Can the development of auto plastic parts usher in a new development peak?

Under the aggressive global financial crisis, the global plastics industry must continue to grow steadily, and improving the quality and technological content of plastic products has become the only way out. Recently, in the Beijing Exhibition Hall, the outstanding performance of the plastic products and high-tech content surprised exhibitors. The "carcass" of a pure white car in the exhibition hall attracted many visitors. This car "skeleton" is different from the car made of traditional steel materials, from the ceiling, dashboard frame, console, to the lampshade and engine. The cover, even the front and rear bumpers, all use a special plastic material.

In fact, the application of plastic parts in automobiles has been developed for a long time, and the application of automotive parts has significant advantages in reducing the weight of automobiles, saving fuel, promoting environmental protection, and recycling. Among them, polypropylene (PP) is the most representative of the engineering plastics that can replace steel. As the most common plastic used in our lives, it is difficult to use it directly as engineering plastics. It must be “modified”, that is, it must be replaced with steel after it has been engineered and high-performance. For the end user, the quality advantages of plastic products will become more and more significant, especially its lighter weight, which helps to save fuel, which is the main reason for the automotive industry's greater demand for plastic parts, and because of the plastic With thermal insulation, this is the key to building energy savings.

Recently, China’s auto market has become a hot topic in the global auto market. As the automobile industry of the ten major industry revitalization plans, driven by the favorable factors introduced in the automobile to the countryside and the automobile industry promotion plan, Sales volume has risen steadily, and even far exceeds sales in the same period last year that were not affected by the economic crisis. However, the weakness of the global auto market can not be ignored. The decline in auto demand led Japan's exports to the United States to decline for the 18th consecutive month, a decrease of 58% to 556.5 billion yen, and Japan’s exports to the EU also fell for the seventh consecutive month. The EU's exports fell 55% to 491.3 billion yen. Japan’s exports to China have dropped by 40% to 611.8 billion yen, as the demand for automobiles, plastics, semiconductors and other electronic components in the Chinese market has dropped significantly.

In January 2009, Craytech, the automotive plastic parts supplier, declared bankruptcy and became a victim of the wilting North American auto market. Less than two months later, in March 2009, Plastal, a leading supplier of automotive plastic parts in Europe, announced Bankruptcy, naturally due to the sharp decline in automotive industry demand, Plastal is one of the major suppliers of automotive plastic parts in Europe, with sales of 1.3 billion euros in 2008. When people sigh with regret, they can't help thinking about how to get plastic parts out of the winter.

On the one hand, the application of plastic parts in automobiles can effectively reduce the weight of the vehicle and achieve lighter weight of the vehicle, thus saving fuel, which is one of the important ways for the vehicle to achieve energy conservation and emission reduction. Plastic itself is recyclable, so the recycling of auto parts is a top priority for the sustainable development of the automotive plastics industry. It is of great significance to save energy, promote environmental protection and accelerate harmonious development. Automotive plastic parts, as components that can be recycled, are necessary factors for the sustainable development of the automotive industry. Nowadays, the research and development of the recyclable parts of automotive plastic parts has been highly valued by automobile manufacturers in various countries. Therefore, we want to survive and develop in the weak global automotive market. The research and development of plastic parts in terms of recyclability is necessary.

On the other hand, R&D and application of new automotive plastic products, such as Toyota Motor, are looking forward to bioplastics, indicating that by 2015, 20% (mass ratio) of plastic used in automobiles will be replaced with bioplastics. In order to achieve the above-mentioned replacement ratio, it is also necessary to achieve technological breakthroughs in the heat resistance, formability, impact resistance, and long-term reliability of bioplastics. Toyota has started to advance research on the above topics. At present, the proportion of various plastics used in automobiles is: polypropylene (PP) is less than 50%, and the total amount of main materials such as polyvinyl chloride (PVC), polyurethane (PU) and ABS resin accounts for about 80%. Toyota plans to gradually replace these plastics with bioplastics by 2015. The first thing that will be replaced with bioplastics is the "built-in parts" inside the car.

In Europe and the United States, 30%-40% of engineering plastics consumption is concentrated in the automotive sector; in the proportion of consumption in the engineering plastics market in China, the amount of automobiles has accounted for 11.82%, followed by electrical and electronic (the proportion of its consumption is 30.4. %). Therefore, industry analysts said that with the rapid demand for plastics in the automotive industry in recent years, China's plastics industry and the automotive industry has formed a trend of "a glory and a loss." As auto bodies, interior trims, bumpers and even engines are all using various types of plastics, the domestic plastics industry will also be accompanied by the stimulating policies of the auto industry.
