TUFTEC™ H Series

TUFTEC™ H series is a fully hydrogenated SEBS that excels in weather resistance and thermal stability and is widely used as a modifier and compatibilizer.

TUFTEC™ H Series

Widely used as a compatibilizer and modifier

TUFTEC™ H series is a fully hydrogenated SEBS with excellent weather resistance and thermal stability. It is highly compatible with styrenic resins and olefinic resins and is widely used as a resin modifier, compatibilizer, and TPE compound raw material to enhance impact resistance and flexibility.

Details of TUFTEC™ H Series


Excellent weather resistance and thermal stability with a wide range of grades

TUFTEC™ H series is a SEBS in which the butadiene-derived soft block has been fully hydrogenated, resulting in exceptional weather resistance and thermal stability. The styrene-derived hard blocks aggregate at room temperature (below Tg), acting as pseudo-crosslinking points, while the hydrogenated butadiene soft blocks exhibit rubber elasticity. In particular, it is highly compatible with styrenic and olefinic resins and is used in a wide range of products to enhance impact resistance and flexibility.
