HIGHLY FUNCTIONAL ELECTRIC-ELECTRONIC INSULATING MATERIAL, INSULATING SYSTEM AND ELECTRONIC DEVICE

摘要

PROBLEM TO BE SOLVED: To obtain a highly functional electric-electronic insulating material which can improve the reliability of an electronic equipment for long period of time by use of an effective insulating tape (or insulating sheet) in an external peripheral insulator in a roter of motor. SOLUTION: An ultra-violet light hardening type synthetic resin (b), having an excellent transmission property to ultra-violet light and low dielectric property, is formulated with fine particules, and the resin is used as a prepreg impregnating agent or coating agent for an organic or inorganic type substrate (a), or as a plastic film, then the impregnated or coated material is hardened by irradiating ultra-violet light for a short time under separatorless and non- adhesive conditions at an ambient temperature to obtain the insulating tape or the insulating sheet, which can be used for an electric-electronic insulating material.
