LOW DIELECTRIC INSULATING PAPER AND MANUFACTURE THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a low dielectric sheet having superior heat resistance and dimensional stability. SOLUTION: A fluororesin and polyparaphenylenebenzobisoxazol are contained in a paper substance as main ingredients. This dielectric insulating paper contains the fluororesin in an amount of 95-5 wt.% of the total weight of the paper substance and the polyparaphenylenebenzobisoxazol in the amount of 5-95 wt.% of that.
