Sichuan Zhengdakai New Materials Co., Ltd. is located in Xuanhan, Dazhou. It was invested and built by Zhink Group in response to the new round of East&West Cooperation and its own industrial development needs. The project uses natural gas as raw material and adopts internationally advanced production technology. Phase I is the construction of a project involving 600,000-ton annual production of ethylene glycol and 100,000-ton electronic-grade DMC. Phase II is the construction of downstream supporting industrial projects involving 600,000-ton annual production of ethylene glycol, oxalic acid, liquid ammonia, and others, which is planned to be completed. The project will enhance the coordinated development of related upstream and downstream industries such as petrochemicals, new materials, packaging, and textile fibers in Sichuan and the central and western regions after operation, and foster the natural gas chemical ecological industrial cluster by integrating regional resource advantages.

As a collaborative industry of the group, Zhink Group has successfully developed and built high-quality projects such as Xiaoshan Chamber of Commerce Building, Haining Lingyu Jingdu Mingting (Phase I and Phase II residences) and Noble Center for the past decade. Currently under construction, "One of the 100 Billion Projects in Zhejiang Province", the Nord Intelligence Center integrates diversified commercial carriers such as hotels, high-end office buildings, and hardcover apartments, becoming another new landmark on the north shore of Hangzhou Bay.
