Cars are flooding our lives. Even in remote villages, we can see them. Almost become one of us. Modern industry has also been upgrading the car configuration to make it more suitable for us. It is more convenient and comfortable. It is the word that has been heard for more than a decade. It mainly reduces the weight of the car to reduce fuel consumption, reduces the cost of the entire vehicle, and achieves the effect of energy conservation and emission reduction. The modified nylon PA plastic plays a role that cannot be ignored in lightweighting. Has already accounted for 8% of the car, the proportion of the number will be further increased, to help fuel lighter.
A kilogram of plastic in a car can replace 3 kilograms or even heavier steel. When the weight is reduced by 10%, the fuel consumption can be reduced by about 8%. From the perspective of the application of modified nylon PA plastics in automobiles, with the modification technology Development, from the initial interior parts gradually developed to external parts, engines, bumpers and other peripheral components, the scope of application has been expanding, the application has been expanded to 14 as many.
At present, modified PP is the most widely used category for automotive modified plastics, accounting for about 46%, followed by modified nylon PA plastics, about 8%, modified ABS about 6%, modified PC/ABS about 5%, About 6% of PE, about 5% of modified PVC, about 2% of modified POM, and about 2% of modified PBT.
According to statistics, the amount of modified plastics used in domestic vehicles has reached 150KG/vehicle, and the demand for domestic automotive modified plastics is between 3.5 and 5 million tons. It is estimated that by 2022 China's automobile output will reach 40 million, with the With continuous improvement, the total demand for modified plastics will increase by about 6%, and the total demand will exceed 6 million tons.
In addition, the advent of new energy vehicles will further warm the modified nylon PA plastics industry. In addition to being lightweight, it also needs to consider how far a car can run with electric energy. At present, the development of domestic new energy vehicles has encountered a bottleneck (PS: New Energy Vehicles) Energy-saving and environmental protection, but also get subsidies, but often run into the road and worry about not find the charging pile and frightened, difficult to buy a variety of accessories, difficult to charge, repair the car difficult, while vigorously promoting the use of various factors to limit the use of Said that new energy vehicles really encountered a bottleneck. ) The lack of battery power has caused automakers to further reduce the body's own weight in order to meet the needs of users, and thus trying to get rid of the factors that restrict its development. I believe in the near future Domestic new energy vehicles will surely break through the bottleneck. The fantasy of 'manpower for a car' will eventually come true.
