This process technology passed the appraisal organized by China National Light Industry Federation in April 2019. The appraisal committee is composed of well-known professors and industry experts from key national universities such as Tsinghua, Fudan, and Zhejiang University. The director is Qu Jinping, an academician of Chinese Academy of Engineering. The appraisal conclusion is that the two-stage continuous extrusion foaming integrated process technology developed by the project is innovative and advanced. The overall technology of the project has reached the international advanced level, and some technologies have reached the international leading level.
