At present, the early stage in the reform of the automotive industry is mainly electrification. During this period, the car’s core components are no longer the engine, gearbox and chassis,they are the three electric systems like battery, motor and electronic control,which accounts for more than 50% in the cost of new energy vehicles. But the cost of power batteries accounts for 90% among the cost of three electrics. Therefore, the power battery system can be called the "heart" of new energy vehicles. #tpu car clothing extrusion machine
The lightweight of new energy vehicles is mainly related to electronics, such as connectors, charging interfaces, power battery peripheral materials, etc. Replacing metal with plastic, can reduce weight by about 30% meanwhile the performance meets the requirements. At present, a pure electric vehicle uses lightweight plastics, which can reduce the weight by about 100KG.
Combined with the use conditions of automotive products,the engineering plastics need to meet the following performance requirements:
1Chemical corrosion resistance, oil resistance, high and low temperature resistance;
2.Excellent mechanical properties, high fluidity and excellent processing performance;
3.Excellent surface properties and good dimensional stability;
4.It has good waterproof, moisture-proof, flame-retardant, environmental protection and thermal conductivity functions;
5.Good dielectric resistance, suitable for electrical places;
6.Good weather resistance, good long-term performance, and can be used for a long time in harsh environments.
