Founded in 2017, Jiangsu Sino-tech Poly. New Materials Industry Technology Research Institute is a national high-tech enterprise in Jiangsu province. The company focuses on lightweight polymer materials as its main business, and carries out technical consulting, technical research and development, testing and evaluation around 13 kinds of material systems in five major directions: general plastics, engineering plastics, special engineering plastics, thermoplastic elastomers, and bio-based plastics, also it has own production and sales of related products. At present, it has built a public service platform for supercritical foaming technology, high temperature resistant foam, special engineering plastics processing, integrated application technology, and a CNAS-qualified inspection, testing and evaluation. The products can be used in communications, LCD, advanced rail transit, military industry, new energy vehicles, aerospace and other major national strategic fields. Zhejiang Palco New Materials Co., Ltd., founded in 2018, is a "national high-tech enterprise" and "Zhejiang technology-based small and medium-sized enterprise". It has jointly established a doctoral workstation with Quzhou University. The company actively carries out scientific and technological research and innovation activities around amorphous poly (aryl ether ketone) technology and its downstream products, and is a scientific and technological innovation enterprise with innovative scientific research strength and the ability to transform scientific and technological achievements. The core technology of the company comes from the research results of Professor Zhou Guangyuan, Dalian Institute of Chemical Physics, which owns independent intellectual property rights. The construction of the amorphous poly (aryl ether ketone) project was a key deployment project of the Chinese Academy of Sciences in 2019 and passed the acceptance. Dalian Institute of Chemical Physics, Chinese Academy of Sciences, founded in March 1949, is a comprehensive research institute that attaches equal importance to basic research and applied research, combines applied research and technology transformation, and takes task-oriented discipline as its main feature. The Energy and Materials Research Department of Dalian Institute of Chemical Physics is committed to the preparation, synthesis and application research of high-performance polymer materials. At present, it has broken through the key preparation technology of high-end optical polyester PETGP, PCTG, PCT and tritan and other full series products, has the key green catalyst for PCTG synthesis, and has the ability to continuously enlarge the PCTG pilot test. Poly (aryl ether ketone) film, poly (aryl ether ketone) (ketone/sulfone) resin, high-performance poly (aryl ether ketone) foam, and poly (aryl ether ketone) thermoplastic resin matrix composites have been developed around the special engineering plastic poly (aryl ether ketone).
