Consider combining comfort with color and performance properties using enhanced soft touch GLS™ TPE materials for even better results. When overmolded, GLS TPEs bond permanently and virtually seamlessly to many different plastic substrates, including polypropylene (PP), polycarbonate (PC), acrylonitrile-butadiene-styrene (ABS), PC/ABS, copolyester, polyamide (nylon) and polystyrene (PS). Consumer products that use a TPE grip have been used extensively to provide ergonomic benefits, particularly for usability and safety.
