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

Concentrated Acid - 30% H2SO4, 24 HRS, 23°C
Nylon samples were almost completely dissolved after one day, while the Edgetek PKE bars are still visible.
Gasoline - 30% glass-filled (GF) grade, dry as molded (DAM), room temperature
Testing methodology is an adaptation from ASTM D543
• Reapply freshly soaked gauze pad every 24 hours to prevent from drying out
• Repeat for a total of 72 hours
• Tensile properties recorded
