PURPOSE:To provide a compsn. which exhibits excellent sliding characteristics without abrading or damaging a mating material. CONSTITUTION:This compsn. comprises a polyethersulfone resin as a base material, a polyetetrafluoroethylene powder, and an arom, polyester powder. The compsn. is excellent in sliding characteristics because the polyester powder, having a cleavage structure, imparts abrasion resistance to the compsn., while the polytetrafluoroethylene powder migrates and adheres to a mating material on sliding to thereby reduce the abrasion of the material and impact a stable, and low coefficient of friction thereto. |
