KLINGER® Graphite Laminate PDM
The more highly compressed pure graphite gasket with two rough sheet metal inserts
Basis
Glueless gasket material consisting of expanded graphite and two 0.1mm thick tanged stainless steel insert. The material is free from resins, impregnations or other organic compounds. Therefore it is free of eventual toxic risks. Stable physical properties over the whole temperature range.
Areas of application
KLINGER® Graphite Laminate PDM is suitable for high-pressure applications, hot water and steam at high temperatures up to 450°C.
Key features
- Mechanically bonded tanged stainless steel inserts
- Free of organic resins or toxic risks
- Excellent chemical resistance
- Excellent high temperature resistance
Benefits
- Stable physical properties over the whole temperature range
- Very good tightness
- Suitable for high pressure applications
