A high efficient halogen-free flame retardant. It is tasteless, non-toxic, with no corrosive gases and high heat stability. Can be used in intumescent coatings, PE, PP, PU, Epoxy resins, Rubber products, fiber boards, and dry powder fire extinguishing agents.
Produced via a special processing method and surface modified based on standard Ammonium polyphosphate (Phase II).
Because of this special treatment, APP-II-W can exhibit improved water resistance, thermal stability, and also compatibility in PP – compared to that of standard Ammonium polyphosphate (Phase II).
For PP, CM-APP-II-W can achieve UL94V-0 rating in both unfilled and glass filled PP.
