Pressurex® is a thin flexible Mylar film that reveals pressure distribution and magnitude between any two contacting
surfaces. The film is useful in lamination applications that are either static or moving. In a static lamination, Pressurex can identify misregistration, parallelism problems or press platen defects. In moving laminations, Pressurex can determine roller parallelism problems and roller defects at the nip point.
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.
