Zeon and Visolis Sign Agreement for Bio-Isoprene Development

TOKYO/HAYWARD — In a significant move toward decarbonizing the elastomer supply chain, Zeon Corporation and Visolis have announced a Memorandum of Understanding (MOU) to jointly develop and commercialize bio-isoprene. The agreement, signed on February 16, 2026, combines Zeon’s expertise in polymerization and materials science with Visolis’ advanced biomanufacturing capabilities.

Accelerating the Shift to Bio-Elastomers

Isoprene is a fundamental monomer used in the production of polyisoprene (synthetic natural rubber), styrene-isoprene-styrene (SIS) block copolymers, and other high-performance elastomers found in tires, adhesives, and medical products. Traditionally, isoprene is extracted as a byproduct of naphtha cracking, a fossil-fuel-intensive process.

This collaboration aims to replace petrochemical feedstocks with biomass-derived alternatives without compromising material performance. By leveraging bio-isoprene, Zeon seeks to drastically reduce the carbon footprint associated with its downstream rubber and latex products, addressing the growing demand from automotive and consumer goods sectors for sustainable raw materials.

Synergistic Technologies

The partnership utilizes Visolis’ proprietary production platform, which integrates synthetic biology with chemical catalysis. Visolis has developed a high-efficiency fermentation process capable of converting renewable biomass into bio-isoprene monomers at a scale viable for industrial applications.

Zeon Corporation brings decades of experience in the commercialization of synthetic rubbers and specialty resins. Under the agreement, Zeon will focus on the polymerization technology required to process Visolis’ bio-monomers into high-grade elastomers. The companies plan to validate the material properties of the resulting bio-rubbers to ensure they meet the rigorous durability and elasticity standards required by industrial clients.

Strategic Roadmap for Carbon Neutrality

This agreement aligns with Zeon’s medium-term management plan, which emphasizes the transition to a circular economy and the achievement of carbon neutrality by 2050. By securing a reliable technology for bio-isoprene production, Zeon aims to stabilize its supply chain against the volatility of fossil fuel markets while expanding its portfolio of eco-friendly “C5” chemical derivatives.

The companies are expected to move from feasibility studies to pilot-scale production within the coming year.
