At present, the main direction of the development of automotive materials technology in the world is light weight and environmental protection. The relative density of automobile plastics is low, and the exterior parts are made of plastic-made steel, which can reduce the weight of the automobile and achieve energy-saving purposes. Reducing the quality of the car itself is one of the most effective measures to reduce vehicle displacement and improve combustion efficiency. According to estimates, for every 10% reduction in the quality of the car itself, fuel consumption can be reduced by 6% to 8%.
Lightweight embodiment of automotive plastics
The use of elastomers and foamed plastics that absorb shock energy and vibration energy to make instrument panels, seats, headrests and other products can reduce the damage to the human body during collisions and improve the safety factor of the vehicle. Structural parts are often made of high-strength engineering plastics to reduce quality, reduce costs, and simplify processes such as plastics for fuel tanks, engines, and parts on the chassis.
Personalized development of automotive plastics
The use of automotive plastics also helps the car to develop in a personalized direction. Plastic products have a high degree of freedom in design and can be made into transparent, translucent or opaque products with a variety of appearances. In addition, the plastic processing performance is good, and the complex products can be molded in one time and mass-produced, with high efficiency, low cost and remarkable economic benefits. If calculated in unit volume, the cost of producing plastic parts is only 1/10 of that of non-ferrous metals.
