88497-56-7
Product name: Brominated Polystyrene
English alias: BPS; Polybromostyrene.
CAS: 88497-56-7
Molecular formula: (C10H13Br)n
Appearance: Off-white particle
Package: 25kg/bag
Brominated Polystyrene is a high molecular weight polymeric flame retardant produced by bromination of polystyrene. This additive-type flame retardant offers excellent thermal stability, high bromine content, and good compatibility with various engineering plastics. Unlike some small molecule brominated flame retardants, BPS does not migrate or bloom to the surface, making it particularly valuable for applications requiring long-term stability and reliability. Its polymeric nature ensures minimal impact on the physical and mechanical properties of the host polymer while providing effective flame retardancy.

Brominated Polystyrene is considered to have low toxicity and good environmental profile compared to small molecule brominated flame retardants. It shows no evidence of bioaccumulation and has low water solubility. However, as with all fine powders, inhalation should be avoided. Use appropriate personal protective equipment including dust mask and safety glasses during handling. The product is stable under normal conditions but may decompose at high temperatures releasing hydrogen bromide.
keep the product dry
relative humidity < 50%
protect product against influences of weather and contamination
Brominated Polystyrene for technical applications is solely supplied in packaging of different sizes . It can be packaged in various items: 25 kg bags, 1000 kg bags.
