Sealing technology with graphite seals and sealing materials

Contact 0

To prevent unwanted emissions resulting, for example, from gas or liquid leakage, a secure sealing of production plants, aggregates and machines is a key issue in almost all industries. In many cases, gaskets made of graphite offer significant added value, whether in the chemical and petrochemical industry or in refineries with their corrosive and toxic media and high process temperatures, in the automotive industry, in mechanical engineering, in the pulp and paper industry or even in power plants.

With its know-how along the entire value chain, from the selection of raw materials to the production of graphite materials and technical service, SGL Carbon offers specialty graphite solutions for both static and dynamic sealing applications.

For 50 years, our SIGRAFLEX flexible graphite materials and our SIGRAFLEX carbon and graphite yarns have and continue to deliver the ultimate sealing solution: Supporting our customers in making the difference – no matter if the graphite sealing materials are used to produce flat, spiral wound, corrugated or Kammprofile gaskets, die-formed or braided packing rings.
