The production base of Suzhou Ke Sheng Tong is nearly 25,000 square meters under stable production. At the same time, at the beginning of 2022, bid for 18,000 square meters land in the Chemical Industry Park of Shanxian County, Heze City, Shandong Province, and invested in the establishment of Shandong Lianrui Biotechnology Co., LTD. (registered capital of 10 million yuan). We plan to build a project with annual production capacity of 1500 tons/year of high-performance anti-hydrolysis agent and 3000 tons/year of special chain extender. All new projects will adopt the most advanced and pollution-free process route at home and abroad. The project is under intense construction, and is expected to be completed and start production from October 2023. Once the plant finish, the economic indicators of Suzhou Ke Sheng Tong will be greatly improved, and will also build a solid foundation for creating the invisible champion in the subdivision field in the future.
