S.O.E.™

S.O.E.™ is a special SEBS with a glass transition temperature near room temperature. It excels in vibration damping, impact absorption, and wear resistance, making it suitable for a wide range of applications.

S.O.E.™

Widely used for impact absorption and wear resistance.

S.O.E.™ is a special SEBS with a copolymer-type soft block. It exhibits a wide tanδ peak near room temperature, making it ideal for various applications that require vibration damping, impact absorption, and wear resistance in this temperature range. These applications include automotive interiors, footwear, and food packaging containers.

Realizing unique properties such as vibration damping, impact absorption, and wear resistance

Unlike TUFTEC™, S.O.E.™ has a copolymer soft block, resulting in a glass transition temperature (tanδ absorption) near room temperature. This enables it to exhibit vibration damping, impact absorption, and wear resistance within this temperature range. It also boasts excellent compatibility with fillers (filler filling property). As with TUFTEC™, selective hydrogenation types are available, allowing for crosslinking. It delivers a soft touch akin to soft PVC without requiring plasticizers.
