Description

1,2,5,6,9,10-hexabromocyclododecane is a bromoalkane consisting of cyclododecane bearing six bromo substituents at positions 1, 2, 5, 6, 9 and 10. It has a role as a neurotoxin, a persistent organic pollutant and a xenobiotic. It is a bromoalkane, a bromohydrocarbon and a brominated flame retardant. 1,2,5,6,9,10-Hexabromocyclododecane(HBCD) is a brominated flame retardant. It is used in the textile industry and polystyrene foam manufacturing. Electrochemical reduction of HBCD at carbon and silver cathodes has been studied using cyclic voltammetry and controlled-potential electrolysis.

Application

1. It can be used in smoldering, for polystyrene foamed plastics, polypropylene and polyester, acrylic, polypropylene and other fabrics as smoldering finishing agent.
2. It is mainly used for thermoplastic and thermosetting polymers which have fire retardant requirements. It is particularly suitable for extrusion of foaming polystyrene.
3. It is used for the fire-retardant polystyrene of polypropylene plastics and fibers. It can also be used for the fire retardancy of finishing and leather double-sided coat after the fire-retardancy of polyester fabric. When used as additive fire retardants, it is especially suitable for polystyrene, unsaturated polyester, polycarbonate, polypropylene, synthetic rubber or the like.
