GLS Thermoplastic Elastomers, a PolyOne business, recently announced the issue of a patent for the universal overmolding TPE platform for polyamide (PA). The patented technology is based on the VERSAFLEX™ chemistry and delivers consistent bonding and performance with any type of PA, regardless of the supplier, chemistry or additives, using either insert or two-shot molding under a broad range of processing conditions. GLS has solved one of the perennial challenges of the TPE industry by developing the universal nylon overmolding grade that bonds to a full range of PA materials.
The patented technology will initially fulfill needs within the power tool market, where a variety of PA substrates are used. In addition, the material can provide excellent aesthetics, enhanced ergonomics, comfort, a non-slip grip, and shock absorbency. Previously, there was no single TPE that could offer reliable overmolding results with PA substrates. As per the company, TPE materials compounded with the new technology are designed to bond to a wide array of polyamide substrates, including grades reinforced with glass fiber, or those containing various additives. These materials are also said to have exceptional colorability and process easily without being sensitive to polyamide molding conditions such as humidity or to post-mold aging conditions, and can be overmolded onto PA using insert molding or two-shot molding.
