Sigraflex Hochdruck with Inner Eyelet is a multilayer high-strength sheet material comprising 0,5mm thick layers of high-quality graphite foil (type Z) and 0,05 mm thick stainless steel foil. The inner eyelet (316TI) reinforcement on the edge significantly improves the pressure resistance of the flat seal, especially in surge pressure situations, prevents corrosion of the sealing surface and facilitates the handling of the seal. Depending on the sheet thickness required, several layers of graphite and stainless steel foil are jointed together in a special process. Due to the high purity of graphite (99.85%), Sigraflex Hochdruck is suitable for use in nuclear power plants.
