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.

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.
