The rapid development of new energy vehicles, the vast space of plastic materials-the price of anti-fog mirrors

In August this year, my country's new energy vehicle sales reached 101,000, a year-on-year increase of 49.5%, higher than the 47.7% growth rate in July. In contrast, the entire auto market sold 2.103 million vehicles in August, a year-on-year decrease of 3.8%. As a leader in the plug-in market, BYD’s sales of new energy vehicles reached 22,000 in August, an increase of 85% year-on-year. Among them, the sales of plug-in hybrid vehicles reached 11,000. BYD expects that as the capacity bottleneck eases, sales of new energy vehicles will continue to rise in the second half of the year, which is expected to contribute considerable sales and revenue to the company. New energy vehicles are the development trend of the automotive industry. Statistics from relevant agencies show that the current number of new energy vehicles in the Chinese market exceeds 1 million, and it is expected to exceed 5 million in 2020. The prospects for new energy vehicles will be very broad. By virtue of its 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. According to market information agency Markets and Markets, the global market value of automotive plastics is expected to increase from USD 21.616 billion in 2012 to USD 46.112 billion in 2018, and consumption is expected to increase from 7.1 million tons in 2012 to 11.3 million tons in 2018. ——The compound annual growth rate of demand during 2018 will reach 13.4%. This is mainly attributable to the steady growth of global automobile production and the lighter weight of automobiles that have led to an increase in the amount of modified plastics used in bicycles. 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 very 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. Compared with traditional alloy materials, experts say that 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 be increased 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 a steel assembly, which can reduce the integration process. 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 have a good protective effect on vehicles and passengers; plastics have strong corrosion resistance, local damage will not corrode, and steel Once the paint is damaged or the anti-corrosion is not done well, it is easy to rust and corrode, which not only affects the appearance of the car body, but also poses a safety hazard; according to the composition of the plastic, different fillers, plasticizers and The hardener produces plastics with required properties, and modifies the mechanical strength and processing and molding properties of the plastics to meet the requirements of different parts on the car. It can be said that plastics have contributed to the rapid development of new energy vehicles, and at the same time, the rapid development of new energy vehicles has opened up a broad market for plastics.
