In March 2026, plastic modification technology, a key means for the upgrading and optimization of general plastics, has become a focus in the high-end manufacturing field. Plastic modification optimizes and improves the performance of general plastic resins through physical, chemical, mechanical and other methods, and even endows them with new functions such as conductivity, antibacterial property and degradability. It can not only enhance the strength, heat resistance and flame retardancy of plastics, but also reduce production costs while ensuring performance, becoming the core technical support for plastic parts in automobiles, 3C electronics, high-end home appliances and other industries. At present, the mainstream plastic modification methods are mainly divided into four categories. Among them, additive modification is the most common method due to its low cost and wide application, which can meet various needs such as cost reduction, reinforcement and toughening. Blending modification realizes performance complementation through resin blending; composite modification and surface modification optimize performance from the aspects of structural composite and surface treatment respectively. High-end modification processes also integrate a variety of methods to find the best balance among performance, cost and processing technology.
