Abstract:

This paper introduced the principle and characteristics of the supercritical fluid (SCF) technology and its application progress in plastic processing. The applications of SCF in plastic microfoaming, plastic degradation, plastic modification, anhydrous dyeing, auxiliary atomization, extraction, and green plasticizing were discussed in detail. Based on the current research progress, the SCF technology can be used to resolve many problems that can hardly be overcome using the traditional technology in plastic processing. Therefore, the SCF technology exhibits a broad application prospect in the new plastic processing field. Through the utilization of the SCF technology for plastic processing, a new approach can be acquired for the green and high⁃performance development of plastic processing.

Key words: supercritical fluid, plastic processing, micro foaming, degradation, plasticizing
