The tub features a custom overmolded GLS Versaflex™ thermoplastic elastomer (TPE) and non-toxic PolyOne OnColor™ colorants. In addition, Karibu chose PolyOne’s non-toxic OnColor™ colorants, which are customizable and compatible with the GLS TPE material.   Karibu selected our TPE and colorants because they are superior to conventional products,” said Michelle Hearn, director of marketing for PolyOne GLS.

– 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.

For many GLS overmolding grades, the use of a polyethylene (PE) carrier may adversely affect adhesion. It is common practice to use two mold temperature controllers while running GLS materials. The adhesion of GLS soft overmolding TPEs to a substrate may be affected by:
