In common with all grades in the Tuftec™
P series, Tuftec™ P1000 is a new polymer type,
termed SBBS, produced by selective hydrogenation at
appropriate locations on the molecular chain of styrenic
thermoplastic elastomer (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 SEBS polymers.
Tuftec™ P1000 is designed particularly for low-viscosity
hot-melt adhesives, with good flow properties and
a high-level balance in properties. It is supplied
in pellet form.

| Applications |
|
Primarily for low-viscosity hot-melt
adhesives. Superior to SBS in thermal stability. Reduced
visicosity variance and discoloration. Compatible with
full range of tackifiers, enabling broader range and
freedom in selection of co-components and formulations
than SBS or SEBS.
