Tactile Pressure Indicating Sensor Film
Pressurex is a thin flexible mylar film that reveals pressure distribution and magnitude between any two contacting
surfaces. Pressurex can assess both bolting patterns and the number of bolts required to achieve a satisfactory seal and
improve quality in both design integrity and production of components and products with gasketed and flanged surfaces.

Example Usage of Pressurex Film Placed Across an Engine Head Gasket |
Upon the application of force the microcapsules rupture, producing an instantaneous and permanent color change. Like
Litmus paper, the color intensity of Pressurex is quantifiable; the color intensity reveals precisely what pressure level (PSI
or kg/cm²) was applied at any discrete point on the surface of the film.
