June 30, 2025 [Evonik]- Evonik decided to localize the final production step of its POLYVEST® ST-E 60 in Shanghai, China. This decision highlights the company’s commitment to enhancing supply security and customer proximity in Asia. The expansion is expected to be fully operational by Q3 2025.

Increasing the production capacity of silane-functionalized polybutadienes represents a significant advancement in reinforcing Evonik’s position as a reliable partner in the specialty chemicals market. By localizing and expanding global capacity, Evonik aims to meet the ongoing demand for this high-performance additive, which is critical for various applications, including rubber compounds, adhesives, coatings, tires, and sealants.

“This strategic investment will enhance our production capabilities and ensure that our customers in Asia benefit from improved supply security and shorter lead times,” says Dr. Anna Maria Ickert, Head of Evonik Coating & Adhesive Resins. “In today’s environment, fostering independent supply chains and bringing our products closer to our customers is essential, enabling us to respond more effectively to their needs.”

“This expansion aligns with our long-term strategy to strengthen our global footprint while maintaining a strong focus on sustainability and operational excellence,” says Dr. Jürgen Herwig, Head of the Evonik Coating & Adhesive Resins’ polybutadienes and specialty acrylics business. “The new capacity will enable Evonik’s customers to achieve their business goals while participating in the region’s growth. This is a crucial step toward expanding our presence in Asia.”

POLYVEST® is used as a reactive plasticizer in tire formulations. Thanks to its rubber-based nature, POLYVEST® provides a natural fit and is highly compatibility with the rubber matrix of tire tread compounds.
