Electronic Products Introduction
Electronic Wire and wiring materials

Electronic Wire

A wide variety of electronic wiring for many applications including computers and computer peripherals, and motors and component assemblies for various appliances. In addition, wires with characteristics including high-speed data transmission and high heat resistance are available for areas that require high performance, such as automotive applications.

Flexible Printed Circuit and wiring materials

Flexible Printed Circuit

Flexible printed circuits (FPC) are made of fine conductive circuits patterned on thin insulating film. FPCs are major electronic components which are used in smartphones, information and communication equipment and other advanced devices. Through continuous R&D we can timely address the need for miniaturization, lighter weight, and higher functionality in your application.

Heat-shrinkable tubing (SUMITUBE™) and wiring materials

Heat-shrinkable tubing (SUMITUBE™)

SUMITUBE™ is a versatile heat-shrinkable tube that takes advantage of plastics' shape-memory effect enabled by electron beam irradiation. It's made primarily from polyolefin, fluorinated polymer, and thermoplastic elastomer. Applications include wire and wire harness bundling, insulation, and protection from heat, oil, and chemicals.

Nickel Alloy, Cladded, Plated Wire and wiring material

Nickel Alloy | Cladded/Plated Wire

A variety of alloy wires and plated wires for use as EDM (Electrical Discharge Machining) wires, and lead wires in automotive and electronic components. Examples include nickel alloy wires with excellent heat resistance and thermal coefficient that closely matches glass. These are derived from our expertise in alloys, metal composites, and metal surface treatment.

Porous Metal (celmet), Electroplated Wire and wiring materials

Metal Foam (Celmet™) | Electroplated Wire

Celmet™ is a Metal Foam with a sponge-like, three-dimensional frame that results in a large surface area. Applications include usage as electrodes of Ni-MH batteries for hybrid vehicles and current collectors in fuel cells. Electroplated wires are used as terminals of electronic components.

Thermoplastic Molded Components (Teralink™), wiring materials

Thermoplastic Molded Components (Teralink™)

Teralink™ are thermoplastic molded components cross-linked by irradiating electron-beam. The benefits of sliding grade Teralink™ S include high fatigue strength, low abrasion loss, and low friction coefficient. It has longer service life than conventional nylon and POM. Components such as smaller (space-saving), more durable gears are available.



POREFLON™ is porous membrane made of PTFE. PTFE stands for PolyTetraFluoroEthylene, it is a kind of fluororesin. It features chemical resistance, heat resistance, water repellency, high retention of very small particles and high flow capability.

The Cross Linked Fluorine Resin FEX™

The Cross Linked Fluorine Resin FEX™

FEX™ is a functional fluororesin coating technology which takes advantage of the low coefficient of friction of conventional flurororesins while showing an exceptional improvement in wear resistance. There is a FEX™ tape which has the low coefficient of friction and high wear resistance. It is based on our state of the art electron beam cross- linking technology combined with our original fluororesin coating techniques.
