CAS No.:17675-60-4

Molecular Formula:C2H9N4O5P

Molecular weight: 200.09

Application:

flame retardant of paper, textile, wood, polyurethane, etc.
Guanylurea phosphate are widely used in intumescent fire-retardant coatings, polyethylene, polypropylene, polyurethane, epoxy resin, rubber products, fiberboard, plywood, textiles, paper (can be used for insulating paper) and dry powder fire extinguishing agents, etc. It is a safe and efficient phosphate non halogen smoke elimination flame retardant.

Guanylurea phosphate has high flame retardancy, dimensional stability, hydrolysis resistance, and heat resistance in polyurethane rigid foams. The amount of toxic and corrosive gases generated in rigid polyurethane foams is also much lower than that of halogen-containing polyurethane foams. 

Guanylurea phosphate has the function of expansion and flame retardant, so it is more conducive to reducing smoke and resisting dropping. Although it is solid, it is easy to disperse in polyols.
