TEALON TF1590 Structured PTFE Gasket Sheet

TEALON TF1590
Structured PTFE
Gasket Sheet

DESCRIPTION
Tealon TF1590 is a restructured 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 1590 is produced with virgin PTFE resin filled with Silica.

APPLICATION / SERVICE
It is suitable for services with high pressures and temperature, especially in chemical processing and hydrocarbon plants in strong acids (except hydrofluoric), solvents, hydrocarbons, water, steam, and chlorine.

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

> pH Range : 0 - 14
> Max Pressure : 1200 psig (83 bar)
> Temperature : -350ºF (-210ºC) to +500ºF (+260ºC)
> P x T max.* : 350,000 (12,000)** and 250,000 (8,600)***
