GLS™ TPE
AUTOMOTIVE SOLUTIONS
ENABLE LONG-TERM
PERFORMANCE
WITH TPEs FOR
FASTENERS AND CLIPS
The average length of vehicle ownership is on the rise, placing greater demands on all elastomeric materials
to maintain long-term sealing performance in fasteners and clips.
OnFlex™ TPEs provide a tight seal over these
lengthier time frames—even at elevated temperatures—and reduce vibration and noise.

HOW GLS TPEs MAKE THE DIFFERENCE IN AUTOMOTIVE FASTENERS AND CLIPS
• Low compression set – coupled with good
stress relaxation, our automotive TPEs are
designed to maintain a good seal over time and
reduce noise generated by vibration
• High temperature performance – Avient
automotive TPEs provide good sealing
performance in temperatures up to
100°C/212°F
• Bonding performance - strong chemical bond
to polypropylene, polyethylene,
and polyamide
• Process flexibility - grades can be both
injection molded and extruded
• Easy to color - can be colored at the machine
• Reduced production steps - some grades do
not require pre-drying
• Low VOC/FOG - OnFlex HT™ has been externally
tested to VDA 278 and is proven to help satisfy
vehicle interior air quality (VIAQ) regulatory
requirements
• Single source supply – we can streamline your
supply chain with the ability to provide polymer
colorants, engineered thermoplastics, and
thermoplastic elastomers from a single source
• Global support - we provide production,
technical, and commercial support in locations
convenient to your operations, including North
America, Europe, and Asia
