TUFTEC™ P Series

The TUFTEC™ P series is a special type of styrene-based thermoplastic elastomer (SBBS) with selective hydrogenation. It offers excellent low-temperature performance, processability, and crosslinkability.

TUFTEC™ P Series

Achieve Superior Crosslinkability
with Selective Hydrogenation Technology

The TUFTEC™ P series is a special type of styrene-based thermoplastic elastomer (SBBS) with selective hydrogenation using Asahi Kasei’s proprietary technology. Compared to non-hydrogenated SBS, it offers superior thermal stability, while compared to fully hydrogenated H series, it exhibits excellent low-temperature performance, processability, and crosslinkability.

Details of the TUFTEC™ P Series

Selective Hydrogenation Delivers Exceptional Impact Resistance and High Rebound Resilience

The TUFTEC™ P series is a styrene-based thermoplastic elastomer (SBBS) with partially hydrogenated butadiene-derived flexible blocks, making it a unique grade developed by Asahi Kasei. Compared to non-hydrogenated types, SBBS offers superior thermal stability. Meanwhile, compared to fully hydrogenated H series, it is characterized by higher low-temperature performance, processability, and crosslinkability. These exceptional properties make the TUFTEC™ P series suitable for various products demanding improved impact resistance and rebound resilience.
