(Ù TEADIT NA1500 Virgin PTFE Sheet DESCRIPTION / APPLICATION Style NA1500 PTFE (polytetrafluoroethylene) is a high molecular weight polymerand one of the most versatile plastics known to man. Style 1500 virgin PTFE sheet can handle virtually ail chemicals in the 0-14 pH range wîth the exception of molten alkali metals and elemental fluorine. It is suitable for service at températures from the cryogénie range up to 500°F. This style is particularly recommended for applications in the food and beverage industry where high purity materials are required. It is also used where contamination or discoloration of flow média cannot be tolerated.
