This paper discusses the current applications of urethane in flexible body parts which for 1973 cars has resulted in designs for bumper covers, bumper to body fillers, and body extensions. The flexible parts are color-keyed extensions of the body surface also matching the car body in luster and texture. Most importantly, they meet government requirements for bumper impact capability There is a discussion of the tests established which included impact testing and compression recovery. The advantages and disadvantages of the cast-urethane process and injection-molded process are presented.
