What is ePTFE Joint Sealant Tape?
ePTFE
joint sealant tape is a very versatile gasket tape. These soft gasket
tapes are highly compressible, allowing them to offer sealing along
surfaces with even minor gaps and crevices.
Our ePTFE
joint sealant tape come with a one-side adhesive backing and are
available in all standard cross sections. Custom dimensions are also
available on request. ePTFE joint sealant tape offers excellent chemical
resistance, withstand high temperatures, and can provide sealing in
pressures of up to 100 bar.
Advantages and Benefits
ePTFE
joint sealant tape has 60% compressibility with 14% recovery that make
it have superior sealing even at minimum torque loads, it has one side
adhesive so it is easy ti be installed and fixed. It has high chemical
resistance, High endurance even in extremely corrosive environments.
Application
ePTFE
joint sealant tape is safely used in applications on oil rigs, petroleum
refineries, offshore operations, corrosive chemical processing, food
processing, paper mill, marine installation, in glass lined or fibre
glass reinforced vessels and tank lid sealing, heat exchangers, manhole
covers, vent pipes, pumps or compressors housing flanges, valves and
many other industrial applications where the use of a conventional
pre-cut gaskets is not suitable or readily available.
Differences between PTFE and expanded PTFE
You are probably wondering what the differences are between conventional PTFE and expanded PTFE.
Both
materials share similar properties that are optimal for industrial
applications. However, expanded PTFE has a superior versatility than
PTFE and, consequently, it can be manufactured in different sizes,
densities and thicknesses.
Key Features
Temperature: -200°C to +280°C (+315°C short term).
Max Pressure: 210 Bar.
