Modified plastic refers to the addition of suitable modifiers on the basis of general-purpose plastics and engineering plastics. It is processed by filling, blending and strengthening to obtain novel structural features and improve flame retardancy, strength and impact resistance. Plastic products with properties in terms of properties, toughness, etc. Modified plastics can be classified into flame retardant resins, reinforced and toughened resins, glass fiber reinforced thermoplastics, plastic alloys, and pvc alloy products according to their functional classification. As an important part of the new chemical materials field, modified plastics have been included in the key scientific and technological fields.

The development of China's modified plastics industry began in the 1990s. Before that, China's modified plastics basically needed to be imported from abroad. In the early stage of industry development, domestic modified plastics enterprises mainly use their own labor cost advantages to seize the middle and low-end products market. After nearly 20 years of rapid development, China's modified plastics industry has gradually grown up with a number of well-known enterprises with independent research and development capabilities, the innovation ability of new products and the stability of mass production have been greatly improved, some modified plastics In the formulation, process and other aspects have reached the international advanced level.
Modified plastics overcome the defects of poor heat resistance, low strength and toughness, and weak wear and impact resistance of ordinary plastics. At the same time, they also impart new characteristics such as flame retardant, weathering, antibacterial and antistatic, and these superior comprehensive properties. It has been used more and more widely in the downstream field, which has greatly promoted the development of the plastics industry and new materials.
With the influence of the trend of “plasticizing steel†and “lightweight automobile, light and thin household appliancesâ€, and the gradual implementation of policies such as “new urbanization†and “building beautiful Chinaâ€, the application products of this industry will be further expanded. Enterprise technology upgrades and innovations and product structure optimization and adjustment have brought broad development prospects to the industry.
Modified plastics have the advantages of high performance and low cost, and at the same time have national policy support, which is the need of consumption upgrade, and also has technical feasibility. Now its application scope has been extended to many fields such as construction, packaging, home appliances, automobile accessories, electronic and electrical, power tools, toys, lighting and office equipment. It has broad development space and is the direction of the transformation and development of the traditional plastic products industry in the future.
