Expanded PTFE Sheets

Our high-quality Soft Expanded PTFE Sheets are made of 100% expanded biaxial PTFE (ePTFE), without fillers / or at request with fillers/, without pigments or inks. They are soft and with very good compression, compared to the rigid PTFE.

The expanded PTFE sheets have a very high pH resistance range (pH 0-14) and can handle almost every medium available -  except molten alkali metals and elemental fluorine.

The expanded PTFE in the form of sheets has excellent temperature resistance in a very wide range of temperatures - between -210 ° C to + 260 ° C, short THERM 315 ° C (recommended temperature from -200 ° C to + 230 ° C).

Moreover - the EPTFE sheets are approved by FDA an are physiologically inert in all recommended applications. 

We offer Expanded PTFE sheets in four different versions - 100% expanded PTFE or expanded PTFE with glass fillers, silica fillers or filler of barium sulphate.

Expanded PTFE Sheets

Expanded PTFE - EPTFE Gasket material is a soft and conformable material that is ideal for applications with limited bolt load torque available.  Or in applications such as glass lined pipe where excessive bolt load will cause more problems than it will solve. 

If you have never touched this exceptional sealing material think of a dense marshmallow. It has the same chemical resistance and temperature range as any PTFE but it is soft and will effect a seal much quicker than regular PTFE gasket material.

Advantages:

  • excellent tightness; full resistance; 

  • suitable to fill wide flange gaps; 

  • easy to install; 

  • easy to cut, punch and plotter; 

  • withstands high loads; very low cold-flow tendency; 

  • excellent recovery properties; suitable for changing loads; 

  • suitable for high-temperature applications; 

  • allows a precise mathematical approach to the sealing application; 

  • harmless in contact with food;
