摘要： PROBLEM TO BE SOLVED: To obtain an insulation tape for a flat cable with good adhesive property with a conductor in both ranges of heat-resistant and cold-resistant temperatures by providing an adhesive layer laminated on an insulation base material made of a polyolefine adhesive resin bridged at its specific gel percentage. SOLUTION: A polyolefine adhesive resin is extruded and laminated on one side of an insulation base material such as polyimide film, for example, by means of T dye extrusion method, etc., and the insulation base material and the adhesive layer are integrated as a laminated layer. The thickness of the adhesive layer is generally limited to approx. 5 to 100μm. Then, the polyolefine adhesive resin of the adhesive layer is bridged so that the gel percentage is 20 to 70%. If the gel percentage is less than 20%, the heat resistance is insufficient and if it exceeds 70%, the adhesive property becomes worse. It is particularly preferable that the gel percentage be 30 to 60%. Thus, a target flat cable insulation tape can be obtained.

摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method capable of providing an electret material having an excellent charge-retentive property with respect to heat.
SOLUTION: The method for manufacturing an electret material includes: an irradiation step, a formation step and a charging step. In the irradiation step, a dispersion containing polytetrafluoroethylene microparticles is irradiated with γ-ray. In the formation step, the dispersion that has been irradiated with γ-ray is applied on an electrode plate, and thereafter dried, and the polytetrafluoroethylene microparticles are baked, thereby forming a polytetrafluoroethylene layer on the electrode plate. In the charging step, the surface of the polytetrafluoroethylene layer is subjected to a charging treatment.
