PC/aBS alloys have excellent overall properties. Although the PC itself has a certain flame retardancy (LOI = 25%), the flame retardancy is degraded after blending with aBS. In order to meet the application of PC/aBS alloys in electronics, electrical switches, electrical appliances, etc., flame retardants must be added. Flame retardants commonly used in commercial flame retardant PC/aBS alloys are brominated flame retardants such as brominated epoxy resins, brominated polycarbonates, brominated polystyrene, decabromodiphenylethane; phosphate esters. It is a flame retardant. Such as TPP, RDP, BaPP; phosphorus-bromo structure flame retardant, such as tris(2,4-dibromophenyl phosphate), the trade name is KroitePB--460. Their flame retardant PC/aBS alloys each have their own characteristics.
I System description:
Heat Shrinkable Sleeve with hot melt adhesive, having properties of excellent insulating, environmental sealing, and resistant to impact and abrasion. It is designed for applications to seal and protect electrical splices, cable terminations and joints where electrical insulation and water proof are required. 3:1 shrink ratio allows it easily fit over irregular shape and large connectors.

A comparative test was conducted on the flame retardant used in the flame retardant PC/aBS alloy. The results show that when the PC/aBS mass ratio is 7:3. Adding about 3% of the flame retardant PC/aBS alloy to the bromine-based flame retardant can make the flame retardant performance of the material reach UL-94V-0 (1.6nun); the phosphate ester flame retardant is resistant to aBS The burning effect is not good. Only when the PC mass fraction is more than 70% in the material, the flame retardant effect is obtained: with the bromine monophosphate flame retardant, even if the PC mass fraction of the material is 50%, the uL- can be achieved. 94V-O grade (1.6mm), indicating that phosphorus and bromine have synergistic effect in PC/aBS alloy, and phosphate ester flame retardant is compounded with bromine flame retardant in flame retardant PC/aBS alloy. . There are similar effects.
