PTFE sheet virgin has excellent non-stick properties and is widely used in a variety of low load applications. It is resistant to temperatures in excess of 200 deg C, has a low co efficient of friction and excellent chemical resistance. It complies with FDA requirements making it suitable for the food industry.

APPLICATIONS
Virgin PTFE (unfilled) is most often used where mechanical properties are not the most important requirement.
Our most recent projects where Virgin PTFE has been specified include high voltage electrical connectors, environmental seals within commercial fishing reels and another where Virgin PTFE was specified as a diaphragm material, bonded to an elastomer substrate to offer the best of chemical resistance and purity on one side combined with flexural properties of the elastomer.
