Flame Retardants

T-3B Antimony Replacement Flame Retardant Masterbatch

T-3B is an antimony composite flame retardant masterbatch engineered to replace antimony trioxide in halogen-containing flame-retardant systems. It uses advanced activation and particle-engineering technology to deliver high whiteness, strong thermal resistance, and fine dispersion. T-3B maintains equivalent flame-retardant performance to ATO while reducing material cost and improving processing safety. It works across a wide range of polymers including PA, PBT, PP, PE, ABS, HIPS, PVC, and rubber compounds.
