Nitrile rubber (NBR),  also called Nitrile-butadiene rubber,  an oil-resistant synthetic rubber produced from a copolymer of acrylonitrile and butadiene. Its main applications are in fuel hoses, gaskets, rollers, and other products in which oil resistance is required.

Nitrile rubber is mostly used where high oil resistance is required, as in automotive seals, gaskets, or other items subject to contact with hot oils. The rolls for spreading ink in printing and hoses for oil products are other obvious uses. NBR is also employed in textiles, where its application to woven and nonwoven fabrics improves the finish and waterproofing properties.

NBR manufacturers and trade names include: Nipol ™ NBR from Zeon Corporation; Buna N, Perbunan™, Krynac™, Baymod N™ from Lanxess; Nacar NBR from Nantex Industry; Butadiene-nitrile SKN from Omsk Kauchuk; Arnipol from Petrbras Energia SA; Europrene® N from Polimeri Europa; Paracril and Paraclean from INSA/Grupo Kuo and Ker N™ and Ker NVC™ from Synthos.

Other nitrile rubber manufacturers include JSR Corporation, Kumho Petrochemical, Eliokem, LG Chemical, Lion Copolymer, PetroChina and Sibur Holdings.

Styrene-butadiene rubber (SBR) is one of the most versatile copolymer rubber compounds. It consists of the organic compound styrene and the chemical budatiene, with the amount of budatiene usually being about three times more than the amount of styrene. SBR is a stable synthetic that is resistant to abrasion. It is used in a wide variety of products, such as automobile tires, children's toys, shoe soles and even chewing gum.

SBR can be found in many products, some of them predictable and others that might be surprising. Along with being used in the production of new auto tires, many companies that retread old tires use a coating of this rubber to produce the retreads. Among the other obvious uses are in gaskets, belts and hoses for machinery, and brake pads and clutch pads for vehicles. Around the home, SBR is found in toys, caulking compounds, sponges, shoe soles and floor tiles. Some of the less expected uses of it are is the production of sanitary products, surgical gloves, and gum. This rubber also can be used to coat the walls, ceiling, and floors of rooms that are prone to being damp, such as basement rooms.

Polybutadiene is a synthetic rubber that is a polymer formed from the polymerization process of the monomer 1, 3-butadiene. Polybutadiene has a high resistance to wear and is used especially in the manufacture of tires, which consumes about 70% of the production. Another 25% is used as an additive to improve the mechanical strength of plastics such as polystyrene and acrylonitrile butadiene styrene (ABS). Polybutadiene rubber accounted for approx. a quarter of total global consumption of synthetic rubbers in 2012. It is also used to manufacture golf balls, various elastic objects and to coat or encapsulate electronic assemblies, offering high electrical resistivity
