Plastic products widely used in new energy vehicles
New energy vehicles are the development trend of the automotive industry. Statistics from relevant institutions show that the current number of new energy vehicles in the Chinese market exceeds 5 million. The prospects for new energy vehicles will be very broad. With their performance advantages, plastic materials have played an important role in promoting the lightweight of new energy vehicles. And the production of special parts. Data shows that the automotive industry has become one of the fastest-growing areas of plastic demand.
Lightweight is an important factor that has always restricted the development of new energy vehicles. Affected by the power system and market orientation, the lightweight development of new energy vehicles has always attracted attention. However, with the application of high-functional plastic materials in automobiles, the lightweight problem of new energy vehicles has been alleviated to a certain extent.
It is understood that new energy vehicles have a vast large demand for resins such as nylon, polypropylene, polyurethane. And other engineering plastics, accounting for more than 30% of the total resin market demand. The demand for polyvinyl butyral accounts for approximately More than 85% of the total demand. Plastic materials can be seen on the bumpers, fuel tanks, body panels and chassis, engine intake manifolds, clutch actuator systems, and many other important parts of automobiles.
Plastic products will help reduce car weight
Compared with traditional alloy materials, plastic parts have unparalleled advantages. Plastic products will help reduce the weight of cars. Data shows that for every 10% reduction in vehicle weight, fuel economy can increase by 5%. So new energy vehicles using plastic products can run farther.
Plastic products can also reduce the production cost of car companies. A simple injection-molded plastic part can perform the function of welding many metal parts together. The plastic can be molded into a more complex shape than the steel assembly. Which can reduce the integration process The number of parts used.
In addition, the elastic deformation characteristics of plastic products absorb a large amount of collision energy. Have a greater buffering effect on strong impacts, and play a good role in protecting vehicles and passengers. Plastics have strong corrosion resistance and will not be corroded if they are damaged locally. However, once the paint surface is damaged or the anti-corrosion is not well done in advance. It is easy to rust and corrodes. This not only affects the appearance of the car body. But also poses a safety hazard.
According to the composition of the plastic. Plastics with the required properties can be prepared by adding different fillers. Plasticizers, and hardeners, and mechanical strength and processing. And forming properties of the plastic can be modified to meet the requirements of different parts of the car. It can be said that plastic has contributed to the rapid development of new energy vehicles. And the rapid development of new energy vehicles has opened up a broad market for plastics.
