In the future, polyolefin products in the automotive industry will replace a large number of expensive non-ferrous metals and alloys. This will not only improve the aesthetics and design flexibility of automobiles, but also reduce the cost of parts processing, assembly and maintenance, and can also reduce the cost. The energy consumption of the car.
According to the latest statistics from the National Bureau of Statistics, in January 2004, a total of 39,512 automobiles were sold in Beijing, an increase of 81.7% over the same period of last year. With the rapid development of the automobile industry, the demand for polyolefin products for automobiles will also be strong.
At present, the global market size of automotive plastic products is 4.54 million tons/year, and the volume of plastic products for bicycles is also rapidly expanding, and automotive interior parts are basically plasticized. The application range of plastics is expanding from the interior parts to the exterior parts, body parts and structural parts. The future development will focus on the development of structural parts, reinforced plastic composites for exterior parts, high-performance resin materials and plastics, and the recyclability of materials. Sex is highly concerned. According to analysis by industry experts, it is expected that by 2005 China's auto consumption will reach a total of 150,000 tons of various polyolefin products, and by 2010, the demand will reach 230,000 tons, and will maintain an average annual growth rate of 10%.
In the future, polyolefin products will be widely used in the automotive industry. Because of the low density, good performance, and low cost of polyolefin materials, there has recently been a trend toward the integration of automotive interior and exterior materials into polyolefin materials. Therefore, the use of polyolefin products will be relatively low. Big growth.
For each additional value of 1 yuan in the automobile industry, it will bring an increase of 2.63 yuan to the upstream of the relevant industrial clusters. The contribution rate of this industrial cluster to the growth of the Chinese economy is about 12%. As a research and development department and manufacturer of polyolefin raw materials, we should seize this business opportunity of polyolefin products for automobiles to increase the varieties and grades of polyolefin raw materials, develop varieties that can be used as functional parts and structural parts of automobiles, and accelerate convergence with international standards.
In the application of automotive polyolefin products, China has developed a number of effective new technologies, gas-assisted injection molding technology, three-dimensional and multi-layer hollow molding technology, surface treatment technology will be well applied.
