TireA tire (North American English) or tyre (Commonwealth English except Canada) is a ring-shaped component that surrounds a wheel's rim to transfer a vehicle's load from the axle through the wheel to the ground and to provide traction on the surface over which the wheel travels. Most tires, such as those for automobiles and bicycles, are pneumatically inflated structures, which also provide a flexible cushion that absorbs shock as the tire rolls over rough features on the surface.
FKMFKM is a family of fluorocarbon-based fluoroelastomer materials defined by ASTM International standard D1418, and ISO standard 1629. It is commonly called fluorine rubber or fluoro-rubber. FKM is an abbreviation of Fluorine Kautschuk Material. All FKMs contain vinylidene fluoride as a monomer. Originally developed by DuPont (under the brand name Viton, now owned by Chemours), FKMs are today also produced by many companies, including: Daikin (Dai-El), 3M (Dyneon), Solvay S.A.
Monowitz concentration campMonowitz (also known as Monowitz-Buna, Buna and Auschwitz III) was a Nazi concentration camp and labor camp (Arbeitslager) run by Nazi Germany in occupied Poland from 1942–1945, during World War II and the Holocaust. For most of its existence, Monowitz was a subcamp of the Auschwitz concentration camp; from November 1943 it and other Nazi subcamps in the area were jointly known as "Auschwitz III-subcamps" (KL Auschwitz III-Aussenlager).
IsopreneIsoprene, or 2-methyl-1,3-butadiene, is a common volatile organic compound with the formula CH2=C(CH3)−CH=CH2. In its pure form it is a colorless volatile liquid. It is produced by many plants and animals (including humans) and its polymers are the main component of natural rubber. C. G. Williams named the compound in 1860 after obtaining it from the pyrolysis of natural rubber; he correctly deduced the empirical formula C5H8. Isoprene is produced and emitted by many species of trees (major producers are oaks, poplars, eucalyptus, and some legumes).
PolyurethanePolyurethane (ˌpɒliˈjʊərəˌθeɪn,_-jʊəˈrɛθeɪn; often abbreviated PUR and PU) refers to a class of polymers composed of organic units joined by carbamate (urethane) links. In contrast to other common polymers such as polyethylene and polystyrene, polyurethane is produced from a wide range of starting materials. This chemical variety produces polyurethanes with different chemical structures leading to many different applications. These include rigid and flexible foams, and coatings, adhesives, electrical potting compounds, and fibers such as spandex and polyurethane laminate (PUL).
BayerBayer AG (ˈbaɪ.ər, commonly pronounced ˈbeɪər; ˈbaɪɐ) is a German multinational pharmaceutical and biotechnology company and is one of the largest pharmaceutical companies in the world. Headquartered in Leverkusen, Bayer's areas of business include pharmaceuticals, consumer healthcare products, agricultural chemicals, seeds and biotechnology products. The company is a component of the EURO STOXX 50 stock market index. Bayer was founded in 1863 in Barmen as a partnership between dye salesman Friedrich Bayer (1825–1880) and dyer Friedrich Weskott (1821–1876).
ShoeA shoe is an item of footwear intended to protect and comfort the human foot. Though the human foot can adapt to varied terrains and climate conditions, it is vulnerable, and shoes provide protection. Form was originally tied to function but over time shoes also became fashion items. Some shoes are worn as safety equipment, such as steel-toe boots, which are required footwear at industrial worksites. Additionally, fashion has often evolved into many different designs, such as high heels, which are most commonly worn by women during fancy occasions.
ButeneButene, also known as butylene, is an alkene with the formula . The word butene may refer to any of the individual compounds. They are colourless gases that are present in crude oil as a minor constituent in quantities that are too small for viable extraction. Butene is therefore obtained by catalytic cracking of long-chain hydrocarbons left during refining of crude oil. Cracking produces a mixture of products, and the butene is extracted from this by fractional distillation.
MonomerIn chemistry, a monomer (ˈmɒnəmər ; mono-, "one" + -mer, "part") is a molecule that can react together with other monomer molecules to form a larger polymer chain or three-dimensional network in a process called polymerization. Monomers can be classified in many ways. They can be subdivided into two classes, depending on the kind of the polymer that they form. Monomers that participate in condensation polymerization have a different stoichiometry than monomers that participate in addition polymerization: Other classifications include: natural vs synthetic monomers, e.
Rubber gloveA rubber glove is a glove made out of natural rubber or Synthetic rubber. The term ‘rubber’ refers to durable, waterproof and elastic material made from natural or synthetic latex. Rubber gloves can be unsupported (rubber only) or supported (rubber coating of textile glove). Its primary purpose is protection of the hands while performing tasks involving chemicals. Rubber gloves can be worn during dishwashing to protect the hands from detergent and allow the use of hotter water.
