For many GLS overmolding grades, the use of a polyethylene (PE) carrier may adversely affect adhesion.
It is common practice to use two mold temperature controllers while running GLS materials.
The adhesion of GLS soft overmolding TPEs to a substrate may be affected by:

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

The Avient team assessed the application’s technical and operational requirements, and recommended a GLS™ Versalloy™ alloy in 45 Shore A durometer, an FDA-compliant medical TPV grade designed for overmolding onto PP.
Ultimately, the transition to the GLS TPV proved to be a smooth one for the manufacturer.
