Modified plastics have been applied in more and more downstream fields due to its superior cost performance. It can be said that modified plastics have become a consumption trend, and the trend implies the following five factors:
　　High performance: the modified plastics not only have the advantages of traditional plastics, such as low density, corrosion resistance, etc., but also have good physical and mechanical properties, such as high strength, high toughness, high impact resistance, wear resistance and seismic resistance. In addition, the improvement of comprehensive properties of plastics provides the basis for its wide application in downstream fields.
　　Low cost: compared with other materials, plastics have lower cost due to the advantages of high production efficiency and low density. The cost of plastics per unit volume is only about one tenth of that of metals.
　　Government policy: China's "3C" compulsory certification system strictly regulates the safety performance of products in the catalogue, thus promoting the wide application of flame retardant plastics in household appliances, it, communication and other fields.
　　Consumption upgrading: with the improvement of living standards, people begin to pursue more excellent product performance, requiring home appliances and other products to be more beautiful, safe and durable, thus putting forward higher requirements on the upstream plastic industry, requiring it to have better processing performance, mechanical properties, durability and safety.
　　Technical factors: at present, more than 1000 kinds of polymers have been found in the world, but there are only dozens of them with real application value. The development of new polymers is not only a huge investment, but also the application prospect is not clear. On the contrary, the modification technology can not only improve the performance of existing polymers to meet the needs of the industry, but also reduce the cost of some high price engineering plastics and become the development of plastic industry Effective way.
　　Modified plastics are intermediate products in the petrochemical industry chain. They are mainly made of five general-purpose plastics and five engineering plastics. They are flame retardant, impact resistant, high toughness and easy to process. Modified plastics is a typical industry benefiting from technological progress and consumption upgrading. Thanks to the accelerated transfer of global production capacity of household appliances, computers, power tools and toys to China, China has become a big manufacturing country in these fields with its cost advantages in labor and other production factors, which has promoted the development of domestic modified plastics industry. Consumption upgrading makes China's automobile, construction and other industries enter a period of rapid growth. With the continuous improvement of material performance requirements, China is becoming the largest potential market and main demand growth power of modified plastics in the world.
