Graphite Gasketing Sheet

Composition

High-purity expanded mineral graphite Industrial Grade with tanged or smooth SS316L sheet if required by the style.

Characteristics

The expanded mineral graphite Planigraph™ meets the requirements of the latest update of the EU directive 2011/65/EC (RoHS). This type of gasket ensures a reliable and durable sealing, making it an ideal option for all industrial applications, from the simplest to the most demanding.

Applications

Expanded mineral graphite is also known for its chemical resistance, making it suitable for applications involving almost all fluids except for oxidants. In addition, expanded mineral graphite gaskets can be easily cut and shaped to fit the specific needs of the application. Thanks to its high thermal resistance, expanded mineral graphite can withstand high temperatures without damage or deformation, ensuring a reliable and safe sealing.
