Wanhua Rongwei Co., Ltd is a subsidiary of Wanhua Chemical Group, specifically part of the Polyol Business Unit. Wanhua Chemical has three major production bases located in Yantai, Ningbo, and Foshan. It is the largest polyols supplier and service provider in terms of production capacity, with the most diverse product portfolio and a well-established industry supply chain. Wanhua is also the largest exporter of polyether polyols in China.

In order to fully leverage the synergies between polyether polyols and MDI/TDI, Wanhua Group aims to further expand its market share in polyether polyols, enhance its brand image, and consolidate its dominant position in the polyether polyols industry.

Against this background, leveraging the advantageous port location, public infrastructure, and industrial chain advantages of Ningbo Daxie Development Zone, Wanhua Chemical (Ningbo) Rongwei Polyurethane Co., Ltd. continues to expand its production capacity based on the operational experience of its existing polyether polyols plant. Its annual production capacity of polyether polyols will be increased from 110 ktpa to 280 ktpa through the expansion project, aiming to meet the demand for polyurethane raw materials and lead the industry’s long-term stability and development, while establishing a new brand presence for Wanhua in the polyurethane industry. Currently, Wanhua’s 280kt polyether polyols expansion and transformation project has been completed and the commissioning phase has begun, scheduled from July 1, 2023, to October 1, 2023.

As of 2023, Wanhua’s total capacity of polyether polyols reached 1.23 mtpa. Furthermore, Wanhua Chemical Group announced a 850 ktpa polyether polyols expansion project at the end of 2021. This includes a 120kt ordinary flexible slabstock polyols production line, a 120kt flexible high resilience polyols production line, a 72kt differentiated polyols production line, a 58kt PPG230 polyols production line, a 240kt polymer polyols (POP) production line, a 240kt continuous DMC polyols production line, as well as supporting public works and facilities for storage, transportation and environmental protection. With these expansions, Wanhua Chemical’s total production capacity of polyether polyols is expected to exceed 2 mtpa.
