Abstract

PURPOSE: To obtain a gasket excellent in the sealing function with a proper resistance to high temperature and high pressure through solid lamination of the circular core material by employing a thermosetting resin in such a manner that a glass cloth impregnated with the resin is piled together with a cushion material.
CONSTITUTION: A PTFE-wrapped gasket 1 is composed of a PTFE ring body 2 and a circular core material 3. The ring body 2 is made thin with a circular groove 4 on the circumference thereof. On the other hand, the circular core material 3 is made up of a cushion material 5 which is constructed of fiber material having a heat resistance, such as felt and mat and a glass cloth 7 impregnated with a thermosetting resin 6 left unhardened. These two materials are alternately piled one upon another, integrated by heating and properly cut through in a circular manner. After the circular core material is inserted into a circular groove 4 of the ring body 2, the body is pressurized from both sides to straighten shrinkles. The ring body 2 bites into the rough surface of the glass cloth thereby checking the infiltration of flow.
