With SEPTON\u2122 BIO-series, Kuraray offers a unique hydrogenated styrene farnesene block copolymer (HSFC) \u2013 which makes us the first and only manufacturer of bio-based HSBC materials on the market. As one of the leading suppliers of TPEs, we are responding to increasing industry demand for more sustainable materials that can significantly improve the environmental footprint of products made with them. For example, the production of these novel TPE materials has much lower greenhouse gas emissions compared to conventional styrenic block copolymers.<\/p>\n\n\n\n

With SEPTON\u2122 BIO-series, Kuraray gives manufacturers a new solution that enables new compounds and end-uses with a high bio-based content to expand existing market areas and open up new ones. So far, Kuraray has achieved a bio content in SEPTON\u2122 BIO-series of up to 80%. Further investigations are focused on maximizing the bio-based content and finding additional synergies with other bio-based raw materials. Kuraray is continuously working on improving the physical properties of these TPE materials to open up new fields of applications for its customers.<\/p>\n<\/div>\n\n\n\n

How it\u2019s made<\/h2>\n\n\n\n

SEPTON\u2122 BIO-series is a new family of hydrogenated styrene farnesene block copolymers (HSFC), which is based on natural, renewable resources. SEPTON\u2122 BIO-series utilizes a new, bio-based monomer called beta-farnesene, which is derived from the fermentation of sugar from sugar cane. Through established fermentation processes, proprietary yeast strains convert sugar sources into beta-farnesene. When beta-farnesene is polymerized, its unique chemical structure differs from conventional hydrogenated styrene block copolymers (HSBCs). SEPTON\u2122 BIO-series thus allows the development of TPEs that are more sustainable than conventional materials on the market and enables users to increase the bio content of TPEs compared to petroleum-based materials.<\/p>\n<\/div>\n\n\n\n
