Product Description:
Tetrabromobisphenol A bis(dibromopropyl ether), often abbreviated as TBBPA-DBPE, is a brominated flame retardant (BFR). It is a complex molecule characterized by a high bromine content, which contributes to its effectiveness in inhibiting combustion in various polymeric materials. This additive flame retardant is typically a white or off-white powder. It is incorporated into plastics and resins to reduce their flammability and delay the spread of fire, thereby enhancing the safety of products in applications such as electronics, construction materials, and textiles. Due to its chemical structure, it offers good thermal stability and compatibility with a range of polymers.
