溴化聚苯乙烯基溴的

Brominated Polystyrene (BPS) is my company developed a new type of brominated flame retardants, polystyrene (PS) under the action of the catalyst by bromide, smashing a light yellow powder made of solid. Physical Properties: The product is white / yellow powder or granules, with good chemical stability and thermal stability. This product is insoluble and water, alcohol, ether, dichloroethane, etc., dissolved in tetrahydrofuran, bromine chloride. As the polystyrene (PS) is a kind of engineering plastics, the mechanical properties of the material less than 90% could be retained mechanical properties.

Application: BPS application and flame-retardant PBT, PET, PC, PA and some of their alloys, in particular, the above glass fiber reinforced plastic, also applies to the flame retardant polyolefin, especially for filled nylon.
