To make its punched gaskets, CMD uses SGL Carbon expanded graphite sheets, among the best in the world in terms of purity, density and compressibility.

The raw material used for their production, consists of natural graphite flakes, having a well-ordered crystal structure, which are then transformed into the graphite we know. These pure graphite composites are compressed, without the addition of adhesives or fillers, forming sheets of raw material with exceptional strength and behavior properties.

Stamped graphite seals are optimal for static seals in low, high and very high temperature applications. They have excellent resistance to chemicals.

Nonetheless, they are produced very smoothly with dies created to perfectly reproduce the customer’s design.

CMD also offers a range of sheared PTFE gaskets, which, subject to identical accuracy in fabrication, perform their function where mechanical performance and temperatures are lower.
