The hottest plastic alloy industry in China urgent

  • Detail

China's plastic alloy industry urgently needs a breakthrough

plastic alloy is a new class of high-performance, functional and specialized materials obtained by physical blending or chemical grafting. Plastic alloy products can be widely used in automotive, electronics, precision instruments, office equipment, packaging materials, building materials and other fields. It can improve or improve the performance of existing plastics and reduce costs, and has become one of the most active varieties in the plastic industry, with a very rapid growth. China's plastic industry should recognize the situation, identify the gap, seize the opportunity, increase scientific and technological investment, speed up the development of the plastic industry, and strive to catch up with the world development level

the world's demand for plastic alloys surged

in 1997, the world's plastic alloys were combined to form a circular "balloon" with uniform wall thickness when inflated, and the market consumption of gold was about 1.75 million tons. It is estimated that the total consumption of plastic alloys in the world this year will exceed 2.6 million tons. With the rapid economic development, it is expected that the world demand for plastic alloys will reach 3.5 million tons around 2008

at present, the largest user of plastic alloy products in the world is automotive parts, followed by mechanical and electronic components. From the demand structure of major engineering plastic alloys in Japan, it can be seen that plastic alloys for automobiles account for 62%, electronic, electrical and office automation equipment account for 20%, general precision machinery accounts for 6%, and medical treatment, sports and others account for 12%. In terms of regions, North America is currently the largest plastic alloy consumption region, accounting for 45%; The second is Europe, accounting for 34%; Asia and the Pacific account for 21%. In North America, PPO (polyphenylene oxide) alloys account for more than 25% of the total demand for plastic alloys, especially PPO/PA (polyamide), PPO/PET (polyethylene terephthalate) and PPO/PBT (polybutylene terephthalate) alloys; PC (polycarbonate) alloy accounts for more than 12% of the total demand; ABS alloy used for automotive end use accounts for 9.9%

the hottest market for engineering plastic alloys

at present, it is impossible to have plastic alloys with slip signs, such as PVC (polyvinyl chloride), PE (polyethylene), PP (polypropylene), PS (polystyrene) alloys. Although they are still widely used, their production technology is widely mastered, so in foreign countries, major companies specialize in supplying engineering plastic alloys with high added value

engineering plastic alloys generally refer to the blends of engineering plastics (resins), mainly including the blends based on PC, PBT, PA, POM (polyoxymethylene), PPO, PTFE (polytetrafluoroethylene) and other engineering plastics, as well as ABS resin modified materials

in recent decades, the average annual demand growth rate of plastic alloys in the world is about 10%, among which the growth rate of engineering plastic alloys with the highest added value is as high as about 15%, which has become a variety actively developed by multinational companies. Among the industrialized plastic alloys in the United States, Europe and Japan, engineering plastic alloys account for the vast majority, and alloying has become the main method of modifying engineering plastics at present. However, there are few varieties and poor quality of engineering plastic alloys in China, and the annual import volume accounts for more than 60% of the total demand

pc/ABS, as the commercial polymer alloy with the largest sales volume in the world, has been widely used in the field of electronics and electrical and fashion consumer goods. In 2003, the world's total output exceeded 700000 tons. In the past five years, the output of PC/ABS alloy has increased by about 10% every year, and its growth rate ranks in the forefront in the field of plastics. At present, the research on PC/ABS alloying has become a hot spot in polymer alloy research

the broad market attracts many competitors. Bayer, teiren Huacheng, Mitsubishi, etc. have developed many mature products one after another. China has also become an arena for international chemical giants, and the products of foreign companies occupy 90% of China's market. Although domestic researchers have done a lot of research work, the quality and quantity of products cannot be compared with international chemical giants. Domestic researchers and market developers still have a long way to go

domestic R & D and production levels need to be improved

China's research on plastic alloys has developed rapidly in recent years since the 1960s. According to statistics, at present, the total 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 600000 tons, and the annual import volume is as high as about 900000 tons; Moreover, plastic alloys (mainly mixed resins and modified resins) in China are mainly used in household appliances, electronics, automobiles and other industries. Compared with developed countries, China's plastic alloy application market still has a lot of room to expand

with the sustained and high-speed development of China's economy, the plastic alloy Market in China has great potential in the next few years, especially the rapid growth of electronic communication, automobile and construction industries, which will drive the rapid development of China's engineering plastic alloy industry. It is estimated that by 2008, the total demand for the five major engineering plastics in China will reach 1million tons, and the demand for the five major synthetic resins will reach 42million tons, which will become one of the largest importers of plastic alloys in the world

at present, the research and production of plastic alloys in China are still in a scattered state, which has not yet formed a scale, and 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 alloy is almost blank, which is basically the production of general plastic alloy 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 alloy (including modified pellets) is 700000 ~ 800000 tons/year, and the output is about 600000 tons/year. However, only 15% of them are large-scale enterprises, and the output of these 15% enterprises accounts for more than 70% of the total output of plastic alloy in China. Most of the enterprises are processing enterprises that produce plastic alloy through plastic mixing and extrusion process. The level of research and development and processing technology of plastic alloys in China needs to be improved urgently
