SEPTON™ is a series of styrenic thermoplastic elastomers developed by Kuraray. SEPTON™ is used in a great number of TPE compounds and can be processed in a wide variety of forms. Specific grades are certified and used in consumer goods, medical, mobility and oil modification applications. These styrenic TPEs cover a broad range of applications including compounds, polymer modification, adhesives, flexible PVC substitutes and vibration damping products.
The Hydrogenated Styrenic Block Copolymers (HSBCs) consist of styrene-based hard blocks and a hydrogenated diene soft block. HSBCs exhibit rubber-like elasticity since the hard block acts as a crosslinking point below the glass transition temperature of polystyrene and the soft block provides elasticity. Hydrogenation generates excellent heat and weather resistance.
SEPTON™ is offered in a variety of grades, from low to high styrene content and from low to ultra-high molecular weight. Also, in terms of soft-block structure, there are four different types, SEP, SEPS, SEEPS and SEBS.
There is a variety of SEPTON™ grades, from low styrene content (soft) to high styrene content (rigid), from low molecular weight (high flow) to high molecular weight (more rubber-like properties). Each provides different functional characteristics and can be used in various applications. These products exhibit rubber-like properties over a broad temperature range. In comparison to non-hydrogenated styrenic block copolymers, SEPTON™ exhibits better tensile strength, better heat, weather and ozone resistance as well as better compatibility with polyolefins.
