NeXolve Thermalbright® C Polyimide Film
Categories: Polymer; Film; Thermoset; Polyimide, TS; Polyimide, Thermoset Film

Material Notes: High performance white polyimide film.

Thermalbright® Polyimide is a high performance white polyimide film with wide ranging uses in display applications, electrical insulators, composites, industrial tapes, space structures, and many others. Thermalbright® Polyimide is useful in thermal control applications requiring low absorptivity, high emissivity, UV stability, and high temperature colorfastness.

Thermalbright® Polyimide exhibits high optical density and hiding, making it an excellent high temperature white paint replacement material. In addition to outstanding thermal and optical properties, Thermalbright® Polyimide exhibits the lowest moisture uptake of all commercially available polyimides, at 0.2%.

Thermalbright® Polyimide is available in two grades: Thermalbright® C for Electrostatic Dissipative (ESD) applications, and Thermalbright® N for applications that require electrical insulation. Continuous rolls are available now in 1 mil thickness (25 micron) and in widths up to 60 inches (152 cm).
