On September 25, 2025, Wanhua Chemical Group announced that its organic silicon intermediate project had been successfully put into operation, and the first batch of qualified products had passed downstream customer certification, marking a key step in the strategic layout of this global chemical giant in the field of organic silicon. The project is located in Yantai Chemical Industry Park, Shandong Province, and adopts internationally leading fluidized bed reactor technology. The unit energy consumption is reduced by 20% compared to traditional processes, and the product purity reaches 99.99%. It can be widely used in fields such as nursing supplies, automotive seals, medical catheters, and electronic and electrical packaging.


Technological breakthroughs and market impact
According to the project leader, WANICONE, independently developed by Wanhua Chemical ® The series of organosilicon intermediates achieves precise regulation of the siloxane chain through molecular design technology, making the product highly elastic, heat-resistant, and biocompatible. For example, its medical grade silicone rubber catheter material has a tensile strength of 12MPa and has passed ISO 10993 biocompatibility certification, which can meet the stringent requirements of high-end medical equipment such as insulin pumps. Market data shows that after the project is put into operation, Wanhua Chemical will become one of the top five global suppliers of organic silicon intermediates, with an expected annual output value of over 1.5 billion yuan, driving an increase of 3 billion yuan in downstream industrial chain output value.


Industry background and policy drivers
This production coincides with a critical period of "green restructuring and technological fission" in China's organic silicon industry. In July 2025, the world's first 10000 ton bio based silicone rubber production line will be put into operation in Shandong, completely eliminating dependence on petroleum raw materials; At the same time, the European Union launched a "carbon footprint tracing" investigation on Chinese photovoltaic adhesive products, forcing domestic enterprises to accelerate their low-carbon transformation. The Ministry of Industry and Information Technology's "Action Plan for High Quality Development of New Materials Industry in the 15th Five Year Plan" clearly requires that the energy consumption of newly built organic silicon monomer units must be 20% lower than the industry average. The Wanhua Chemical Project is a practical example of this policy.


Expert opinions
Liao Jun, Vice Chairman of the China Fluorosilicon Organic Materials Industry Association, pointed out that "the production of Wanhua Chemical not only improves its integrated industrial chain of 'propylene epoxy propane polyether polyol organosilicon', but also promotes the overall energy efficiency improvement of the industry through technology spillover effects. It is expected that by 2028, the proportion of high-end organosilicon products in China will increase from the current 30% to 45%, and the market share of enterprises that master core technologies will exceed 70%
