1,3-butadiene is a colorless, non-corrosive gas or liquid with a mild aromatic or gasoline-like odor. It originates from the high temperature cracking of petroleum fractions and is distilled out of Crude C4’s.
Butadiene is used primarily as a chemical intermediate and as a monomer in the manufacture of polymers such as synthetic rubbers or elastomers, including styrene-butadiene rubber (SBR), polybutadiene rubber (PBR), polychloroprene (Neoprene), and nitrile rubber (NR). In turn, these rubbers and their latexes are used to produce other goods and materials:
- SBR and PBR are used to produce tires and plastic materials
- Styrene-butadiene (SB) latex is used to produce carpet and paper coatings
- Neoprene is used in gloves, wetsuits, waders and foams
- Nitrile rubber is used in hoses, gloves, gaskets and seals
Plastics made using butadiene-based rubbers are primarily acrylonitrile-butadiene-styrene (ABS) resins, high-impact polystyrene and styrene-butadiene latex, although other plastics use these rubbers as well. Butadiene is also used in the manufacture of adiponitrile, a precursor for nylon-6,6, which is used to produce carpets, textiles and plastic parts.
