novaphit® MST
novaphit® MST is a material of thermally expanded graphite in the form of a sandwich, consisting of layers of thermally expanded graphite (up to eight layers), expanded metal and sheet steel (up to seven layers). Thanks to the multi-layer construction from a combination of graphite foil and smooth metal inserts, this material achieves the highest thermal and mechanical properties as well as the lowest leak rates. The increased strength characteristics allow novaphit® MST to be used as a replacement for spiral wound gaskets. Possesses high pressure resistance, excellent adaptability in the flange and versatility of use, perfectly withstands dynamic loads.
