Plastic bumper covers are typically made of:

• A. ABS
• B. Polypropylene
• C. Polycarbonate
• D. Polyolefin or Urethane

Answer: (D)

Bumper covers are designed to be light, flexible enough to deform on impact, and easy to paint, while also being cost-effective. The plastics that fit these needs best are polyolefins—most commonly polypropylene—and polyurethane. These materials mold well into complex exterior shapes, absorb minor impacts without cracking, resist dents, and hold paint well, which is essential for an exterior automotive part. Other options like ABS are tougher and more rigid, not as forgiving for a cover that must absorb small impacts; polycarbonate is strong and clear but not the typical choice for bumper skins; polyolefin or urethane combinations cover the usual material choices used in bumper covers across manufacturers.
