The main function of this product is to ensure watertightness
PTFE offers excellent chemical resistance, pH0-14 (except for molten alkali metals and elemental fluorine), to oils, petrol, water, acids, etc
Flat gaskets made of expanded PTFE meet the food regulation CFR 21 FDA177.2600 and the EC 1935/2004 regulation. They also comply with REACH. They can therefore be used in food and pharmaceutical environments
Expanded PTFE is a soft and flexible material that adapts easily to irregular surfaces. It is ideal for use in sealing flanges that are damaged or have irregularities
Expanded PTFE has excellent pressure resistance
Expanded PTFE tolerates temperatures ranging from -240 and +260ºC with peaks up to 315ºC
El material es muy suave, por lo que su uso se recomienda en bridas con riesgo de rotura a la presión por su fragilidad (cristal, cerámica)
Quality control of expanded PTFE flat gaskets
Thanks to these characteristics, flat gaskets made of expanded PTFE can be used for:
Permit the sealing of flanges used for oils, petrol, water, acids, etc
Enable sealing of smooth surfaces
Enable operation in heat exchange systems
Enable sealing of tanks
To allow sealing between flanges which are at risk of breaking due to brittleness and pressure
