1,1'-(isopropylidene)bis[3,5-dibromo-4-(2,3- dibromo-2-methylpropoxy)benzene

1,1'-(isopropylidene)bis[3,5-dibromo-4-(2,3- dibromo-2-methylpropoxy)benzene

1. Product Introduction
Tetrabromobisphenol A bis (dibromomethylpropyl ether) is an additive flame retardant, mainly used as a flame retardant for Appearance wall insulation. It has a significant flame retardant effect in XPS extruded boards and EPS foaming applications. It has the characteristics of low dosage, good flame retardant effect, and little impact on the physical properties of the material. The product has stable quality and extremely high flame retardant efficiency. A very small dosage can achieve excellent flame retardant effects. There is no need to add other auxiliary flame retardants, which meets environmental protection requirements. Compared with traditional flame retardants, it has a lower addition cost.
