Application:
Brominated polystyrene is a brominated organic flame retardant, widely used in engineering plastics such as polybutylene terephthalate, polyethylene terephthalate, polyphenylene ether, nylon-66, etc.
Brominated polystyrene is mainly used in thermoplastic resins such as PA, PBT, PET, etc., and it needs to be used in conjunction with antimony compounds. In the case of flame retardant polyester, the addition amount of 10% (reinforced) to 17% (non-reinforced) can be assigned to the material UL94V-O grade (0.8mm). Material UL94V-O grade (0.8mm).
Brominated polystyrene is made of polystyrene by bromination and is mainly used as a flame retardant in engineering plastics. Since polystyrene (PS) is an engineering plastic, BPS has good compatibility with engineering plastics. It has the least impact on the mechanical properties of the material, and can guarantee more than 90% of the mechanical properties.
