The modified plastic industry system in China has been gradually improved
Modified plastics refer to plastic products that use filling, reinforcement, blending, and other methods to process general plastics and engineering plastics, in order to improve their mechanical, toughness, flame retardancy, and other properties.
General plastic engineering. Modified plastics have excellent performance and irreplaceable status in many fields. However, we have to face one thing. At present, modified plastics are not only far higher than the price of general plastics in the market, but also far lower than the output of general plastics in the output. This is still a comparison under the premise of reducing costs by expanding production facilities for modified plastics. That is to say, with the development of modification equipment and the progress of modification technology, general-purpose plastics such as polypropylene PP, acrylonitrile butadiene styrene block copolymer ABS, etc. have improved their strength, heat resistance and other performance indicators through modification, possessing certain characteristics of engineering plastics, but with significant advantages in price, thus being able to seize some of the application markets of traditional engineering plastics.
High performance engineering plastics. With the development of industry in our country, especially in the automotive, electronic and electrical, and mechanical industries, people's requirements for material properties are constantly increasing. Therefore, existing engineering plastic varieties, such as polycarbonate PC, nylon PA, polyester PBT and PET, polyphenylene oxide PPO, etc., can no longer meet market demands. As a result, developers are developing engineering plastics with higher performance, such as those used for energy-saving lamp bases that require high temperature resistance and yellowing resistance, those used for chip trays that require resistance to bending and static electricity, those used for electronic connectors that require high flame retardancy, high heat resistance, and high flow resistance, and those used for mechanical gears that require wear resistance, high rigidity, and high dimensional stability.
Low cost of special engineering plastics. Special engineering plastics refer to engineering plastics that can be used for a long time at 150 ℃ or above, such as PPS, PIM, PEEK, PSF and other special engineering plastics. Special engineering plastics generally have good electrical properties, high temperature resistance, and dimensional stability. Some also have good flame retardancy, radiation resistance, chemical resistance, and mechanical properties. Therefore, they are widely used in industries such as high-tech, military, aerospace, and aviation. However, one thing is that the market price of special engineering plastics is often several times that of ordinary engineering plastics, which is acceptable in military products. For civil products, it is necessary to maintain its high performance and relatively low price.
The modified plastic industry is a typical industry that benefits from technological progress and consumer upgrading. Its downstream products are also mostly concentrated in industries such as home appliances, automobiles, electric tools, and toys. With its cost advantages in labor and other production factors, China has become a major manufacturing country in these fields and has driven the development of the domestic modified plastic industry; The upgrading of consumption has brought China's automotive, construction and other industries into a period of rapid growth. With the continuous improvement of material performance requirements, China is becoming the largest potential market and main driving force for global demand growth for modified plastics. Professional modified plastic manufacturers meet the growing demand through technological progress, with broad development space.
