Beschreibung
Zusammenfassung:	PURPOSE:To obtain a gasket material, good in water and oil resistance and excellent in sealing properties without causing oil collapse, grommet breakage, etc., by bonding expandable graphite to both sides of a reinforcing core plate consisting of heat-resistant fibers with a resin. CONSTITUTION:The objective gasket material obtained by bonding plain expandable graphite sheets having preferably 0.05-0.07mm thickness to both sides of a reinforcing core plate, consisting of heat-resistant fibers, such as glass, carbon, phenolic resin or aramid fibers, and having preferably 0.05-0.5mm thickness with a resin consisting of a thermosetting resin, such as epoxy, phenolic, furan or polyimide resin. The above-mentioned material is punched into the form of a head gasket and the peripheral part of an opening in the resultant formed body is then coated with a heat-resistant resin to produce the head gasket.
