Table 1 summarizes the physical properties of GLS TPS suitable for overmolding. Table 2 lists the GLS TPE products that were developed to overmold onto different substrates along with their adhesion test data. Figure 2 illustrates some common GLS Materials, their supplied hardness, and the relationship between hardness and thickness.

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.

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.

GLS TPEs can be customized for various color effects, levels of opacity and different types of feel and texture. Unlike other materials, GLS TPEs are recyclable, which is becoming increasingly more important to all consumers.
