Question:

What type of Plastic?

which type and grade plastic is used to make car bumpers?

Answer:

Some Chevy bumpers, especially front bumpers are constructed with integral crumple zones. Crumple zones are designed to absorb the force of impact; the crumple zones are designed to flex on impact. As the Chevy bumper flexes, the action of the bending bumper converts the kinetic energy of the car into heat. This way further damage to the car is prevented. Nowadays, car front bumpers are constructed out of rubber, plastic, urethane, fiberglass or painted light metal. These are also durable, though not as tough as the heavy steel used in the vintage cars, but technology has provided them with ways to divert danger away from the occupants of the vehicle. Chevrolet is continually finding ways to make them safer and more effective in shielding the owners from danger.
