Introduction of Flame Retardant Brominated Epoxy Resin

In a narrow sense, a flame retardantis a kind of flame retardant additive for polymer materials. It is originally a flammable or combustible polymer material. After adding this flame retardant additive, it can become a flame retardant material. Flame retardant can be divided into There are two types of additive type and reactive type. Additive flame retardants are added in the post-treatment or molding process of polymer materials, and generally do not chemically react with polymer materials, such as octabromoether and antimony trioxide. The typical reactive flame retardant is used as a monomer to participate in the polymerization reaction of polymer materials. For example, in the polymerization reaction of ordinary epoxy resin, the brominated epoxy resin bisphenol A type epoxy end polymerized with tetrabromobisphenol A is used. The bromine content of the brominated epoxy resin flame retardant increases with the increase of the molecular weight, but the increase decreases with the increase of the molecular weight, the minimum is 48.8%, and the maximum limit is 53.3%.

Brominated epoxy resin flame retardants are divided into three categories: low, medium and high molecular weight. Low molecular weight brominated epoxy resin flame retardants are mainly used in epoxy resin flame retardant materials. Medium and high molecular weight brominated epoxy resin flame retardants are mainly used as special flame retardants for engineering plastics.
