SEPTON™ BIO-series

Kuraray developed a new family of hydrogenated styrene farnesene block copolymers (HSFC) called SEPTON™ BIO-series.

SEPTON™ BIO-series expands our range of TPE materials with a product based on natural and renewable raw materials. As a leading supplier of TPE’s, Kuraray is providing an answer to the growing need for more sustainable solutions.

SEPTON™ BIO-series is synthesized from B-farnesene, a renewable monomer derived from sugarcane. Through established fermentation processes, proprietary yeast strains convert sugar sources such as sugarcane, into B-farnesene. When B-farnesene is polymerized, its unique chemical structure provides differentiated features from conventional hydrogenated styrenic block copolymers (HSBC). When compared with HSBC’s, SEPTON™ BIO-series exhibits higher flow ability, good adhesion, lower hardness without plasticizer, good permanent and compression set, high grip performance, and improved damping properties over a wide temperature range. SEPTON™ BIO-series lends itself to a broad range of applications including: adhesives & sealants, gels, soft compounds, modifiers, nonwovens, various grips, films and foams.
