The adhesion is categorized based on
adhesive failure (A)- if no TPE residue is left on the substrate, or cohesive failure
(C)- if the failure is in TPE.
Design Considerations
The material requirements of bondable TPE’s are different from conventional
TPE’s and it is the same for designing parts.
Prevent the TPE from flashing over areas on the substrate.

The automated
pultrusion process fabricates continuous glass or carbon
fiber-reinforced, constant cross-section profiles with
consistent, uniform properties.
Each cradle brace is a two-foot long, rectangular bar
with a “U” shape machined into our engineering team
developed and analyzed three options: a unidirectional,
hybrid carbon and glass fiber profile; a unidirectional
carbon fiber profile; and finally, a profile made with both
a unidirectional carbon fiber and a transverse engineered
fabric, which had the advantage of minimizing any
potential cracks from propagating.
The third profile was also 41% lighter
than aluminum, with a 50% increase in flexural stiffness,
and maintained torsional rigidity slightly better than that
of aluminum.

This includes lower-carbon alternatives to thermoplastic elastomers (TPEs) without sacrificing performance, portfolio expansions including bio-renewable feedstock and post-industrial or post-consumer recycled (PCR) content, and new materials and services focused on meeting specific customer needs while helping to advance a circular economy.
reSound™ Ultra-Low Carbon Footprint TPEs: These TPE formulations offer an industry-first cradle-to-gate negative, neutral, or near-zero product carbon footprint (PCF) while delivering comparable performance to traditional TPEs.
Once completed, the site will host a fully functional physical testing lab, a sophisticated analytical lab, a wet chemistry facility, and dedicated process capabilities, including multi-scale twin-screw extruders, reactive extrusion, and various injection molding machines.

VERSAFLEX™ CE TPEs FOR 5G TRANSPARENCY
Rapidly expanding 5G networks are increasing
performance requirements across the consumer
electronics industry.
These 5G transparent
TPEs combine the excellent physical properties,
aesthetics and UV resistance qualities of traditional
TPEs with lower dielectric constant (Dk) and
dissipation factor (Df) performance, resulting in
an advanced material solution with less signal
degradation for next-generation devices.
