TEALON TF1570 Structured PTFE Gasket Sheet

TEALON TF1570
Structured PTFE
Gasket Sheet

DESCRIPTION
TEALON TF1570 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 molded) PTFE sheets. TEALON TF1570 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 TF1570 makes it particularly suitable for use with stress sensitive and/or fragile flanged joints, e.g. glass, ceramics, plastic, etc.
