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 ...

   Other toxic effects such as endocrine disruption ... (PVA), polytetrafluoroethylene (PTFE), butyl rubber, nitrile rubber, and Neoprene. [14] Structure and toxicity ...

4. List of gasoline additives - Wikipedia

   en.wikipedia.org/wiki/List_of_gasoline_additives

   Butyl rubber (as polyisobutylene succinimide, detergent to prevent fouling of diesel fuel injectors) Ferrous picrate, used in diesel fuel to increase fuel conversion efficiency and reduce emissions; Two-stroke oil, for lubrication of small engines reliant on crankcase compression; Upper cylinder lubricant, extensively advertised but of unproven ...

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. Tire-derived fuel - Wikipedia

   en.wikipedia.org/wiki/Tire-derived_fuel

   Tires are typically composed of about 1 to 1.5% Zinc oxide, [6] which is a well known component used in the manufacture of tires and is also toxic to aquatic and plant life. The chlorine content in tires is due primarily to the chlorinated butyl rubber liner that slows the leak rate of air.

7. 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.

8. Cationic polymerization - Wikipedia

   en.wikipedia.org/wiki/Cationic_polymerization

   Butyl rubber gloves. Butyl rubber, in contrast to PIB, is a copolymer in which the monomers isobutylene (~98%) and isoprene (2%) are polymerized in a process similar to high molecular weight PIBs. Butyl rubber polymerization is carried out as a continuous process with AlCl 3 as the initiator. Its low gas permeability and good resistance to ...

9. 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 ...
