数据库记载的用途

  • 1,3-Butadiene is used in the production of rubber and plastics. It is also used in copolymers including acrylics.
  • Used in the production of synthetic rubber for motor vehicle tires; also used in styrene-butadiene polymers, acrylonitrile-butadiene-styrene resins, and other compounds; [ACGIH] In a study of Swedish refinery workers, The exposure to 1,3-butadiene among all exposure groups was low (95% of all samples were below 10 ug/m3) in relation to the Swedish OEL, of 1000 ug/m3.

  • Plastic Composites Manufacturing [Category: Industry]
  • Smoking cigarettes [Category: Food & Drugs]
  • The majority of the butadiene produced worldwide is used as a monomer or co-monomer in the manufacture of synthetic rubber, above all for styrene - butadiene rubber and latex (SBR), polybutadiene rubber (BR), acrylonitrile - butadiene rubber and latex (NBR), and for chloroprene rubber (CR). Important plastics containing butadiene as a monomer component are impact-resistant polystyrene, a two-phase system consisting of polystyrene and polybutadiene; ABS polymers, consisting of acrylonitrile, butadiene, and styrene;
