When a TPE has to be both very tough and “window clear,” Elastocon TPE Technologies,
Rochester, Ill., recommends its new CLR Series. They are completely oil-free and odorless and come in 65A and 75A durometers. They can be injection molded or extruded and reportedly offer exceptional tear resistance, shiny surfaces, and very high flow. They utilize ingredients that are FDA-compliant and can easily be color-tinted.
