"Energy saving, environmental protection and safety" are the eternal theme of automobile development. The plasticization of automobiles has brought about the lightweight of automobiles, and the lightweight of automobiles has brought about energy conservation. At present, in the automobile industry, the material of automobile exterior parts has changed from mainly metal alloy materials to a variety of modified plastic materials. This will not only reduce production costs, but also design more fashionable and more conformable materials. It also can greatly reduce the quality of the car. With the development trend of automotive materials replacing steel with plastics, green environmental protection and new energy industries, Qingdao Yishibao Plastics Co., Ltd. has been providing innovative solutions and technical support for the development of automotive plastic materials for many years.

The bumper is the first guarantee for car safety. When a car crashes, it plays a role in absorbing energy, reducing the collision, and protecting safety. It is an important part of the safety structure of modern cars and one of the auto parts with the largest amount of plastic. Plastic bumpers currently account for more than 90% of the world's automotive plastic consumption. Bumpers produced with modified PP as raw materials have the advantages of easy processing, low cost, light weight and recyclability.
