Abstract:
A gasket material including: a metal plate; and a fluorine rubber layer having a Vickers hardness of 15 to 30 N/mm2, being provided on one side or both sides of the metal plate, and obtained from a fluorine rubber composition containing a fluorine rubber polymer. The gasket material maintains a sealing bead surface at a high surface pressure without changing the engine block design and the gasket design and also possible to absorb flange surface roughness that is an original purpose of the rubber layer.
