Expanded PTFE gasket tape is a multi-purpose gasket manufactured from 100% expanded fluorocarbon material, supplied as a continuous low density tape with a self-adhesive backing strip. It is soft and spongy, permitting it to conform easily to all surface irregularities and to compress to a thin ribbon under pressure.
It is recommended as a gasket tape in steel, glass lined PVC and fiber glass pipe flanges, fume ducts, concrete lids, heat exchangers, fiberglass reinforced plastic vessels, pump housing flanges, compressor housing flanges, steam vessel flanges, manhole and manhole covers, ceramic joint, ventilation ducts, hydraulic and pneumatic systems, water systems and turbine cases.
It is an inert material which can be used in many applications against corrosive environments, except molten alkali and elemental fluorine. It will not contaminate media and can be used in food and frug equipment applications.
