NeXolve LaRC™-CP1 Polyimide
Categories:	Polymer; Film; Thermoset; Polyimide, TS; Polyimide, Thermoset Film
Material Notes:	Transparent polyimide with low moisture uptake and low dielectric constant. Transparent polyimide with low moisture uptake and low dielectric constant. LaRC™ CP1 exhibits the lowest moisture uptake, lowest dielectric constant, and lowest color of all commercially available polyimides, making it an ideal choice for electronics, displays, and aerospace applications. Additionally, continuous rolls are available now in thicknesses as low as 2.5 microns (0.1 mil) and in widths up to 60 inches (152 cm). Information Provided by NeXolve Corporation.
