GLS™ TPEs - Injection Molding Guide GLS™ TPEs - Overmolding Guide Thermoplastic Elastomers: GLS™

The Avient team assessed the application’s technical and operational requirements, and recommended GLS Versalloy™ XL- 9045-1 alloy in 45 Shore A durometer, an FDA-compliant medical TPV grade designed for overmolding onto PP. THE IMPACT Avient’s expertise in materials for medical device applications helped this customer make a smooth transition to the GLS TPV.

To meet the manufacturer’s goals for the mouse grip, a clear TPE overmolding material, GLS Versaflex™, was formulated for improved ergonomics and comfort, strong chemical resistance, and excellent bonding to the ABS substrate. A technical support team at Avient GLS Thermoplastic Elastomers conducted extensive compatibility testing to confirm proper bonding and overmolding onto the rigid substrate.

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. KEY CHARACTERISTICS • Protects finished part by inhibiting microbial and fungi growth • Extends useful life of finished TPE parts by controlling deterioration caused by mildew or mold fungus • Increases product durability, preserves surface integrity, and minimizes odors MARKETS & APPLICATIONS Suitable for high-touch surfaces and applications, GLS TPEs with antimicrobial technologies add value in the consumer, packaging and automotive markets.

Generally, GLS TPEs will flow much further in thinner walls than other types of TPEs. High flow GLS TPEs (such as Versalloy) have been used successfully to fill flow ratios up to 400. Typical spiral flow lengths for GLS TPEs*

One of the key properties of thermoplastic elastomers supplied by GLS is hardness. Processing Styrenic Block Copolymer TPEs from GLS GLS produces standard products ranging in hardness from 3 Shore A (softest) to 95 Shore A (hardest). 

One of the key properties of thermoplastic elastomers supplied by Avient GLS is hardness. GLS Grade GLS typically reports hardness using the 10 second delay method.
