ESSEN, Germany — Evonik Industries and the Chinese company Wynca have agreed to form a joint venture. The new company, in which Evonik will hold 60%, will produce fumed silica marketed under the AEROSIL® brand. The product is used in transparent silicones, coatings and paints, modern adhesives, and as non-combustible high-performance insulation materials. The joint venture, Evonik Wynca (Zhenjiang) Silicon Material Co. Ltd., plans to build a fumed silica production facility in the Zhenjiang New Material Industry Park (Jiangsu Province, China). The facility, with a projected annual output of 8,000 metric tons, is scheduled to become operational in 2021. The overall project still requires the approval of the relevant corporate bodies and the competent authorities.
The global market for fumed silica is growing at around 5 %, showing stronger growth than the global economy. Key drivers for the fumed silica market in China include the silicone industry for adhesives and sealants in buildings and cars as well as gel batteries such as those used in electric bikes. The joint venture will supplement Evonik's global network of AEROSIL production facilities, while Wynca plans to further expand its business with silicon-based products, using the benefits of a shared approach.
“With the joint venture, we are consistently continuing to strengthen our Resource Efficiency segment. Following the acquisition of the Huber silica business and the associated expansion of our precipitated silica capacities as well as the growth of our fumed silica capacities in Antwerp, we are now taking the next step with the first fumed silica plant in the attractive Chinese market. Wynca is a strong partner to do this, and we look forward to the future cooperation”, said Harald Schwager, Deputy Chairman of the Executive Board of Evonik Industries.
Based on synthesized organic silicon monomers, Wynca has formed a complete organic silicon industry chain from smelting cores, ganister sand processing, monomer synthesis to the final products, generating the four large product series of silicone rubber, silicone oil, silicone resin and silane coupling agent, and becoming an organic silicon company covering the full industry value chain.
“The cooperation with Evonik is a good opportunity for Wynca to realize its strategy of moving towards end products and its mission of creating better living with green chemistry. We are committed to serve the society and mankind by developing the company with circular economy, and in a resource-efficient and environmentally friendly manner,” said Jianhua Wu, Chairman of the Wynca Group.
Wynca is expanding its capacity for organochloro-silanes, which is a raw material used in the production of AEROSIL, to 300kt per annum. A small part of this capacity expansion will supply the joint venture.
