Tetrabromobisphenol A (TBBA)
CAS No.: 79－94－7
Molecular Formula: C15H12Br4O2
Application: As a reactive flame retardant, it finds particular application in epoxy, vinyl esters and polycarbonate systems. As an additive flame retardant, it’s widely used in ABS.
Benefits and Features:
It is a highly pure flame retardant containing very stable aromatic bromine. It can be used as a reactive or additive flame retardant. As a reactive flame retardant, it finds particular application as a reactive monomer in epoxy and polycarbonate polymers. It is very cost effective and once reacted, it is permanent and non-migrating, it is a major component in epoxy oligomers used as additives for styrenic polymers and many engineering thermoplastics. Properties of note are improved polymer viscosity and UV resistance. As an additive flame retardant, it is widely used in ABS. It melts blends into these systems, resulting in excellent processability, impact strength and moderate-range UV stability. It is generally used with a synergist such as antimony oxide for maximum flame retardant performance.
