Brominated polystyrene is a kind of novel brominated flame-retardants developed by our company. it has stability in high terperature.under the temperature of 300,if it is mixed with suitable synergistic agent, the nature color of bedding materials can be kept,the compatibility with engineering plastic being good, with no separation,no transference and no frost on the surface. an excellent antistatic properties. the influence towards the mechanic performance of  material is small,which can retain more than 90%mechanics performance.Which is brominated from polystyrene with catalyst, and then forms light yellowish powder after crushed.

CAS NO.: 88497-56-7 Chemical formula: (C8H5.3Br2.7)n

Physical property:

the products is white/yellowish powder/particle. Its has outstanding thermal stability and chemical stability, it dissolve in tetrahydrofuran and bromochloromethane, but it does not dissolve in water, alcohol, ether and ethylidene dichloride.
