Ammonium Polyphosphate for Expanding-type Flameproof Coating (Crystal Phase II)
CAS NO. 68333-79-9
Packaging & Delivery
Packaging Detail: Securely enclosed in compound kraft paper bags with an inner PE lining, each bag weighs a net 25 kilograms, or as per customer's specifications.
Delivery Detail: Swift shipment, dispatched within 6 days upon receipt of deposit.
Character:
1. Enriched with a high concentration of phosphorus and nitrogen, ensuring superior flame-retardant efficiency.
2. Exhibits high polymerization degree with minimal water solubility and hygroscopicity.
3. Maintains a nearly neutral pH value, offering excellent thermal stability and compatibility.
Usage:
1. Ideal for formulating diverse high-efficiency expanding-type flameproof coatings, suitable for multi-story structures, marine vessels, trains, and cabling.
2. Effective in the flameproof treatment of wood, plywood, fiberboard, paper, and textiles.
3. Serves as a primary flameproof additive for expanding-type flame retardants used in plastics, resins, and rubber.
4. Can be processed into a powdered extinguishing agent for large-scale firefighting applications in forests, oil fields, and coal mines.
