Abstract

An apparatus in which an electrically conductive contact is in slidable contact with a polymeric composition comprising thermoplastic polymer, a fibrous reinforcing agent, and a mineral filler. The Mohs hardness of the electrically conductive contact is within 1 unit of the Mohs hardness of the mineral filler.
