Ammonium polyphosphate(Phase II) is a non-halogen flame retardant with our special technics.,It has particular properties: more fine particle, lower viscosity in solution(water and polyols).It is mostly used as flame retardant for intumescent paints(water and solvent based) and acrylate latex. It is also suitable in textile coating system.
