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. Thermoplastic Elastomers: GLS™ Versaflex™

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. Most GLS styrenic TPEs (Dynaflex and some Versaflex) have fairly high mold shrinkage and cause the overmolding TPE to contract more than the substrate, which can result in warpage or cupping of the substrate part.

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.

Regulatory compliance for aqueous, acidic, alcohol and fatty food applications are available with GLS thermoplastic elastomers. GLS and Kautex Machines, a leader in extrusion blow-molding equipment, jointly developed a solution for co-extruding an ultra-thin outer layer of translucent, customized Dynalloy™ TPE onto recycled or virgin HDPE resin.
