reSound™ REC Recycled Content TPEs
Sustainable TPEs for automotive interiors
The demands for improved sustainability continue
to drive innovation and change across the
transportation industry.
Developed in response
to the increased need for sustainable material
alternatives, reSound™ REC TPEs provide
comparable performance to traditional fossil-based
grades, and support goals for reduced waste and
carbon emissions.
Designed to meet common OEM requirements, these
recycled grades offer similar aesthetics to prime
TPEs.

Overmolding TPE compounds have a relatively low viscosity.
ADHESION MEASUREMENT OF THE OVERMOLD TPE
The bond strength between the TPE and the engineering plastic can be measured by performing a “90° Peel
Test”.
NOVEL TPE DEVELOPMENTS:
Non-Drying TPEs for PC, ABS, PBT and their alloys
Novel classes of non-drying TPEs which can overmold onto a variety of engineering thermoplastics have been
developed.
