ABSTRACT:
The present invention is a polymeric composite comprising a polyimide component and a fluoropolymer component derived from a micro powder. The fluoropolymer micro powder has a melt point between 250 and 375° C. The fluoropolymer micro powder has an average particle size between 20 and 5000 nanometers (5.0 microns).The polyimide component and the fluoropolymer component are inter-mixed at a high dispersion level where the fluoropolymer component is present in a weight ratio from 10 to 60 percent. The polymeric composite of these two components is particularly useful in the form of a thin film used in high-speed digital circuitry or high signal integrity for low loss of a digital signal. The film can also be used as a wire wrap, or as a coverlay or base film substrate for flexible circuitry laminates.
