Information

Gasket DN50 PN40 PTFE Graphite combines the outstanding chemical resistance of PTFE with the enhanced mechanical strength provided by 15% graphite. The graphite filler improves hardness, wear resistance, and durability, making the gasket ideal for demanding industrial applications involving high loads and elevated temperatures.

In addition to its widespread use in the chemical and food processing industries, PTFE is also valued for its excellent electrical insulation properties.

PTFE is resistant to almost all solvents, with fluorine and certain fluorine compounds being among the few exceptions.
