SIGRAFLEX® HOCHDRUCK mechnical gasket

SIGRAFLEX® HOCHDRUCK is a multilayer high-strength graphite sealing sheet comprising 0.5 mm thick layers of high-purity graphite foil and 0.05 mm thick stainless steel foils.

Depending on the sheet thickness required, several layers of graphite and stainless steel foil are joined together in a patented adhesive-free process. As a result, the sheets have outstanding mechanical properties. The sealing sheet is impregnated to reduce leakage and improve handling.

SIGRAFLEX® HOCHDRUCK allows end users in the process industry to cover almost their entire gasket application range with a reliable and safe product.
