What material is good for car bumpers?

[LaLincoln]

Polypropylene plastic is good for car bumpers. Polypropylene plastic is made from toughened polypropylene material as the raw material, which is then injection-molded into plastic. This material has high rigidity, impact resistance, scratch resistance, and paintability. After the injection-molded bumper is installed on the vehicle, it can withstand an impact of 8 km/h without breaking and has the elasticity to recover. Its performance is similar to PU, but the cost is reduced by 10% to 20%. Below are some parking precautions: 1. No parking in areas with no-parking signs: No-parking signs indicate that within the specified range, all vehicles are prohibited from parking temporarily or for a long time. 2. No parking within yellow grid lines: Yellow grid lines indicate that parking is prohibited in this area for any reason. They are commonly found at intersections, entrances, and exits. 3. Yellow solid lines: On roads with yellow solid lines, parking is prohibited. The length of the yellow solid line indicates the size of the no-parking area. 4. No parking near bus stops: Parking is prohibited in areas such as bus stops, gas stations, emergency stations, fire hydrants, etc.
