The resulting custom-formulated grades of GLS™ Dynalloy™ OBC and Versaflex™ TPE allowed the manufacturer to switch to a two-shot molding process that eliminated the time-consuming and costly assembly operations needed for the old part.
Reduced assembly costs: Switching to Dynalloy™ OBC and Versaflex™ TPE allowed the introduction of two-shot molding, which eliminated a multi-component assembly process.

Versaflex
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.
