Polymer automotive materials have many advantages that traditional materials did not have in the past. Mainly manifested in various aspects such as light weight, good appearance decoration effect, multiple practical application functions, good physical and chemical properties, easy processing and forming, energy saving, and sustainable utilization. The main features of polymer automotive materials are as follows.
1. Light weight
One of the most prominent advantages of polymer automotive materials is that they have the characteristics of light weight and high strength. Since the average specific gravity of various plastics is only 15-20% of ordinary steel, it is also lighter than ordinary wood. This feature has outstanding advantages especially for high-end large cars, which can reduce a large amount of self-weight.
2. Good processing performance
Polymer automotive materials have very good processing properties. Due to the plasticity of polymer automotive materials and the good compatibility with other materials, different material components can be used, with the help of various modern molding and processing machinery, through extrusion, injection molding, calendering, molding, and blow molding. Processed into polymer automotive materials with different shapes, different properties, different colors, and different functions by other methods, such as direct extrusion into tubes, profiles, plates, injection into products with various shapes, and calendering into films, etc. , Can also be made into various colors, sandwiches, hollows, inserts and other products according to needs, and can also be subjected to secondary processing according to requirements, such as turning, punching, cutting, welding, and heating of mechanical products. Melting, cold sawing, compounding, etc.
3. Excellent comprehensive physical and chemical properties
Another advantage of polymer automotive materials is that they have multiple functions and can be used in special occasions. In addition to plasticity, most polymer materials have many excellent physical and chemical properties. Plastics have good insulation properties, excellent corrosion resistance, aging resistance, good wear resistance and scrubbing resistance, good waterproof and mechanical properties, and good bonding and bonding properties. They are processed into various A variety of automotive interior and exterior trim parts that require multiple performances and functions.
4. Excellent decorative effect
The most prominent advantage of polymer automotive materials is the excellent decorative effect. It can be processed into products with complex shapes and multiple colors at one time, and sometimes it needs to be printed, pasted, embossed, laminated, and colored to be processed into a very realistic image, pattern and pattern, which can imitate natural wood, metal, The texture of animal skin can also be hot-stamped, filmed, silver-plated, inlaid, etc. on the surface.
5. Energy saving and environmental protection
Another advantage of polymer automotive materials is that they can save energy and promote environmental protection. Because it can replace a large number of natural materials, it can save a lot of resources accordingly, play a role in protecting forest and stone resources, without destroying more ecological environment, and has the social value of energy saving and environmental protection. At the same time, due to the convenience of plastic processing and molding, the energy required to manufacture polymer cars is far less than processing natural materials with the same function, such as steel and animal skins, which can save a lot of manpower and energy. Most of the plastics used in automotive materials are thermoplastics, and the waste materials can be easily recycled and directly remanufactured. This makes polymer automotive materials on the road of sustainable processing and cleaner production, which has extremely positive environmental protection significance.
