Chemicals - BUTADIENE

Butadiene, also known as 1,3-butadiene, is a colourless gas that condenses to a liquid at minus 40.10F/4.50C. Butadiene is derived, using an extractive distillation process, from the crude C4 stream, one of the cracker by-products of ethylene and propylene production.

The largest single use for butadiene is in the production of styrene-butadiene rubber (SBR) which, in turn, is principally used in the manufacture of automobile tyres. SBR is also used in adhesives, sealants, coatings and in rubber articles like shoe soles.

Polybutadiene is also used in tyres and can be used as an intermediate in the production of acrylonitrile-butadiene-styrene (ABS). ABS is widely used in items such as telephones, computer casings and other appliances. Other polymers made from butadiene include styrene-butadiene latex, used for example in carpet backings and adhesives; nitrile rubber, used in hoses, fuel lines, gasket seals, gloves and footwear; and styrene-butadiene block copolymers which are used in many end-uses ranging from asphalt modifiers (road and roofing construction applications), to adhesives, footwear and toys. Chemical intermediates made from butadiene include adiponitrile and chloroprene which are used, respectively, in the manufacture of nylon and neoprene.
