Description

CircuitWorks® Conductive Grease, otherwise known as thermal greases, thermal gel, thermal compound, thermal paste, heat paste, heat sink paste or heat sink compound, are conveniently packaged in syringes for fast and easy application, and to reduce mess and wastage. The range covers a number of electronic production, rework and repair applications.

We offer three types of conductive grease:

  1. Silver Conductive Grease
  2. Boron Nitride Heat Sink Grease
  3. Silicone Free Heat Sink Grease

See the tabs below for more information.
