About TEFLON®

Today’s TEFLON® surface protectors are designed to provide superior resistance to stains, moisture, and organic debris such as mold, mildew, leaves, and tree resin. TEFLON® was originally used in cookware to provide a durable, nonstick surface, under high heat conditions, and has been field proven for over 50 years. The TEFLON® surface protector, now embedded in the Alunar® coating process evolved from this. Telfon® is manufactured by DuPont, a global provider of science and technology products with annual revenues of 30 billion ($U.S). For more information please visit www.dupont.com.
