Lucky Pressure Measurement Film allows you to easily measure pressure balance, distribution, and size. Created using Lucky’s advanced thin film coating technologies, the pressure inspection sensor on the entirety of the film allows you to confirm pressure distribution of the entire surface at a glance. The color appears red where pressure is applied, and the color density varies according to the amount of pressure.
The LUCKY pressure indicating film is composed of two films, which are respectively coated with color-forming material and color-developing material. This type is used by placing the sides coated with the chemical agents over each other
The microcapsules in the color-forming layer are broken by pressure, and the colorless dye is absorbed into the developer, causing a chemical reaction to produce a red color. The microcapsules containing the color-forming material are adjusted to varying sizes and strengths, and is coated uniformly, producing a color density that corresponds to the amount of pressure.
