German chemical firm Evonik says it has decided to localise the final production step of its Polyvest ST-E 60 polybutadienes 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.
Polyvest is used as a reactive plasticiser in tyre formulations. Thanks to its rubber-based nature, it provides a natural fit and is highly compatibility with the rubber matrix of tyre tread compounds.
By increasing the production capacity of silane-functionalised polybutadienes Evonik says it aims to meet the ongoing demand for this high-performance additive, which is used for various applications, including rubber compounds, adhesives, coatings, tyres, 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 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.”
