Fire retardant cleaner, flame retardant, powder extinguish agent, high temperature adhesive. It can also prepare ammonium polyphosphate intermediate.
Ammonium polyphosphate with the decomposition temperature more than 200℃ is a widely used flame retardant. After the treatment of urea phosphate aqueous solution, the wood laminate doesn’t deform, the surface of wood products won’t fire when the temperature is in 210℃. Meanwhile, it doesn’t affect the adhesive strength between laminates. It can be used for the fire retardant treatment of wood fiber products, cotton fiber products and resins. In addition, it can also be used to produce refractory coatings, fireproof cleaning agents and granular fire extinguishing agents.
The urea phosphate most commonly sold in the market is urea phosphate 17-44-0. Its maximum moisture percent by weight is 0.02. The minimum total nitrogen percent by weight is 17 and the minimum water soluble phosphorus percent by weight is 44.
