Analysis on the development status of plastic alloy

At present, the largest users of plastic alloy products in the world are automotive parts, followed by mechanical and electronic components. Steel, copper, aluminum and aluminum are commonly used in heating radiators on the market. These metal materials have defects such as easy oxidation and corrosion, and the product has a short service life. In order to solve this problem and expand the application field of engineering plastics, Dongfang Thermal Transmission Technology Co., Ltd., with the technical strength of Yuyao China Plastics City Plastics Research Institute, has cooperated with Tsinghua University, Zhejiang University and other institutions of higher learning to develop thermal plastics and plastics. Radiator research. After several years of research, high-quality polymer thermal conductive modified materials based on PPR and copolymerized with various mineral bases have been developed. Subsequently, the company independently developed radiator automatic hot-melt welding machine, automatic spraying line, 5000-week life tester, thermal power tester, etc., providing hardware facilities for research and development and production of anti-corrosion radiators.

Faster development

China's research on plastic alloys began in the 1960s and has developed rapidly in recent years. According to statistics, the current consumption of plastic alloys (including modified resins) in China is about 1.2 million to 1.4 million tons, while the domestic supply is less than 600,000 tons, and the annual import volume is as high as 900,000 tons; and China's plastic alloys (mainly Blended resin and modified resin) are mainly used in home appliances, electronics, automotive and other industries. Compared with developed countries, China's plastic alloy application market still has a lot of room for expansion.

Demand potential

With the sustained and rapid development of China's economy, the demand potential of China's plastic alloy market will be huge in the next few years, especially the rapid growth of electronic communication, automobile and construction industry, which will drive the rapid development of China's engineering plastics alloy industry. It is estimated that by 2008, the total demand for five major engineering plastics in China will reach 1 million tons, and the demand for five major synthetic resins will reach 52 million tons, making it one of the largest importers of plastic alloys in the world.

Not yet formed

At present, China's plastic alloy research and production are still in a state of sporadic dispersion, and have not yet formed a scale. The overall level of the industry is low, which is far from the advanced level of foreign countries. In the domestic plastic alloy production variety structure, the production of high value-added special engineering plastic alloys is almost in the blank, basically the production of general plastic alloys and modified products. In 2004, there were more than 300 plastic alloy production enterprises in China. It is estimated that the production capacity of plastic alloys (including modified pellets) is 700,000-800,000 tons/year, and the output is about 600,000 tons/year. However, the larger enterprises account for only 15%, and the 15% of the enterprises account for more than 70% of the total output of plastic alloys in the country. Most of the enterprises are processing enterprises that produce plastic alloys through plastic compounding and extrusion processes. Due to the large demand for plastic alloys in China, and mainly relying on imports, it is very important to develop plastic alloy production, improve the competitiveness of domestic resins and the level of domestic plastic processing, especially for engineering plastics with higher profit and faster market growth. Alloy varieties are the top priority of China's plastic alloy industry!
