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 moulded)
PTFE sheets. TEALON TF1570 is produced from virgin PTFE resin filled with
hollow glass micro spheres.
Applications:
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.
