โฆ Synopsis
This covers a gasket similar to that described in WO/2009/060689. In this case the sheath is described as PTFE or inorganic sheets that are laminated and bonded to the thin metal plate of core material. It is, again, claimed to work with both low and high compression forces. Large deformation of the sheet is controlled and thinner PTFE sheets (12, 13) or inorganic sheets can be used by preventing the low fluidity PTFE sheet or inorganic sheet from being broken even if a high fastening load is applied.
