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.

– PolyOne GLS Thermoplastic Elastomers today announced the launch of an overmolding technology based on Versaflex™ VDT thermoplastic elastomer (TPEs), developed for vibration and impact damping applications. Customers familiar with our Versaflex VDT material have asked for an overmolding variation that allows them to leverage the design freedom of two-shot and insert injection molding,” said Charles Page, director, global marketing, PolyOne GLS Thermoplastic Elastomers. Additionally, the PolyOne GLS material is more cost-effective than self-adhesive vibration damping tapes and avoids secondary operations.  

GLS believes these factors all play a role in the decision process and should be used in your decision process. For example, using GLS product XL9070 (SpGr of 0.89) and GLS product G7970 (SpGr of 1.18), both 70A TPEs, the mass of the part in grams is calculated as follows:

HOW GLS TPES MAKE THE DIFFERENCE IN INFANT CARE APPLICATIONS • Safe to Use – Made without bisphenol A (BPA), phthalates, or heavy metals; select grades compliant with FDA, REACH and China GB4806 • Durable – Resists bites and tears; many are tested and safe to use in microwaves and dishwashers • Comfortable – Can be overmolded to provide a soft touch grip and customized to specific comfort requirements including vibration and noise reduction • Easy to Process – Can be injection molded and overmolded right onto a substrate including PP, ABS, etc Better Quality Control – Eliminate the need for many secondary operations required for other materials so that results are controlled and consistent To learn more about GLS TPEs for infant care, contact Avient at +1.844.4AVIENT. Our GLS TPEs safely deliver on all of these requirements, while also adding comfort and enhancing consumer appeal.
