General requirements to absorb the impact energy under 8 km/h speed, some laws and regulations up to 4 km/h, the protection of the impact and function of the body and the body after a permanent deformation and bumper, there is rules.
2。 Collision protection for pedestrians.

5。 Its air power performance requirements.
plastic bumper has better strength, rigidity and adornment sex, from a performance point of view, when the car collision accident can have buffer effect, protect the body before and after: look from the appearance, high quality of the spray can make its naturally combined with body, has the very good adornment sex, becomes an important part of a car exterior decoration.
