CASE STUDY: BERGAMID™ POLYMER FORMULATIONS & GLS™ TPES
Challe
nge Accepted.
Avient material scientists found the perfect combination
with a custom rigid nylon formulation for the handle
paired with a soft GLS™ thermoplastic elastomer (TPE)
in the grip areas.
Beyond finding the
best material combination—Bergamid™ nylon copolymer
and GLS™ TPEs—our global presence and expertise
across an array of specialty polymers and colorants,
combined with local service and support, helped
Victorinox to accelerate development work, streamline
production and reach their design goals.

Known for offering tight seals and reducing
vibration and noise, certain thermoplastic elastomers
(TPEs), like OnFlex™ grades, may be better suited
for your particular application than the historically
incumbent materials, like general purpose TPEs,
thermoplastic vulcanizates (TPV), and thermoplastic
polyolefins (TPO).
