HOW GLS TPEs MAKE THE DIFFERENCE IN AUTOMOTIVE HVAC APPLICATIONS
• Low VOC/FOG – externally tested to VDA 278
and shows significant reductions in volatile
organic compounds and fogging when
compared to current TPE technologies
• Industry standards – helps to achieve VOC/
FOG performance standards for improved VIAQ
• Reduced manufacturing steps – does not
require pre-drying or post heating to reduce
VOC in parts produced
• Design optimization – color can be added at
the machine
• Easy to process – can be extruded, injection
molded and extrusion blow molded
• Recyclable – Our automotive TPEs are
compatible with most municipal recycle
streams
• Global support – Avient automotive TPEs
can be manufactured in locations that are
convenient to your operations, including
North America, Europe or China

Using phase barriers made of Avient’s OnFlex™ S HF, HF 7001, and Synprene or Synprene™ RT
thermoplastic elastomers (TPEs) will help you deliver on that promise.
RoHS compliant – Avient OnFlex S HF, HF 7001,
and Synprene or Synprene RT comply with all
relevant regulations including RoHS, and specific
grades qualify as UL 94 V-0.
In addition, OnFlex S HF,
HF 7001, and Synprene or Synprene RT complies
with REACH SVHC.

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
