The Teflon Surface Protectors of today are only distant cousins of the original Teflon fluoropolymer discovered by the DuPont Chemical Co. over 50 years ago.
That original Teflon coating — still used worldwide to give pots, pans and other cookware a durable, nonstick surface — later evolved into a new family of fluorochemicals designed to prevent stains in carpets, and is marketed under the Stainmaster® tradename.
