Description

2,3,3',4,4'5,6-Heptabromobiphenyl CAS NO 79682-25-0 is a highly brominated derivative of biphenyl, belonging to the class of polybrominated biphenyls (PBBs). This compound is valued for its high bromine content, which imparts significant flame-retardant properties, making it a critical component in enhancing fire safety in various industrial materials. It is primarily sought by manufacturers in the polymer, electronics, and construction material sectors who require advanced halogenated flame retardants. Our supply ensures high purity and batch-to-batch consistency to meet stringent formulation requirements.

Application

• As a flame retardant additive in engineering thermoplastics such as ABS, polycarbonate, and PBT.
• In the formulation of fire-resistant coatings and paints for construction materials and textiles.
• For enhancing the fire safety of electronic components and circuit boards.
• As a reactive intermediate or additive in the synthesis of specialty polymers with inherent flame-retardant characteristics.
• In research and development for studying the environmental fate and toxicology of brominated compounds.
• Potential use in cable insulation and wiring materials to meet industry safety standards.
