Organic aluminum salt flame retardant containing phosphorus is white powder with high hydrophobicity, high temperature resistance and non-migration. It is mainly applied to engineering plastics such as PET, PBT (glass fiber reinforced and unreinforced) . It has excellent flame retardant efficiency with nitrogenous flame retardants. a.8003 especially can be applied to PBT, PET. It suits glass fiber reinforced PBT, PET and unreinforced PBT, PET. Flame retardant PBT and PET show good physical and electrical properties. b.Glass fiber reinforced PBT products usually can reach flame retardant requirement UL94 V-0 (thickness of 1.6mm) with adding 13-16% (by weight) 8003 and additional nitrogenous flame retardants in it.
