Product description


Op1311 is an environmentally friendly halogen-free flame retardant in phosphorus and nitrogen system. This flame retardant is a white powder, organic hypo - phosphonate. The product is moisture-proof and insoluble in water and acetone, dichloromethane, butanone, toluene and other organic solvents. The polymer with ADP added to form the expanded carbon layer during the combustion process, so as to achieve the effect of heat insulation, oxygen isolation and prevent the further diffusion of the surface flame, and play a role of fire protection and flame retardancy. The flame retardant does not hydrolyze, does not precipitate, and has good carbon self extinguishing.
