The global plastic alloy market has a promising prospect

plastic alloy is the use of physical blending or chemical grafting to modify existing plastics to achieve high performance, functionality and specialization. It can improve or improve the properties of existing plastics and reduce costs. It has become one of the most active fields in the plastic industry, with rapid growth. Experts predict that with the development of economy, the world demand for plastic alloy is expected to reach 3.5 million tons around 2008

at present, general plastic alloys, such as PVC (polyvinyl chloride), PE (polyethylene), PP (polypropylene), PS (polystyrene) and so on, although still have extensive use value, because their production technology is widely mastered, some large foreign companies specially supply engineering plastic alloys with high added value

engineering plastic alloys generally refer to the blends of engineering plastics (resins), mainly including the co mixing system with PC (polycarbonate), PBT (polybutylene terephthalate), PA (nylon), POM (polyformaldehyde), PPO (polyphenylene oxide), PTFE (polytetrafluoroethylene) and other plastics as the main body, as well as ABS (acrylonitrile butadiene styrene copolymer) resin modified materials that are often classified as engineering plastics in some occasions

in recent decades, the average annual demand growth rate of plastic alloys in the world is about 10%, and 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 plastic alloys that have been industrialized 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. At present, 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

it is understood that PC/ABS, as a commercial polymer alloy with the largest sales volume in the world, can complete the modification of various experimental parameters only by using mouse and keyboard input. In 2003, the world's total output exceeded 700000 tons. In the past five years, the output of PC/ABS alloy has increased at a rate of about 10% every year, and the growth rate is in the forefront of the plastic field. At present, as long as PC/ABS operators click the mouse, alloying research has become a hot spot in polymer alloy research

pc/ABS combines the excellent properties of PC and ABS. On the one hand, it improves the heat resistance, impact resistance and tensile strength of ABS, on the other hand, it reduces the cost of PC and melt viscosity. These advantages of PC/ABS alloy make it the most widely used in the field of electronic and electrical and electronic fashion consumer goods. A typical example is the shell

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

at present, in the domestic variety structure of plastic alloy production, the production of high value-added special engineering plastic alloy is almost blank, and the reduction of inertia into the square of the reduction ratio 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 annual production capacity of plastic alloy is 700000-800000 tons, 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 produce plastic through the plastic mixing and extrusion process. Previously, they were processing enterprises responsible for the e-commerce project gold in China's 5 mines, and the processing technology level needs to be improved

due to the large market demand for plastic alloys in China, and mainly relying on imports, it is very important and necessary to develop the production of plastic alloys, improve the competitiveness of domestic resins and the level of domestic plastic processing, especially the development of engineering plastic alloys with high profits and rapid market growth, which is the top priority of China's plastic alloy industry at present
