In addition to the lighter weight requirement, the
material and process would need to deliver an ultra-low
cycle time with improved processability and tailored
crystallization dynamics, while also resisting warpage
after molding, a common issue for thin walled plastic
parts.

Since PEI resin offers excellent resistance to
heat and fire, and has very good dimensional
stability, it is ideal for a variety of applications
in industries such as aerospace, automotive,
telecommunications and healthcare.

GLS™ TPEs with Antimicrobial Technologies
This specialty line of GLS™ thermoplastic elastomers
has imbedded antimicrobial additives that inhibit
bacterial growth by 99.9% or more (log 3) and resist
fungal growth to protect molded plastic parts.

They also add important characteristics, such as
SWELLCOAT® water-blocking, water repellence, adhe-
sion, color, and wear and UV-resistance to these and
many other applications.

On one hand, soft materials can reduce shoulder
impact, but it’s tough to find a material that provides
plenty of comfort while also resisting material
breakdown.

In response to the tests, Avient leveraged
its expansive portfolio of specialty additives to tailor
the TPE for enhanced UV resistance and to inhibit mold
growth—leading to an end product that would perform
better for longer.
