Modified plastic is the primary form of resin as the main component, to improve the resin mechanics, rheology, combustion, electricity, heat, light, magnetic and other aspects of performance additives or other resin as auxiliary components, through filling, toughening, strengthening, blending, alloying and other technical means, obtained with uniform appearance of the material.
According to the modified function, modified plastics include flame retardant resin, reinforced toughening resin, plastic alloy, functional color masterbatch and other types, each type according to different materials can be further subdivided, and due to their performance differences, application areas are also different.

modified plastics as a new material product, is a national strategic emerging industry category, the relevant national regulations and policies for the development of modified plastics technology to establish the direction. The modified plastics industry is encouraged and supported by national policies, and the relevant departments of the state pay close attention to the development of modified plastics, especially high-performance modified plastics industry, which will promote the development of modified plastics industry to continue to improve.,
China's modified plastics industry overall development level is low, the industry enterprise production scale and foreign companies in the same industry is relatively small, the product market conditions also showed low-end products, mid-range products unstable, high-end products lack of characteristics, far can not meet China's 21st century economic development needs. Therefore, modified plastics as an important part of the field of new chemical materials, has also been listed as one of the key areas of science and technology development. China's automotive modified plastics market is mainly occupied by foreign enterprises, domestic modified plastics enterprises occupy less than 1/3 of the market share. and in recent years, the introduction of automobile preferential policies has greatly promoted the development of the industry. In addition, the energy-saving emission reduction policy guidance also promotes automobile enterprises to reduce the weight of automobiles and realize energy-saving emission reduction, which greatly promotes the development of modified plastics industry. China's modified plastics industry after years of rapid development, the output and market size are showing an upward trend. From 2015 to 2021, China's modified plastic production from 13.07 million tons to 26.5 million tons. Despite the rapid development of the domestic plastics industry, the scale of plastic applications in China is still small. China's plastic modification rate (that is, the proportion of modified plastic production to total plastic production) has increased steadily. The global plastic modification rate of nearly 50%, China's plastic modification rate has been increased from 16.3 in 2011 to 21.7 in 2020, compared to the global level, there is still much room for improvement. of
new materials is the foundation of national industrial development, in recent years, in China's development of high-end manufacturing, strategic emerging industries, building a "domestic cycle" strategy and the realization of economic transformation in the context of modified plastics as an important new material types, is China's current planning of important industries, the development of domestic high-end modified plastics is China's import substitution important steps. modified plastics compared with ordinary plastics, its strengthening and toughening properties, flame retardant properties, high temperature resistance, aging resistance, scratch resistance, etc. play a vital role in the safety and stability of electronic and electrical products. By virtue of the above properties, the modified plastics have replaced the traditional metal and inorganic non-metallic materials, and become the main materials of electronic and electrical products. As people pay more and more attention to safety and health, strict requirements are put forward for the fire safety of plastic materials at home and abroad, and the future demand for high-end modified plastics will continue to grow. At present, electronic and electrical products are also developing into a new generation of products characterized by intelligence, miniaturization and modularization, and the demand for modified plastic-related products will continue to increase. China's modified plastics industry after years of rapid development, production and market size are showing an upward trend. From 2016 to 2020, China's production of modified plastics increased from 15.63 million tons to 22.5 million tons, with a compound annual growth rate of 9.54. The China Business Industry Research Institute predicts that the output of modified plastics will reach 28.84 million tons in 2022., China has thousands of enterprises engaged in modified plastics production, but the number of scale enterprises (production capacity of more than 3,000 tons) is not large. At present, the market concentration of China's modified plastics industry is low, and the top four enterprises only account for 11.5 percent of the overall market. In terms of modified plastic production, Blonde Technology accounted for the largest market share, reaching 7.1 percent. Huitong's market share reached 1.6 percent. Plitt's market share reached 1.4 percent. Guoen's market share reached 1.4 percent.
At present, most of China's new electronic and electrical consumption comes from the demand for replacement, showing the characteristics of personalization, high-end, intelligence and health. In order to present the personalized appearance of fashion and rich colors, more and more electronic and electrical production lines introduce spray-free modified plastics. Through injection molding, metal texture, natural texture, black light, flashing, extinction and other effects can be directly achieved. Emerging smart homes, smart phones, etc. not only have a thinner and more stylish appearance, but also the arrangement of their internal circuits is more compact and orderly, which also requires the shell material to meet the conditions of high glow wire, high leakage marks, etc., in order to adapt to the long-term safe operation in high temperature environment. With the continuous development of the new energy vehicle industry, China has become the world's most important supply base for new energy batteries and new energy vehicles, and new energy vehicle special materials, especially power battery materials, have put forward higher requirements for modified plastics. Modified plastics commonly used in the structure of new energy power batteries include flame retardant PPE, PPS, PC/ABS alloy and flame retardant reinforced PA. At present, most of the box materials are made of high-strength steel and light metal. Many manufacturers are trying to replace metal with SMC composite materials. This kind of modified plastic materials have good design and manufacturability, and have high strength, accurate size, corrosion resistance and good stability. Modified PPO (polyphenylene oxide) material has good corrosion resistance to lithium cobalt oxide, lithium manganese oxide and other lithium battery electrode materials, and has excellent flame retardancy, low temperature resistance and impact resistance. It is one of the ideal materials for making lithium battery protective shell. due to the development of modification technology, some general plastics can improve the original properties through modification technology, heat resistance and mechanical strength and other indicators have been significantly improved, so as to have a certain nature of engineering plastics, the application field can be greatly expanded. For engineering plastics, due to the continuous improvement of the performance requirements of raw materials in the domestic automobile, electronic and electrical industries, the original engineering plastics can no longer fully meet the downstream market requirements. After modification, engineering plastics have more excellent physical properties and are more stringent. Performance adapts to market demand. In recent years, with the continuous strengthening of independent research and development of products by upstream petrochemical enterprises in China, it has also accelerated the overall innovation of the domestic modified plastics industry. With the continuous promotion of economic transformation and industrial upgrading in China in recent years, the demand for import substitution of middle and high-end modified plastics is becoming more and more urgent, which provides a good development opportunity for the leading enterprises with strong technical strength in China.
