Description Expanded PTFE joint Sealant is a
multi-purpose gasket tape manufactured from 100%
expanded PTFE 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.
Application Expanded PTFE joint Sealant is recommended
as a gasket tape in steel, glass-lined, PVC and fiberglass pipe flanges,
fume ducts, concrete lids, heat exchangers, fiber glass reinforced plastic
vessels, pump housing flanges, steam vessel flanges, manhole and manhole
covers, ceramic joints, ventilation ducts, hydraulic and pneumatic systems,
water supply systems and turbine cases.
Chemical Resistance Because
Expanded PTFE joint Sealant
is manufactured from 100% PTFE, it is an inert material which can be used
in many applications against corrosive environments, except molten alkali
metals and elemental fluorine. 24B will not contaminate media and can be
used in food and drug equipment applications.
