Pure PTFE tape is for making spiral wound gasket,
Expanded PTFE tape with high quality is also available for making sprial wound gasket.
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.
