Heat Measurement Film
- Brand：日本FUJIFILM
- 富士熱量測量膠片，熱分布測試紙。
- Thermoscale 200C can be used for higher temperatures (150°C to 210°C). Thermoscale is ideal for applications involving analysis of heat distribution during press, roll, and laminate processes and in drying ovens.
- The extent of color change depends on the temperature of the heat source and the contact time. Even at the same temperature, a shorter contact time produces paler colors with a blue tint and the increasing contact time makes the colors deeper with a red tint.
- The color change is also influenced by factors such as the type of material on the opposite side (i.e., the non-heat source side), thermal characteristics, contact pressure and air flow, so calibration should be performed under actual usage conditions.
- The base film is coated with a thermosensitive color-forming layer and a protective layer, as shown in the figure above. Touch the non-glossy surface to the heat source and observe the the glossy side of the sheet to see the color patterns that represent heat distribution.
- Heat melts the developer and makes the microcapsule walls permeable, allowing developer to enter the microcapsules, where it reacts with the color-forming agent to produce color.
