Just about any automobile collision will result in damage to the bumper. Before the 1980's, most of the bumpers were made from steel. Today, just about all automobiles have bumper covers made from plastic. Most of the early plastic bumper covers were made from urethane and, in 1981, Polyvance (formerly Urethane Supply Company) was formed to address the needs of bumper recyclers and to supply products to repair urethane bumper covers. Hence the name Urethane Supply Company. As auto manufacturers began using other materials in bumper covers, Urethane Supply Company (now Polyvance) developed products to repair those types of plastics as well.
