Tealon TF-1570
TEALON TF1570 is a structured PTFE - Gasket - Sheet manufactured by a uniqueprocess which provides a high level of fibrillation to overcome the creep relaxation and cold flow problems associated with normal (skived or molded) PTFE sheets.
This style is produced from virgin PTFE resin filled with hollow glass micro spheres.
APPLICATION / SERVICE
TEALON TF1570 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 this style makes it particularly suitable for use with stress sensitive and/or fragile flanged joints, e.g. glass, ceramics, plastic, etc.
AVAILABILITY
TEALON TF1570 is available in sheets of 59” x 59” (1500mm x 1500mm) with a thickness of 1/16” or 1/8”.
