Properties of Octabromoether CAS 21850-44-2

Octabromoether is soluble in benzene, acetone, chloroform, etc., but is insoluble in hydrohexanol, and has a decomposition temperature of 270°C. It is the main product of tetrabromobisphenol A deep processing and has a better flame retardant effect. In the polymer flame retardant, it is an additive flame retardant, and is often used for the flame retardant of polypropylene (PP), polyethylene (PE), polybutene and many polyolefin copolymers. Its molecular structure contains aliphatic bromine and aromatic bromine, has high flame retardant efficiency, can withstand higher processing temperatures, can be melt blended with the above-mentioned polyolefins, has appropriate thermal stability, and has relatively low price and efficiency.
