What are the properties of PTFE?
PTFE (Polytetrafluoroethylene) is versatile due to its chemical resistance and temperature resistance from -100 °C to 250 °C. It is resistant to almost all media, except for highly alkaline metals and fluorine under high pressure. PTFE gaskets are particularly suitable for applications that require high standards of resistance and purity.
