Tuftec™
P2000
SBBS: Selectively hydrogenated styrenic thermoplastic
elastomer |
|
| Essentials |
In common with all grades in the Tuftec™
P series, Tuftec™ P2000 is a new polymer type,
termed SBBS, produced by selective hydrogenation at
appropriate locations on the molecular chains of styrenic
thermoplastic elastomers (styrene/butadiene/styrene;
SBS). As a result, it is inherently outstanding in
thermal properties, and superior in processability
and low-temperature properties to the structurally
similar Tuftec™ H series of SEBS polymers.
Tuftec™ P2000 is high in styrene content, and
particularly effective as a modifier for styrenic,
polyphenylene ether (PPE), and other polymers, and
as a compatibilizer for styrenic and olefinic polymers.
It is supplied in pellet form.
