PURPOSE:To obtain a molding material having excellent moldability, heat- resistance, lubricity, abrasion resistance and sliding properties at a low cost by compounding a specific amount of graphite to a specific condensed polycyclic polynuclear aromatic hydrocarbon resin. CONSTITUTION:The objective holding material is produced by compounding (A) a condensed polycyclic polynuclear aromatic hydrocarbon resin having a flow point of <=150 deg.C and an acid-infusibilizing ratio of >=50% in water and produced by reacting (i) a raw material consisting of a condensed polycyclic aromatic compound (or its mixture with a monocyclic aromatic compound) with (ii) a crosslinking agent consisting of an aromatic compound having plural hydroxymethyl groups or halomethyl groups in the presence of (iii) an acid catalyst such as polysulfonic acid resin or a hydrophobic organic sulfonic acid with (B) 5-70wt.% of graphite powder. |
