The main function of a bumper is to protect the car's body in a slight collision, typically at parking speed. The bumper structure on modern automobiles generally consists of a plastic cover over a reinforcement bar made of steel, aluminum, fiberglass composite, or plastic. In most jurisdictions, bumpers are legally required on all vehicles.
(Our Civic bumper is made of polypropylene.) Stamps of PUR (polyurethane plastic rigid) and TPUR (thermoplastic polyurethane elastomer) are plastics that powder when ground or sanded. The type of filler you use to repair the bumper depends on the plastic type, and there are many different manufacturers.
