From January to October 2010, the cumulative export volume of plastic products in China was approximately 6.11 million tons, an increase of 13.8% from the same period of 2009. Among them, the export volume of plastic products in October was about 585,000 tons, amounting to US$1.52 billion.
China is one of the largest producers of plastic products. There are numerous processing companies, but there are a small number of companies with a certain scale. Most of them are small and medium-sized enterprises. The level of technology is relatively backward, and the added value of products produced is not high. And China's exports are mostly daily necessities and handicrafts, and there are relatively few special engineering plastic products with high added value. This shows that to develop China's plastics industry, the key is to develop engineering plastics.
Engineering plastics are industrial plastics that are used as industrial parts or housing materials. They are plastics that are excellent in strength, impact resistance, heat resistance, hardness, and aging resistance. The Japanese industry defines it as "high-performance plastics that can be used as structural and mechanical parts, and have a heat resistance of 100°C or higher and are mainly used in industry."
Development status of China's engineering plastics industry After 10 years of development, China's engineering plastics industry has achieved fruitful results, and has gradually formed a complete industrial chain with the ability to combine resin synthesis, plastics modification and alloys, and processing and application. This was expressed by Yang Weicai, chairman of the China Engineering Plastics Industry Association, at the China Engineering Plastics Industry Association Summit held in Beijing on May 27.
Ten years ago, China's engineering plastics industry had just started, and production capacity was lagging behind demand. More than 85% of raw material resins were imported, and more than half of the modified resin materials used foreign products. Nowadays, China's engineering plastic resins can be produced in China. The polymerization capacity has reached about 600,000 tons per year, and the annual output of modified resin materials is also more than 2 million tons. Even the special engineering plastics that were embargoed by foreign countries in the past. Resins are now almost produced in China and can be exported in small quantities.
According to data from the China Engineering Plastics Industry Association, in the past 10 years, the average annual output value of China's engineering plastics has increased by more than 20%, the scale of the company has continued to grow, and the level of science and technology has increased. At present, there are large-scale companies in the engineering plastics synthesis, such as China Blue Group, Yuntianhua Group, Shenma Group, Yizheng Chemical Fiber, and Deyang Technology. As engineering plastics have particularly excellent performance, their level of technological development has been taken seriously by the government, and has been listed as a key option for high-tech in the national long-term science and technology development program. In this year's Ministry of Science and Technology's industry support plan, there are seven engineering plastics projects such as non-method polycarbonate, which are listed. In addition, after a long-term technical breakthrough, China's engineering plastics technology has developed rapidly. In terms of modified materials and resin alloys, some product technologies and quality indicators have also approached foreign advanced levels. Some of the special engineering plastic products process technology has entered the international advanced ranks.
Although China's engineering plastics have made considerable progress in the synthesis and processing, overall, there are still some shortcomings that the production capacity is excessively concentrated on some relatively low-tech products. Zheng Zheng said that enterprises should set their sights on the long-term, grasp the opportunity of a number of key national projects such as large aircrafts, improve the level of science and technology, accelerate the upgrading of product structure, and promote the faster and healthier development of China's engineering plastics industry.
The application of five engineering plastics Polyamide (PA) has earned people's attention due to its unique low specific gravity, high tensile strength, wear resistance, good self-lubricating properties, excellent impact toughness, and rigidity and softness, combined with its processing. Simple, high efficiency, light weight (only 1/7 of metal), can be processed into various products instead of metal, widely used in the automotive and transportation industries. Typical products include pump impellers, fan blades, valve seats, bushings, bearings, various instrument panels, automotive electrical instrumentation, and hot and cold air-conditioning valves, and approximately 3.6 to 4 kg of nylon products per vehicle. Polyamide has the largest proportion of consumption in the automotive industry, followed by electronics and electronics.
Polycarbonate (PC) not only has the strength similar to non-ferrous metals, but also possesses both ductility and toughness. Its impact strength is extremely high. It can't be damaged by percussion with a hammer, and can withstand the explosion of a television screen. Polycarbonates are excellent in transparency and can be colored. Due to the above-mentioned excellent properties of polycarbonate, it has been widely used in various safety lamp shades, signal lamps, transparent protective plates for stadiums, stadiums, lighting glass, high-rise building glass, automotive mirrors, windshield plates, aircraft cockpit glass, motorcycles Car driving safety helmet. The most used markets are computers, office equipment, automobiles, alternative glass and sheets, and CDs and DVDs are among the most promising markets.
Polyoxymethylene (POM) is known as "ultra-steel" because of its superior mechanical properties and chemical properties. Therefore, it can be used as a material that many metal and non-metal materials cannot handle, mainly for various precisions. High, small modular gears, sophisticated gauges with geometric surfaces, taps and valves for explosive gas pipelines. China's use of polyoxymethylene for agricultural irrigation machinery, can save a lot of copper.
Polybutylene terephthalate (PBT) is a thermoplastic polyester. Non-reinforced PBT has better processability and electrical properties than other thermoplastic engineering plastics. The glass transition temperature of PBT is low, and the mold temperature can be rapidly crystallized at 50°C. The processing cycle is short. Polybutylene terephthalate (PBT) is widely used in the electronics, electrical and automotive industries. Because PBT's high insulation and temperature resistance can be used as TV's flyback transformers, automotive distribution board and ignition coils, office equipment housings and bases, various automotive exterior parts, air conditioner fans, electronic stove bases, and office Equipment shell. Polyphenylene oxide (PPO) resin has excellent physical and mechanical properties, heat resistance and electrical insulation, and low moisture absorption, high strength, good dimensional stability, creep resistance at high temperatures is the most excellent of all thermoplastic engineering plastics. . The utility model can be applied to small household appliances such as a compressor cover, a vacuum cleaner case, a coffee appliance, a hair styling device, a massage device, a microwave oven and the like. The modified polyphenylene ether is also used in television parts, connectors for teletype end-point devices, and the like.
Vigorously develop the direction of engineering plastics 1. Improve the synthetic production capacity of engineering plastics and create core competitiveness. There are numerous blends and modified enterprises in China's engineering plastics, but the synthetic capacity is relatively insufficient. Under the strong support of the country, some domestic enterprises have introduced Technology or independent development has realized the industrial production of PA, PBT, POM, PPS, PC and other resins. China has achieved technological breakthrough in this field, but industrial transformation is still insufficient. During the twelfth five-year period, it should focus on the transfer and transformation of engineering plastics production technology, truly realize industrialization, and improve the international competitiveness of China's engineering plastic products.
2. The development of new processing technologies for engineering plastics to meet application needs. Mixing and mixing, forming, and post-processing are the general processes of polymer processing.
3. Exploit the application of engineering plastics in emerging industries. The automobile manufacturing, industrial product manufacturing, electronic appliances and consumer product packaging industries are currently the four largest application areas of engineering plastics.
4. The development of general-purpose plastics and high-performance engineering plastics, high-performance, low-cost, and general-purpose plastic engineering have been the development goals of engineering plastics in recent years.
In short, at the dawn of the "12th Five-Year Plan," China's engineering plastics enterprises should clearly and energetically develop the direction of scientific and technological innovation, improve China's engineering plastics technology level, and upgrade China's plastics industry.
