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.
