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.
Application : Aqueous solution is used for the retardant treatment .To prepare 15-20%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
Can be widely used in water-soluble fire retardant coating, but also used as a high concentration of binary
compound fertilizer, slow release fertilizer, ion-exchange agent and dispersants in mining industry.
