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 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 ..

What makes Expanded PTFE Sheets suitable for high pH environments?
The Expanded PTFE Sheets exhibit exceptional resistance across a broad pH range of 0-14. This characteristic allows them to effectively handle a vast array of chemicals, making them ideal for applications in various industries, including chemical processing and pharmaceuticals. However, it is important to note that they are not suitable for use with molten alkali metals or elemental fluorine.
How do Expanded PTFE Sheets compare to rigid PTFE in terms of compression and flexibility?
Unlike rigid PTFE, Expanded PTFE Sheets are softer and demonstrate superior compression capabilities. This flexibility allows them to form effective seals and gaskets, adapting to irregular surfaces and providing enhanced sealing properties. This makes them particularly advantageous in applications where a reliable seal is critical.
Can Expanded PTFE Sheets be customized with fillers, and what are the benefits?
Yes, Expanded PTFE Sheets can be manufactured with or without fillers based on specific requirements. Utilizing fillers can enhance certain properties such as tensile strength and thermal stability, making these sheets even more versatile for specialized applications.
