The Lianhong Gerun integrated project, with a total investment of 12.5 billion yuan, has seen its 240,000 tons per year polyether polyol (PPG) production facility begin trial operations
Thread Content
On November 6, 2025, the 240,000-ton/year polyether polyol (PPG) production unit of the Lianhong Gerun integrated project began trial production, successfully completing the entire process from start to finish and producing qualified products. This major implementation project in Shandong Province has a total investment of 12.5 billion yuan and includes facilities for MTO, EVA, PO, PPC, PPG, as well as utility systems; it covers an area of over 1,600 mu. The newly commissioned PPG plant utilizes a continuously operated process developed in China. Using propylene oxide and ethylene oxide produced internally as raw materials, and dicyano metal complexes (DMC) as catalysts, it manufactures three high-performance product series: Soft Foam 330, CASE220, and CASE240.
