Modified plastics refer to the plastic products which have been processed and modified by filling, blending, strengthening and other methods on the basis of general plastics and engineering plastics, and have improved the properties of flame retardant, strength, impact resistance, toughness and other aspects.

Modified plastics have been applied in more and more downstream fields by virtue of superior cost performance ratio. It can be said that modified plastics have become a consumption trend, and there are five factors behind this trend:

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 earthquake resistance. In addition, the improvement of the comprehensive properties of plastics provides a basis for the wide application of its downstream fields.

Low cost: compared with other materials, plastic benefits from the advantages of high production efficiency and low density, with lower cost. The cost per unit volume of plastic is only about one tenth of that of metal.

Government policy: the "3C" compulsory certification system implemented in China strictly regulates the safety performance of products in the catalogue, thus promoting the wide application of flame-retardant plastics in household appliances, it, communications and other fields.

Consumption upgrading: with the improvement of living standards, people began to pursue more excellent product performance, requiring household appliances and other products to be more beautiful, safe and durable, thus putting forward higher requirements for the upstream plastic industry, requiring better processing performance, mechanical performance, durability and safety.

Technical factors: more than 1000 kinds of polymers have been found in the world, but only a few dozen are of real application value. The development of new polymers not only has huge investment, but also has uncertain application prospects. 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 priced engineering plastics, and become the key to the development of plastic industry Effective way.
