Molecular formula : (NH4)n+2PnO3n+1 n<20 CAS No.: 68333-79-9 EINECS No.: 269-789-9 HS CODE: 2835.3990 Model No.: TF-301 , 302
Product introduction
Other name: polyphosphoric acids, ammonium salts Properties: Ammonium polyphosphate with short chain and low polymerization degree, PH value is neutral. Appearance : White powder or lumps, easy to absorb water and good solubility. The water solution is clear.
Features
1. Lump solid, stable property, convenient for transportation, storage and use ;
2. pH value is neutral, safe and stable during production and use, good compatibleness, not to react with other flame retardant and auxiliary ;
3. High P-N content, appropriate proportion, excellent synergistic effect and reasonable price.
Product Usage
1. Aqueous solution is used for the retardant treatment .To prepare 20-25%P-N flame retardant, used solely or together with other materials in the flameproof treatment for textiles, papers, fibers and woods, etc. To apply by autoclave, immersion or by spray both ok. If special treatment, it can be used to prepare high-concentration flameproof liquid to 50% to meet the flameproof requirement of special production.
2. It also can be used as flame retardant in water based fire extinguisher and wood varnish,
3. It is also used as a high concentration of binary compound fertilizer, slow released fertilizer.
