Visualizing of pressure, heat and UV light

Distribution Measurement Film


Film that makes the pressure distribution visible through color generation where pressure is applied

With this film, red color is generated where pressure is applied, and it is possible to measure the pressure level by its color density. There is a total of eight kinds, including two-sheet types handling low to moderate pressure (4LW to MW) and mono-sheet types handling moderate to extremely high pressure (MS to HS to HHS).

Pressure color-generation mechanism

When pressure is applied, microcapsules in the color-forming layer break and the colorless dye comes out to react with the color-developing material, causing red color to appear.

Film that makes the heat distribution visible through color generation where heat is applied

This film measures heat distribution using color changes. The color generated differs depending on the heat-source temperature and contact time. There are two kinds, one for lower temperatures (80-105°C) and one for higher temperatures (150-210°C).

Heat color-generation mechanism

When heat applied, the color-developing material melts and microcapsule walls become permeable. The color-developing material enters the microcapsules, reacting with the color-forming agent to generate color.

Film that reacts to UV light, making the UV light amount distribution visible

This film measures the exposed surface as a whole by changing color density in response to the amount of UV light. There are three kinds for use depending on cumulative light amount, one mono-sheet type for low light amounts and two-sheet types for moderate to high light amounts.

UV light color-generation mechanism

Color is generated when the developer and dye in micro capsules react to UV light exposure. Through the establishment of a photosensitive layer and white layer in the support medium, color density variations are generated depending on light amount.
