    • A resin-coated aluminum alloy sheet material for an aluminum electrolytic capacitor case has a superior formability even when being formed into an aluminum electrolytic capacitor case having a large height/diameter ratio, using a volatile press oil.A resin layer contains wax composed of at least one of polyethylene wax and carnauba wax, and has a thickness falling within a range from at least 2 μm to at most 22 μm. A total of lengths of wax particles, defined when the wax particles are cut along a straight line of 100 μm optionally drawn on the surface of the resin layer, is at least 10 μm. A number of the wax particles, featured by a cross-sectional shape having a size of at most 80% of the thickness of the resin layer and of at least 0.1 μm, is from at least 3 to at most 50. A number of the wax particles, featured by a cross-sectional shape featured by a major axis extent having a size of more than 80% of the thickness of the resin layer is less than 10. Although the resin-coated aluminum alloy sheet material is formed into an aluminum electrolytic capacitor case having a large height/diameter ratio, cracks and peelings do not occur in the resin layer.
    • 一种用于铝电解电容器壳体的树脂涂覆的铝合金板材即使在使用挥发性压榨油形成具有大的高/直径比的铝电解电容器壳体时也具有优异的成形性。 树脂层含有由聚乙烯蜡和巴西棕榈蜡中的至少一种构成的蜡,其厚度在2μm以上至22μm以下的范围内。 当蜡颗粒沿着树脂层的表面上任意拉伸的100米直线上切割时,蜡颗粒的总长度至少为10微米。 许多具有至少为树脂层厚度80%的至少为0.1μm的截面形状的蜡颗粒为至少3至至多50个。 具有由具有大于树脂层厚度的80%的尺寸的长轴范围的横截面形状的蜡颗粒小于10.尽管树脂涂覆的铝合金板材形成为铝 在高度/直径比较大的电解电容器壳体中,在树脂层中不会发生裂纹和剥离。

    • Provided is a multilayer insulated wire comprising a conductor and three or more insulating layers covering the conductor, in which each of first and second insulating layers, as counted from the conductor side, is (a) an extrusion-coating layer of an intimate resin mixture compounded so that an ethylene-based copolymer, having a carboxylic acid or a metal salt of the carboxylic acid on the side chain thereof, accounts for 5 to 40 parts by weight compared to 100 parts by weight of a thermoplastic straight-chain polyester resin, (b) an extrusion-coating layer consisting mainly of a thermoplastic straight-chain polyester resin formed by combining an acid constituent and an alcoholic constituent the whole or a part of which is cyclohexanedimethanol, or (c) an extrusion-coating layer of an intimate resin mixture compounded so that the ethylene-based copolymer, having the carboxylic acid or the metal salt of the carboxylic acid on the side chain thereof, accounts for 50 parts or less by weight compared to 100 parts by weight of the thermoplastic straight-chain polyester resin formed by combining the acid constituent and the alcoholic constituent the whole or a part of which is cyclohexanedimethanol, a third insulating layer being an extrusion-coating layer of a thermoplastic polyamide resin or a intimate resin mixture consisting mainly of the thermoplastic polyamide resin. Also provided is a bondable multilayer insulated wire which further comprises a bondable layer of an copolymerized-polyamide resin formed on the third insulating layer.
