PC/ABS alloy with excellent comprehensive performance. Although have certain flame retardant PC itself (LOI = 25%), but with ABS blend, flame retardant performance degradation. For PC/ABS alloy in the field of electronics, electrical switches, electrical and other applications, you must add flame retardant. Commercialization of the flame retardant PC/ABS alloy that is commonly used in flame retardant with bromine flame retardants, such as brominated epoxy resin, polycarbonate bromide, brominated polystyrene, ten bromine diphenyl oxide; Phosphate ester flame retardants. Such as the TPP, RDP, BAPP; P a structure of bromine flame retardants, such as phosphate (2, 4 two bromine phenyl ester), trade names for KroitePB - 460. They flame retardant PC/ABS alloy have their characteristics.

The flame retardant PC/ABS alloy compares the flame retardants used in the experiment. Results show that when the PC/ABS quality ratio of 7:3. Add flame retardant PC/ABS alloy about l3 % of the amount of bromine flame retardants, can make the material of the flame retardant performance achieved UL - 94 - v - a level 0 (1.6 nun); Phosphate ester flame retardants for ABS flame retardant effect is not good, only in the material PC when the mass fraction is more than 70%, is flame retardant effect: with a phosphate bromide flame retardants jing, even in the material PC when the mass fraction of 50%, also can achieve uL - 94 - v - O level (1.6 mm), phosphorus and bromine in PC/ABS alloy has the association effect, phosphate flame retardants and bromine series flame retardant JingFu with use, in the flame retardant PC/ABS alloy. Also have a similar effect.
