White Color Pure PTFE Expanded Tape Regular Size 1.5～7 * 3～70 * Kg
Or Meten As Request
PTFE Expanded tape is an inorganic sealant for static applications
made of 100%PTFE().
A unique process converts PTFE to a micro-porous fibrous structure,
resulting a sealant with an unsurpassed combination of mechanical
and chemical properties. It is supplied with a self-adhesive strip
for easy fitting.
PTFE Expanded tape is especially suited for sealing flange
connections, pipe system, hydraulic and pneumatic systems, etc. In
addition, it’s also ideal for seals in glass, enamel and plastic
flanges, vessels and special shaped sealing surface.
FEATURE
1 . Durable in use.
2 . excellent corrosion resistance
3 . aging resistance
4 . excellent corrosion resistance
5 . self-lubricating
6 . good flexibility
7 . high and low temperature resistance
8 . Sealing strip coated with back glue, easy to use.
9 . used in wide temperature range of long-term safety;
10 . fully fill irregular sealing surface, reduce the sealing
surface of machining accuracy,make some
broken parts and equipment due to sealing surface corrosion,
erosion and wear back to life;
Effective remedy defects, less maintenance time.Make full use of
every centimeter, no waste, more economic value,is ideally material
to replace varieties of spacer by asbestos and rubber spacers.
ADVANTAGE
PTFE Expanded tape saves money and time. Since there is no scrap or
waste, it costs less than other gasket materials. By using only a
few sizes, large inventories of sheet gasket and costly precut
gaskets can be eliminated. Installation time is kept to a minimum
since there are no templates, precutting or special fitting
requirements
