Meeting consumers’ needs with Kuraray’s elastomers

Kuraray manufactures styrenic block copolymers under the trademarks of SEPTON™ and HYBRAR™. These styrenic thermoplastic elastomers (TPE) cover a wide range of applications including: � Compounds: automotive, consumer products and vulcanized rubber replacement � Polymer modification: impact modifier and compatibilizer � Adhesives: hot melts � Flexible PVC substitutes � Vibration damping products The Hydrogenated Styrenic Block Copolymers (HSBCs) consist of styrene based hard blocks and a hydrogenated diene soft block. The combination of the blocks means HSBCs exhibit rubber elasticity. The hard block acts as a crosslinking point below the glass transition temperature of polystyrene while the soft block provides elasticity. In addition, hydrogenation provides excellent heat and weather resistance. SEPTON ™ and HYBRAR ™ Technical Information

� SEPTON TM and HYBRAR TM 1

SEPTON TM – High-Performance TPE SEPTON™ is a series of styrenic thermoplastic elastomers used in a great number of TPE compounds and can be processed in various forms. These styrenic TPEs cover a broad range of applications including compounds, polymer modification, adhesives, flexible PVC substitutes and vibration damping products. Specific grades are certified and used in consumer goods, medical, mobility and oil modification applications. SEPTON TM BIO-series – Bio-based TPE With SEPTON™ BIO-series, Kuraray offers a unique Hydrogenated Styrene Farnesene Block Copolymer (HSFC) – making us the market’s only bio-based HSBC manufacturer. 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. SEPTON TM Specialty Grades Using its proprietary polymer synthesis and modification technologies, Kuraray has developed several unique grades of SEPTON™. Those series cover a broad range or product properties including being super soft and having superior heat resistance.

SEPTON™ Q-series is a range of thermoplastic elastomers that combines softness and elasticity.

SEPTON™ V-series is a block copolymer with reactive and cross- linkable hard and soft block.

SEPTON™ J-series is Kuraray’s specialty product for high performance gels.

2 SEPTON TM and HYBRAR TM �

HYBRAR™ is a truly unique block copolymer consisting of polystyrene end blocks and a vinyl bond rich poly-diene mid- block. Due to its peak tan delta over a broad temperature range, HYBRAR™ exhibits high vibration damping and shock absorption properties. Unlike PVC and other SBCs, products manufactured using HYBRAR™ do not need a plasticizer. The highly elastic styrenic block copolymer HYBRAR™ can be processed in a wide variety of forms, including films, tubes, foams, and injection molding. HYBRAR™ products are available as hydrogenated and non- hydrogenated grades. Hydrogenated grades of HYBRAR™ have excellent compatibility with polypropylene resulting in excellent transparency and clarity when blended.
