TEALON TF1580 Structured PTFE Gasket Sheet

TEALON TF1580
Structured PTFE
Gasket Sheet

DESCRIPTION
Tealon TF1580 is a structured PTFE Gasket Sheet manufactured by a unique process which provides a high fibrillation level to overcome the creep relaxation and cold flow problem associated with skived PTFE sheets. Tealon TF 1580 is produced with virgin PTFE resin filled with Barium Sulfate.

APPLICATION / SERVICE
It is suitable for services with general service in wide variety of fluids, strong caustics, moderate acids, chlorine, gases, water, steam, hydrocarbons, hydrogen and aluminum flouride.

AVAILABILITY
Is supplied in off-white color, in sheets of 59" (1500mm) x 59" (1500mm). Thickness : 1.5 to 3.0mm.
