Count on our measurement consignment services of thermal conductivity and thermal diffusion rate!

Sheets(Various orientation)
  • Graphite Sheet
  • Polyimide
  • PVC
  • Silicon heat dissipation sheet
  • CNT
  • etc.

In many cases, the samples in the shape of sheets have various orientations. You need to know which sample has what types of orientations. The thermal conductivity of composite materials varies with which fillers, such as AlN, SiO2, SiO, CNT, and etc are used.
