Molding Soft TPEs (≤ 20 Shore A) Soft GLS TPEs have very low viscosity (high flow); thus they require minimal injection pressure.

Properly designed deep undercuts are possible with GLS overmold TPEs. Spiral flow testing results for GLS products are presented below using injection speeds of 3 in/sec and 5 in/sec. 30-32

There are several GLS products in the 40 Shore A Hardness range that have varying COFs. There are several GLS™ products in the 40 Shore A Hardness range that have varying COFs. For GLS materials with hardnesses over 50-90 Shore A, a sprue puller with a Z-type may be used to pull the sprue out.

Available in two Shore A hardnesses, Versaflex HC grades can also be customized to achieve desired haptic qualities. With a Shore A hardness of 48, Versaflex HC 1348 is slightly softer than Versaflex HC 1365, which has a durometer of 65A and a matte finish.   Media contact Sandy Wagner Marketing Communications Manager PolyOne GLS Thermoplastic Elastomers +1 815-759-2676 sandy.wagner@avient.com

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.

With its 40 Shore A hardness, it also offers a low compression set to protect sensitive audio components from water and dust. The second grade, with 80 Shore A hardness, enhances speaker skin design with a silky feel, excellent colorability and outstanding resistance to abrasion and environmental effects.   The popularity of wireless speakers has exploded, giving smartphone and tablet users the freedom to listen to and share music anywhere they choose,” said Michelle Hearn, global marketing director, GLS™ Thermoplastic Elastomers at PolyOne.
