Because of the limitations of single resin performance, and people's requirements for low-cost, high-performance and performance diversification of materials are getting higher and higher, various engineering plastics modified varieties came into being. This paper analyzes the modification trend of engineering plastics and their wide application in automobile, electronics, electricity, communication, transportation, aerospace, machinery and other fields.


Engineering plastics refer to a kind of plastics that can be used as engineering structural parts. Because of its obvious advantages such as low density, high specific strength, excellent wear resistance, low friction coefficient, high heat resistance, electrical insulation, chemical stability, acid / alkali resistance, free coloring, easy modification and good processability, they are widely used in the fields of automobiles, electronics, electricity, communications, transportation, aerospace, machinery and so on, It has become one of the important symbols to measure a country's industrial development level.

Modification can significantly improve the properties of engineering plastics, and make a polymer matrix produce products with different uses.
