Periodical Heating Method Thermal Diffusivity Measurement System
FTC series
Easily evaluate thin film materials that are difficult to measure with the flash method
This system measures thermal diffusivity in the thickness direction of solids such as film polymers, paper, and ceramics by using the AC joule heating method.
With specialized in room temperature measurement only, which is highly needed, a compact body and low cost have been achieved.
Applications
- Thermal diffusivity measurements of film materials (thickness direction)
- Polymer films, heat dissipation sheets, electronic device materials, conductive materials, power devices, and other polymer materials
Features
- Compared to the flash method, the thickness limitation of the sample is one-half or less, making it optimal for thermal property evaluations of thin polymer materials
- For polyimide-based samples, 10 µm to 200 µm
- The detector has been widened so that it can measure at the surface of the sample, so measurements have high reproducibility
- Power saving (100 VAC 15 A, excluding computer)
- The installation area is about the size of A3 paper, less than half of the size of our conventional model (FTC-1)
