Pressure-Sensitive Film

Pressurex, a thin sensor film, maps and measures pressure distribution and magnitude between any mating, contacting, or impacting surfaces.

The film reveals force distribution in problem contact areas within gasket and O-ring seal assemblies, and aids in the design and production of gasketed and flanged surfaces. The film detects pressure from 2 to 43,200 psi (0.14 to 3,037 kg/cm2). Applications include assessing surface contact inconsistencies in gaskets, clamps, bolted joints, heat-sealing elements, lamination presses, nip rolls, welding heads, clutch and brake assemblies, tire treads, connectors, and heat sinks. The film comes in large, thin clear Mylar sheets. When placed between impacting/mating surfaces, the film's color intensity changes in proportion to the specific pressure applied.
