Goodyear Tire and Rubber Company Goodyear Tire and Rubber Company The Goodyear Tire & Rubber Company is an American multinational tire manufacturing company founded in 1898 by Frank Seiberling and based in Akron, Ohio. Goodyear manufactures tires for automobiles, commercial trucks, light trucks, motorcycles, SUVs, race cars, airplanes, farm equipment and heavy earth-mover machinery. It also produced bicycle tires from its founding until 1976. As of 2017, Goodyear is one of the top four tire manufacturers along with Bridgestone (Japan), Michelin (France) and Continental (Germany). The company was named after American Charles Goodyear, inventor of vulcanized rubber. The first Goodyear tires became popular because they
Rubber toughening of waste rubber from car tires has sparked interest in finding uses for this discarded rubber. The rubber can be turned into a fine powder, which can then be used as a toughening agent for polystyrene. However, poor miscibility between the waste rubber and polystyrene will weaken the material. This problem requires the use of a compatibilizer (see "compatibilization") in order to reduce interfacial tension and ultimately make rubber toughening of polystyrene effective. A polystyrene/styrene-butadiene copolymer acts to increase the adhesion between the dispersed and continuous phases. Rubber toughening Rubber toughening is a process in which rubber nanoparticles are interspersed
