Essentials
Tuftec™ is a hydrogenated styrene/butadiene
block copolymer. As a high-performance styrenic thermoplastic
elastomer (TPE), it is characterized by outstanding
weatherability and thermal properties, as well as superior
elastomeric characteristics.
It is a product of continuing leadership in polymer
chemistry and process technology, marked by the original
introduction of the Tuftec™ H series in 1987 as
the world’s second saturated styrenic TPE to enter
commercial production, preceded only by Shell Chemical
of the U.S., by the introduction of the Tuftec™
M series as the world’s first reactive TPE, and
most recently by the introduction of Tuftec™ P,
the latest series in an array of world-leading TPEs.
The new Tuftec™ P series meets advanced and diversifying
market needs. Through site-selective hydrogenation of
its styrene/butadiene/styrene (SBS) polymer chain, the
P series elastomers are intrinsically superior to conventional
SBS in thermal properties and to saturataed styrenic
elastomers (SEBS) in processability and low-temperature
properties. This selective hydrogenation technology
also enables polymer design for enhanced overall performance
and specific characteristics unattainable in other syrenic
elastomers.
- In adhesive applications, Tuftec™
P1000
is compatible with a many kinds of tackifiers,
including those that can not be used with conventional
SBS and SEBS, thus bringing a new level of flexibility
and efficiency to the design and utilization
of adhesive formulations.

- As a
compatibilizer for styrenic resin and olefinic
resin blends, Tuftec™ P2000
enables highly efficient dispersion and compatibilization
between polyolefins and polystyrenes, polymers
such as ABS and polyphenylene ethers.
