KLINGER® Graphite Laminate PSM
The pure graphite gasket material with a stainless steel tang insert
KLINGER® Graphite Laminate PSM has a 0.1 mm thick perforated stainless steel insert. The insert aids material handling properties and also increases the blow-out resistance. The insert is mechanically bonded to pure exfoliated graphite and therefore does not rely on adhesive.
Stable physical properties over the whole temperature range. KLINGER® Graphite Laminates PSM is suitable for hot water and steam at high temperatures up to 842°F (450°C).
In order to prevent the gasket material from sticking to the flange surface (even at high temperatures), the graphite surface can be given a non-stick coating at the customer's request. With this process, the gasket material's surface is coated and not impregnated.
