PTFE, or polytetrafluoroethylene, is a TeflonÂ®-coated woven fiberglass membrane that is extremely durable and weather resistant. PTFE fiberglass membranes can be installed in climates ranging from the frigid arctic to the scorching desert heat with a project life in some cases exceeding 30 years.PTFE fiberglass coating is chemically inert, capable of withstanding temperatures from -100Â°F to +450Â°F (-73Â°C to +232Â°C).TFE fiberglass membranes can be installed in climates ranging from the frigid arctic to the scorching desert heat with a project life in some cases exceeding 30 years.

Teflon Â® is a brand name for a man-made chemical known as polytetrafluoroethylene (PTFE). It has been in commercial use since the 1940s. It has a wide variety of applications because it is extremely stable (it doesn't react with other chemicals) and can provide an almost frictionless surface.ost people are familiar with it as a non-stick coating surface for pans and other cookware. It is also used in many other products, such as fabric protectors. Perfluorooctanoic acid (PFOA), also known as C8, is another man-made chemical.
