Sheet of synthetic rubber coming off the rolling mill at the plant of Goodrich (1941) World War II poster about synthetic rubber tires. Production of synthetic rubber in the United States expanded greatly during World War II since the Axis powers controlled nearly all the world's limited supplies of natural rubber by mid-1942, following the Japanese conquest of most of Asia, particularly in ...
Kraton is the trade name given to a number of high-performance elastomers manufactured by Kraton Polymers, and used as synthetic replacements for rubber.Kraton polymers offer many of the properties of natural rubber, such as flexibility, high traction, and sealing abilities, but with increased resistance to heat, weathering, and chemicals.
The plastic kits and covers are mostly made of synthetic polymers like polythene, and tires are manufactured from polybutadienes. [1] However, due to the environmental issues created by these synthetic polymers which are mostly non-biodegradable and often synthesized from petroleum, alternatives like bioplastics are also being considered. They ...

Meanwhile, the government funded research into synthetic rubber compounds to attempt to solve this shortage. [ 11 ] Credit for the invention of Silly Putty is disputed [ 12 ] and has been attributed variously to Earl Warrick [ 3 ] of the then newly formed Dow Corning ; Harvey Chin; and James Wright , a Scottish -born inventor working for ...
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 ...
In Akron, scientists who had worked on the WWII synthetic rubber project saw the value of this work and helped form the Institute of Rubber Research, which opened at the University of Akron in 1956.
The term, a portmanteau of elastic polymer, [2] is often used interchangeably with rubber, although the latter is preferred when referring to vulcanisates. [3] Each of the monomers which link to form the polymer is usually a compound of several elements among carbon , hydrogen , oxygen and silicon .
