Brushes for FHP motors

Mersen carbographitic and bakelite-graphite brushes for FHP motors

Mersen offers a wide range of carbographitic, bakelite-graphite and metal-graphite brushes for FHP motors.  

  • Carbographitic grades are prepared from carbon and coke powders (natural or artificial) agglomerated with appropriate binders to give them good resistance to high temperature and variable loads.
  • Bakelite-graphite grades are made from natural or artificial graphite powders agglomerated with a thermo-hardening resin to give them a high electrical and mechanical resistance power.
  • Metal-graphite grades: powdered natural or artificial graphite is mixed with a thermo-setting resin, copper powder, and/or other metal powders. The mix is then pressed and polymerized at a suitable temperature in an inert atmosphere.
