How thick is the top of the rear bumper?

[SanDaniel]

The top of the rear bumper is generally less than two millimeters thick. Function of the rear bumper: The rear bumper is a crossbeam located below the taillights. In addition to maintaining its original protective function, the front and rear bumpers of a car also aim to achieve harmony and unity with the vehicle's body shape, as well as pursue lightweight construction. Nowadays, most car bumpers are made of polypropylene plastic. Manufacturing process: Generally, bumpers are made of modified PP material due to its advantages of balanced plasticity and rigidity, lightweight and thin properties, and low cost. Some bumpers made of other materials (such as fiberglass, carbon fiber, etc.) may be phased out due to poor environmental performance (non-recyclable) or high costs. Therefore, in the coming years, modified PP materials and increasingly mature thermoplastic elastomers (TPO) will dominate the production of car bumpers.
