Researchers at Qingdao University of Science and Technology have developed an integrated process–equipment–materials autoclave supercritical green foaming platform for polymers, breaking foreign dominance in high-end elastomer foaming processes and equipment. The Chinese Chemical Society's Beijing evaluation rated the project's core technologies and product performance as internationally leading. The platform has been industrialized at multiple firms, delivering about 2.1 bln yuan in incremental sales and roughly 300 mln yuan in incremental profit for partners over the past three years. The project holds 38 granted invention patents (including four in Japan), has generated 51 academic papers and established a proprietary IP system.
