Shandong Dongyue Chemical Co., Ltd.

Around the cause of green environmental protection, the company joined hands with Tsinghua University and Dongyue Tsinghua to win the national technological invention award for the first series of green refrigerants R4 15a and R4 18a, which were approved and promoted by the US SNAP program and obtained the international uniform number. At the same time, we are committed to the research and development of polymer materials. Ten thousand tons of PTFE and its polymers, which integrate advanced technologies at home and abroad, have passed the expert appraisal, filling six gaps in China, ending the history that China's fluorine chemical polymer materials mainly rely on imports and low-grade small-batch production, reaching the world advanced level.
