Product designers and manufacturers increasingly rely on thermoplastic elastomer (TPE) material solutions to produce and deliver highly durable and high-quality soft touch parts. Compared to the thermoplastic polyurethane (TPU) materials traditionally used for soft-touch manufacturing, TPEs offer better resistance to warpage and fatigue, as well as better protection against UV, chemical, and oil exposure.}
