Expanded ptfe joint sealant is a white pure ptfe product with
continuous banding, it has good flexibility peculiarity,
encapsulate resilience, highresistant & low temperature
and excellent resistant corrosion, no aging, lubrication itself.
The sealed Peculiarity excellence and install it expediency.
Application:
Expanded PTFE joint tape 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: ptfe sealing tape 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.
