Any physical, mechanical and chemical effects can be made to improve the original performance of the resin can be called plastic modification. The meaning of plastic modification is very wide, in the modification process, which can occur physical changes, chemical changes can occur. Plastic modification of a wide range of applications, almost all of the plastic properties can be modified by modified methods, such as plastic appearance, transparency, density, precision, processability, mechanical properties, chemical properties, electromagnetic properties, corrosion resistance Performance, aging resistance, abrasion resistance, hardness, thermal properties, flame retardancy, barrier properties and cost and so on.

Plastic modification is another simple and effective method of obtaining new performance resins besides the polymerization method. Since 1909 the German Bakkeite synthesis of the first resin variety - a phenolic resin since the development of new plastic resin is very fast. According to incomplete statistics, up to now, more than 10,000 kinds of resins have been reported, and no fewer than two hundred kinds of resins have been put into commercial production and put into practical application. However, in recent years, the development of new varieties of resins is getting slower and slower, mainly because most of the varieties that can be developed have been developed. to this end. People have shifted their eyes to the development of new resin varieties to modify the original resin, thus expanding the original resin applications.
