Application area of CNT pasteConductive paste?
-low contact resistance and stable -good electric conductivity and
heat conductivity.
Conductive materials for electric contacting devices that perform mechanically switching and contacting the
electric circuit. conditions
-no variation in the face of contact
We use a carbon nanotubes(CNTs) as a conductive filler
Good conductivity at very low concentration of CNTs
