Plastics play an important and irreplaceable role in many aspects of our daily lives, industry and agriculture. If ordinary plastics are modified, new properties can be added to the plastics, or some of the original properties can be significantly improved, and the use of plastics can be further expanded. The modification of plastics is achieved by two methods: physical modification and chemical modification. Modified plastics show excellent mechanical properties and are widely used in electronics, electrical parts, mechanical parts, auto parts and other industries. The modification of engineering plastics tends to add suitable modifiers to the modified plastic materials, and realize the modification of plastics through certain processing and molding processes, and produce new plastic materials and products with new structure and excellent performance.

The important position of engineering plastics modification in plastics industry:

In the 1980 s, China's plastic modification technology developed rapidly. The modification of engineering plastics has been widely concerned by many researchers, and the research and development of engineering plastics is in full swing. By the 1990 s, engineering plastics modification research began to enter the industrialization stage. So far, millions of enterprises have been committed to the development and production of blended engineering plastics, with a total production capacity of 200000 tons, forming a new plastic material industry with a certain scale. As the market demand for engineering plastics products increases year by year, China's engineering plastics materials industry continues to maintain a rising momentum. Among them, by 2005, the total demand for engineering plastics for various railway and highway construction in the automobile industry is about 4.5 million tons, and the demand for various plastic accessories and materials such as post and telecommunications, communication cables and the like can reach 40 tons, which indicates that China's engineering plastics blending modification technology will be vigorously developed.

With its excellent performance, low price, easy and practical characteristics, engineering plastics can solve the national economy, national defense construction, industry, agriculture, daily life and other fields more quickly and economically, as well as provide colorful new materials for decorating daily cultural life. It is an important means for people to obtain new engineering plastic materials, especially when a single material cannot meet our requirements, plastic modification means are becoming more and more important. The progress of engineering plastics modification technology can not only promote the development of plastic materials industry and plastic products industry, but also prosper the fields of polymer materials and composite materials science and engineering. Therefore, it has been paid more and more attention by industry and academia.
