Specification of GASKET TEALON TF - 1570
Description:
TEALON TF 1570 is a structured PTFE - Gasket - Sheet
manufactured by a unique process which provides a high level of
fibrillation to overcome the creep relaxation and cold flow
problems associated with normal (skived or moulded) PTFE
sheets. TEALON TF 1570 is produced from virgin PTFE resin
filled with hollow glass micro spheres.
Advantages:
• TEALON TF 1570 is suitable for service with a wide variety of
aggressive fluids, including hydrocarbons, acids and caustics,
solvents, water, steam, hydrogen-peroxide, refrigerants, etc.
• The high compressibility of TEALON TF 1570 makes it
particularly suitable for use with stress sensitive and/or fragile
flanged joints, e.g. glass, ceramics, plastic, etc.
• The excellent malleability of TEALON TF 1570 makes repairing
of small damages and/or irregularities of the sealing area
(flange surface) unnecessary.
• TEALON TF 1570 is quick and simple to install. The used gasket
can be removed easily and without residue.
Properties:
• Color: blue
• Size: Sheets of 1500 mm x 1500 mm
• Thickness: 0.5 mm up to 6.4 mm
• Temperature: -268 ºC to +260 ºC
• Chemical resistance: chemically inert against all substances (pH
0-14), including the most aggressive acids and lyes. It is not
recommended for strong caustic service above 80°C. It must not
be used in contact with molten alkali metals and elemental
fluorine at high temperature and pressure.
• Operating Pressure: 55 bar
• Ageing: TEALON TF 1570 is not subject to ageing or
weathering. It can be stored indefinitely.
• TEALON TF 1570 complies to FDA requirements for food, is
physiologically harmless and suitable for oxygen applications.
