TF303, TF304 is a kind of water soluble flame retardant of ammonium polyphosphate. It features halogen free, eco-environmentally friendly, 100% water soluble. After spray and soaking treatment, the fireproof performance could achieve the effect of extinguishing the fire. It is widely used in the wood, paper, bamboo fibers, extinguisher’s fireproof treatment.1.Aqueous solution is used for the retardant treatment .To prepare 15-25%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.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.
