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. For the mouse feet, Avient formulated a special grade of LubriOne™ filled acetal as an improvement over the neat acetal found in traditional designs.
