Uses3

  • ComOcBDE /Commercial Octabromodiphenyl Ether/ is predominantly used in acrylonitrile butadiene styrene to flame retard business equipment housings. **PEER REVIEWED**
  • 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. **PEER REVIEWED**
