Mersen offers a wide range of carbographitic and bakelite-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.
