PTFE Material Properties
Due to its unique molecular arrangement, PTFE has an extremely low coefficient of friction. In addition, it is non-reactive with most common gases and liquids and has excellent chemical resistance.
It can be continuously used at temperatures up to 250°C (490°F) and works well at extremely low (cryogenic) temperatures.
Reinforcing fillers, wear resistant additives and self-lubricating fillers are typically applied to enhance the properties of PTFE. Fillers are selected and combined to reduce wear and improve performance based on the specific operating environment.
