Zusammenfassung: | PROBLEM TO BE SOLVED: To prevent a fretting abrasion of the surface of a gasket using a joint sheet as a raw material and improve the sealing property of the gasket widely as compared with the gasket by using the conventional joint sheet as the raw material. SOLUTION: This gasket material is characterized by applying a low frictionizing treating liquid containing a polytetrafluoroethylene on the surface1a of a joint sheet formed by a raw material obtained by mixing a rubber, reinforcing fiber and filler, while mixing/kneading, and vulcanizing to form a low frictional film 3.
