Abstract
A composition suitable for the production of current-collecting brushes having improved wear-resistance comprises carbon or graphite and one or more of polytetrafluoroethylene, bromo-, iodo- or chloro-substituted derivatives of polytetrafluoroethylene, and wood-filled thermosetting resins. Examples describe compositions containing graphite and polytetrafluorethyene and one or both of wood-filled phenol-formaldehyde moulding powder and copper powder.
