Automotive Exteriors: Increasing Trends in Plastics Applications

Cars are indispensable in modern life, which provides great convenience for people's trav.

Key points of automotive exterior design

If the car interior is to provide people with a comfortable driving experience, then the car exterior is to make the vehicle more beautiful and to ensure the safety of the ri.

Depending on the country where the model is launched, the design process must fully implement local regulatory standar.

In addition, in several parts of the car exterior, the requirements for materials are also differe.

Types of Plastics and Automotive Exteriors

At present, the plastics used in automobiles are generally PP (polypropylene), PE (polyethylene), ABS (polyurethane), PMMA (polyetheretherketone), PA (nylon), PC (polycarbonate),e.

Although in some special parts, the strength of bio-based plastics is still a factor that restricts its large-scale use, but there have been successful cases in the field of automotive exterio.

Application of plastics in automotive exteriors

Plastic processing performance and use performance are relatively ideal, and compared with metal materials used in traditional automobile manufacturing, lower cost and lighter weight also conform to the trend of lightweight automobiles, so more and more plastic automobile parts are replac.

We give examples of the application of several common plastics in automotive exteriors:

Bumper: including front bumper and rear bump.

Rearview mirror: Due to the long-term influence of weather such as sun and rain, and factors such as driving bumps, the material of rearview mirror needs to have certain weather resistan.

Luggage rack: To ensure that the luggage rack is not damaged under various complex stress conditions, the material is required to have sufficient fatigue strength to ensure that the luggage rack will not suffer serious fatigue damage when the car is running fast and emergency braki.

Car lights: It can be divided into headlights, rear lights, turn signals, license plate lights, e.

In addition, it is worth noting that as the advantages of plastic become more and more obvious, there is a trend of expanding the use of plastic materials in the covers and chassis accessories such as engine covers, tailgates and fuel tan.

        For example, after 2000, the market share of plastic fuel tanks in the United States, the European Union and Japan has exceeded 90%, while the domestic market share is much lower due to insufficient knowledge popularization and other reaso.

        Conclusion: As the trend of automobile lightweighting becomes clearer, the use of plastics in automobile decoration becomes more and more extensi.
