Tetrabromobisphenol A Bis(dibromopropyl Ether)

CAS 21850-44-2

Octabromoether, molecular formula c21h20o2br8, molecular weight 934.26, melting point about 105 ℃, soluble in benzene, acetone, chloroform, etc., insoluble in water hexanol, decomposition temperature 270 ℃, is the main product of further processing of tetrabromobisphenol A, with better flame retardant effect. It belongs to additive flame retardant in polymer flame retardant, and is often used in flame retardant of polypropylene (PP), polyethylene (PE), polybutene and many polyolefin copolymers. Its molecular structure contains aliphatic bromine and aromatic bromine. It has high flame-retardant efficiency, can withstand high processing temperature, can melt blend with polyolefin, and has appropriate thermal stability, low price and efficiency. When comparing the flame-retardant PP with the non flame retardant PP blank sample, it was found that there was almost no difference in mechanical properties between them. In the combustion products of this product, the carcinogens tetrabromodibenzodiane and tetrabromodibenzofuran can hardly be detected. The results show that compared with the traditional flame retardant decabromodiphenyl ether, when it reaches the same flame retardant level, the amount of this product is less. Compared with hexabromocyclododecane, the decomposition temperature is higher, and in some aspects, hexabromocyclododecane can not be replaced. The flame retardant effect of octabromoether is very good, which is one of the development directions of bromine series flame retardants, and its application prospect is very broad.
