Abstract
A shaft-sealing sliding member which is formed by thermal compression molding by using the mixture consisting of graphite component powder, synthetic resin binder and boron nitride powder. The shaft-sealing sliding member is excellent in several properties such as self-lubricating property and wear resistance. In order to improve these characteristic properties, if necessary, one member or both of silicon dioxide and silicate may be added to the above mixed material.
