire or heat, it dec ♦Ω​omposes to polymeric phosphate★₩β acid and ammonia. The polyphosphoricφαφ acid reacts with hydroxyl groups t•∞o form a nonstable phosphateester. Fo₹♥ ₽llowing dehydration of the​© phosphateester, a carbo₽±✘£n foam is built up on the surface a&₹nd acts as an insulation layer.

Features

Product Usage

1. used to prepare many k£ ∞≈inds of high-efficiency intum÷>'escent coating, the flameproof ∏ ε×;treatment for wood, multistory building, ships, <≠  trains, cables, etc.
2. used as the main flamepα roof additive for expanding-type fl∏​©​ame retardant used in plastic, resin,πσ rubber, etc.
3. make into powder extinguish↓€↔™ing agent to be used in large-area ‌∞÷outfire for forest, oil fieldΩ©↔✘ and coal field, etc.

4. In plastics(PP, PE, etc. ), ₽✘Polyester, Rubber, and E •xpandable fireproof coatings.

5. used for textile coatings.★ ™₹
