Styrene-butadiene or styrene-butadiene rubber (SBR) describe families of synthetic rubbers derived from styrene and butadiene (the version developed by Goodyear is called Neolite [1]). These materials have good abrasion resistance and good aging stability when protected by additives.
The most prevalent synthetic rubber is styrene-butadiene rubbers (SBR) derived from the copolymerization of styrene and 1,3-butadiene. Other synthetic rubbers include: polyisoprene, prepared by polymerization of isoprene; neoprene, prepared by polymerization of 2-chlorobutadiene; nitrile rubber made from cyanobutadiene or 2-propenenitrile and ...
Chloroprene rubber (CR), polychloroprene, neoprene; Butyl rubber (copolymer of isobutene and isoprene, IIR) Halogenated butyl rubbers (chloro butyl rubber: CIIR; bromo butyl rubber: BIIR) Styrene-butadiene rubber (copolymer of styrene and butadiene, SBR) Nitrile rubber (copolymer of butadiene and acrylonitrile, NBR), also called Buna N rubbers
Neoprene's burn point is around 260 °C (500 °F). [21] In its native state, neoprene is a very pliable rubber-like material with insulating properties similar to rubber or other solid plastics. Neoprene foam is used in many applications and is produced in either closed-cell or open-cell form.
The styrene-butadiene materials possess a two-phase microstructure due to incompatibility between the polystyrene and polybutadiene blocks, the former separating into spheres or rods depending on the exact composition. With low polystyrene content, the material is elastomeric with the properties of the polybutadiene predominating.
The polybutadiene is dissolved in styrene, which is then subjected to free-radical polymerization. The growing chains can add across the double bonds of rubber molecules forming polystyrene branches. The graft copolymer is formed in a mixture with ungrafted polystyrene chains and rubber molecules. [23]
The main polymers subjected to sulfur vulcanization are polyisoprene (natural rubber) and styrene-butadiene rubber (SBR), which are used for most street-vehicle tires. The cure package is adjusted specifically for the substrate and the application.
Nitrile butadiene is also used to produce moulded goods, footwear, adhesives, sealants, sponges, expanded foams, and floor mats. Its resilience makes NBR a useful material for disposable lab, cleaning, and examination gloves. Nitrile rubber is more resistant than natural rubber to oils and acids, and has superior strength, but has inferior ...
