The document discusses elastomers, a category of pliable plastic materials that are good at insulating, withstanding deformation, and stretching many times their length. It defines elastomers as materials with molecules that are tangled in a jumbled mess but become orderly when stretched. The document then describes several common types of elastomers, including natural rubber (polyisoprene), synthetic rubber (polychloroprene and polybutadiene), polystyrene, polyisobutylene. It lists uses of elastomers such as in automobile wheels, balls, bicycle seats, shoe soles and tire inner liners.
