|SONFLON 7830 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. SONFLON 7830 is produced from virgin PTFE resin filled with Silica
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.
SONFLON 7830 is quick and simple to install. The used gasket can be removed easily and without residue.
Temperature: -210ºC to +260ºC
Pressure: 83 bar
Chemical resistance: chemically inert against all substances (pH 0-14), including the most aggressive acids and moderate lyes. It is not suitable for molten alkali metals and elemental fluorine at high temperatures and pressures.
P x T max.: 12,000 (bar x °C) based on 1.5 mm sheet thickness; 8,600 (bar x °C) based on 3.0 mm sheet thickness
Safety: SONFLON 7830 complies to FDA requirements for food, is physiologically harmless and is suitable for oxygen applications
