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
