◉ Introduction of Hexabromocyclododecane
Hexabromocyclododecane, abbreviated as HBCD or HBCDD, is a white crystal. It is an alicyclic hydrocarbon compound with high bromine content. The molecular formula is C12H18Br6. It belongs to persistent organic pollutants (POPs for short) and is a chemical substance synthesized by humans. Exist in the environment, accumulate through the biological food chain (bioaccumulation), and then cause harm to the environment and human health. The harm to humans is mainly manifested in persistence, long-distance migration and bioaccumulation.
HBCDD has poor thermal stability and good UV light stability. HBr begins to decompose at 150°C, and the dehydrobromide reaction becomes intense at 190°C. The melting point is usually between 175 and 195 °C, the low melting point type is 167-168 °C, and the high melting point type is 195-196 °C. The solubility of HBCDD in water is extremely low, and the solubility at 20℃ is 65.6μg/L. Soluble in methanol, ethanol, acetone, amyl acetate and other organic solvents. The main use is as a flame retardant.
◉ The Main Purpose
Hexabromocyclododecane is a highly brominated alicyclic additive flame retardant, the third largest brominated flame retardant in the world after polybrominated diphenyl ethers (PBDEs) and tetrabromobisphenol A (TBBPA). Very effective in preventing plastics and textiles from catching fire. It has the characteristics of low dosage, good flame retardant effect and little impact on the physical properties of materials. It is mainly used for flame retardant polypropylene plastics and fibers, and polystyrene foam plastics. Flame retardant of the face leather. Used as additive flame retardant, suitable for polystyrene, unsaturated polyester, polycarbonate, polypropylene, synthetic rubber, etc.
