Plastic alloy in the world of applications is very extensive. Research and development of production of foreign plastics modification quickly, many of the international market, the supply of plastic raw materials is a modification of Special Material grades, these Special Material grades easy to use, stable performance, well received by the plastics processing industry welcomed to compete in the market vitality. It can be said that the development of plastic alloy production, improve the competitiveness of domestic resin and the level of domestic plastic processing, to meet the needs of international industry is of great significance.
At present, the common plastic alloy (such as PVC.PE, PP, PS alloy) Although there are still widely used value, but may be because of its production technology basically grasp, so in foreign countries, the company specializes in the supply of engineering plastics alloy varieties . Engineering plastics alloy refers to blends of engineering plastics (resin), including the PC, PBT, PA, POM, PPO, or the PPE, PTFE and other plastic-based blends, as well as engineering plastics in some cases is often attributable to ABS resin.
The development of plastic alloys can play a more rich variety of plastic products to improve or enhance the performance of the existing plastic, functional performance, lower cost, ease of processing and reduce environmental pollution and other aspects of the role. Therefore, it has become one of the most active areas in the plastics industry. Plastic alloy products are widely used in automotive, electronics, precision instruments, office equipment, packaging materials, building materials and other fields.
Foreign Market Analysis and Forecast
Plastic alloy for major development in 1966, the U.S. company GE high-impact PS, PPO was modified to solve the key technology of of PPO difficult molding, and lower costs, start mass production of goods called NOryl modified PPO (MPPO) resin. In 1976, the United States DuPont success ZytelST development super-toughness nylon series, which is a high impact strength plastic alloy, it was first made of ductile polymers, obtained by the toughness of polymers and nylon 66 blend. Compared to nylon 66, ZytelST impact strength can be increased by more than 10 times. Since then, DuPont has developed a successful super-tough POM and super-tough alloy varieties to enhance PET and other polymers.
In the mid-1960s, the United States BrogWarnerChemicals company developed the first PC / PA alloy, because of its excellent heat resistance, impact resistance, dimensional stability and good molding processability, so in recent years, rapid development. 1984, the U.S. company GE successful development of the PPO / PA new plastic alloys, trade names NorylGTX. Which is characterized by the use of compatible technology, and compatibility of non-crystalline resin, PPO and crystalline resin PA, so that the alloy combines the advantages of PPO and PA.
In the 1980s and 1990s, plastic alloy, the average annual growth rate of 10%, while the growth rate of engineering plastics alloy up to about 15%. The United States, Europe, Japan has industrialized plastic alloy varieties of plastic alloy, engineering plastics, Department of the vast majority of alloying has become the main method of modified engineering plastics.
The world market for plastic alloy consumption is about 1.75 million tons in 1997, it is estimated that the world of plastic alloy total consumption of over 2.6 million tons in 2004. From a regional perspective, North America is the largest consumer region, accounting for 45%; followed by Europe, accounting for 34%; Japan and the Pacific accounted for 21%. The PPO alloys in North America, accounting for more than 25% of the demand for plastic alloy, especially in the PPO / PA, the PPO / PET and PPO / PBT greatest demand; more than 12% of the total demand of the PC alloy; for automotive end-use ABS alloy (9.9%) proportion.
The largest user of plastic alloy automotive parts, mechanical and electronic components. Plastic alloy to save costs, improve performance can be used as a substitute for other materials (such as glass, metal, wood and other plastics); With economic development, automobiles, electronic appliances, daily necessities market activity, demand for plastic alloys increased accordingly. Expected world demand for plastic alloy before and after 2008 will reach 3.5 million tons.
Domestic market analysis and forecasting
Of plastic alloys (excluding foreign-funded enterprises) in both research and production are still in the scattered state, not yet formed a scale, the lower the level of industry as a whole, a far cry from foreign advanced level.
2004 China has more than 300 plastic alloy manufacturers, it is estimated that plastic alloys (containing the modified pellets) 700 000 -80 tons / year production capacity, production is estimated to reach 60 million tons. But among the larger, only 15%, 15% enterprise production accounts for more than 70% of the total output.
Production structure of the varieties of domestic plastic alloy, the production of high value-added specialty engineering plastics alloy is almost a blank, the basic common plastic alloys and modified products production, most of these enterprises through the plastic compounding extrusion process for the production of plastic alloy and processing enterprises. In the production of varieties of alloy species: the PPO class in the PPO / PS-PC, PC / PBT, the PC / ABS, the PC / PA, the PC / PE, PA, class of super-tough nylon (PA / EPDM) , the PA / PP, the PA / SBS / petroleum resin etc.. From the overall structure of the products of China's 60 million tons of plastic alloys (containing modified resin) flame-retardant resin accounted for 45 percent, accounted for 25% of reinforced resin, toughened resin accounted for 15%. China plastic alloys (containing modified resin), the total consumption of approximately 120-140 million tons, the domestic supply of only 600,000 tons, the annual import volume of up to 90 million tons.
Expected in 2008, China's top five general-purpose engineering plastics demand will reach 100 million tons, five synthetic resin demand will reach 42 million tons. With the development of science and technology, the applications of polymer materials continue to broaden all walks of life are required to improve the material, the existing synthetic resin is difficult to meet the requirements, plastic modification is to provide new materials, the most practical and economical means of .
