2. Butyl rubber - Wikipedia

   en.wikipedia.org/wiki/Butyl_rubber

   Butyl rubber gloves. Butyl rubber, sometimes just called "butyl", is a synthetic rubber, a copolymer of isobutylene with isoprene. The abbreviation IIR stands for isobutylene isoprene rubber. Polyisobutylene, also known as "PIB" or polyisobutene, (C 4 H 8) n, is the homopolymer of isobutylene, or 2-methyl-1-propene, on which butyl rubber is ...

4. Isobutylene - Wikipedia

   en.wikipedia.org/wiki/Isobutylene

   Polymerization of isobutylene produces butyl rubber (polyisobutylene or PIB). Antioxidants such as butylated hydroxytoluene (BHT) and butylated hydroxyanisole (BHA) are produced by Friedel-Crafts alkylation of phenols with isobutylene. tert-Butylamine is produced commercially by amination of isobutylene using zeolite catalysts: [6]

5. Synthetic rubber - Wikipedia

   en.wikipedia.org/wiki/Synthetic_rubber

   Examples include Viton rubber, EPDM and butyl rubber. A new class of synthetic rubber is the thermoplastic elastomers which can be moulded easily unlike conventional natural rubber vulcanized rubber. Their structure is stabilized by cross-linking by crystallites in the case of polyurethanes or by amorphous domains in the case of SBS block ...

6. Nitrile rubber - Wikipedia

   en.wikipedia.org/wiki/Nitrile_rubber

   Nitrile rubber, also known as nitrile butadiene rubber, NBR, Buna-N, and acrylonitrile butadiene rubber, is a synthetic rubber derived from acrylonitrile (ACN) and butadiene. [1] Trade names include Perbunan, Nipol, Krynac and Europrene. This rubber is unusual in being resistant to oil, fuel, and other chemicals.

7. Rubber pollution - Wikipedia

   en.wikipedia.org/wiki/Rubber_pollution

   Rubber pollution, similar to plastic pollution, occurs in various environments, and originates from a variety of sources, ranging from the food industry processing chain to tire wear. [ 1 ] [ 2 ] Synthetic and natural rubber dust and fragments now occur in food, airborne as particulates in air pollution, hidden in the earth as soil pollution ...

9. Styrene-butadiene - Wikipedia

   en.wikipedia.org/wiki/Styrene-butadiene

   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.
