数据库记载的用途

• Used as additive flame retardant; [HSDB] Used as flame retardant additive for polymers (mainly acrylonitrile-butadiene-styrene); Use is severely restricted in the EU; [eChemPortal: ESIS]
• The commercial octaBDE is used by the plastics industry as an additive flame retardant for manufactured products. It is used almost exclusively to flame retard acrylonitrile-butadiene-styrene (ABS) terpolymers used in computer casings and monitors ... Other minor uses ... include high impact polystyrene (HIPS), polybutylene terephthalate (PBT), and polyamide polymers.
• ComOcBDE /Commercial Octabromodiphenyl Ether/ is predominantly used in acrylonitrile butadiene styrene to flame retard business equipment housings.
• Polybrominated diphenyl ethers (PBDEs) are flame-retardant man-made chemicals found in plastics used in a variety of consumer products to make them difficult to burn. Octabromodiphenyl ethers are used in conjunction with antimony trioxide as a flame retardant in the housings of electrical and electronic equipment, mainly in the plastic acrylonitrile butadiene styrene, but also in high impact polystyrene, polybutylene terephthalate and polyamides. (L628, L701)
• Octabromodiphenyl ether is synthesized by treating diphenyl ether with 8 equivalents of Br2 in the presence of Al2Cl6/A12Br6, first at 35 °C and then at 120 °C. /Commercial OBDE is a mixture of approximately 11% PeBDE/HxBDE, 44% HpBDE, 31-35% OBDE, 10% NBDE, and 0.5% DeBDE. On the basis of the chemical structure, there are 12 possible isomers of OBDE./
• Benzene, 1,1'-oxybis-, octabromo is listed as a High Production Volume (HPV) chemical (65FR81686). Chemicals listed as HPV were produced in or imported into the U.S. in >1 million pounds in 1990 and/or 1994. The HPV list is based on the 1990 Inventory Update Rule. (IUR) (40 CFR part 710 subpart B; 51FR21438).
