The present invention relates to an aluminum-resin composite and provides the aluminum-resin composite which is excellent in adhesive property between metal and resin and is applicable to a continuous production process such as a wire production process. Specifically, the present invention uses the aluminum-resin composite including a metal made of aluminum or an aluminum alloy and resin adhering to the metal via an alumina nanoporous layer formed on a surface of the metal. The alumina nanoporous layer contains alumina nanoparticles of 5 nm to 10 nm in average particle diameter and holes three-dimensionally communicating with one another.

An insulated wire, which is coated, on a conductor, with a thin-film insulating layer composed of a resin dispersion, wherein the resin dispersion contains:

Insulated wire and resin dispersion

A thermoplastic resin foam which has both high reflectance and superior shape-retention properties, suitable for use in backlights and illumination boxes for illumination signboards, lighting fixtures, displays and the like. The thermoplastic resin foam is manufactured by a manufacturing method including a procedure for holding a resin sheet composed of thermoplastic resin (A) and thermoplastic resin (B), which has a functional group having an affinity with thermoplastic resin (A), within a pressurized inert gas atmosphere to enable the resin sheet to contain inert gas, and a procedure for foaming by heating the resin sheet containing inert gas at a temperature higher than the softening temperature of thermoplastic resin, under normal pressure.

Thermoplastic resin foam

A multilayer insulated wire has a conductor and two or more extrusion-insulating layers to cover the conductor, wherein at least one layer of the insulating layers other than an innermost layer is formed by a resin mixture containing a polyphenylene sulfide resin (A) as a continuous phase and an olefin-based copolymer ingredient (B) as a dispersed phase, or wherein at least one layer of the insulating layers other than an innermost layer is formed by a resin mixture containing a polyphenylene sulfide resin (A) as a continuous phase, and an olefin-based copolymer ingredient (B) and a polyamide (E) as a dispersed phase; a transformer is made by the multilayer insulated wire.

Multilayer insulated wire and transformer made using the same

A multilayer insulated wire having two or more extrusion-insulating layers provided on a conductor to coat the conductor, wherein at least one layer of the insulating layers is composed of a polyethersulfone resin (i), or a resin mixture (ii) made by blending: 100 parts by weight of a resin (A) of at least one selected from polyetherimide resins and polyethersulfone resins, and 10 parts by weight or more of a resin (B) of at least one selected from polycarbonate resins, polyarylate resins, polyester resins and polyamide resins; and wherein at least one layer other than the insulating layer composed of the resin (i) or resin mixture (ii) is provided as an outer layer to the insulating layer and is composed of a polyphenylenesulfide resin. A transformer can also have the mentioned multi-layered insulated wire.
