**Features** 1. By selecting injection-molded pellets and thermally weldable films as the film layer of Arset, heterogeneous bonding of metal and resin can be achieved within the mold. Since it is welded solely by heat, no pre-treatment of the metal or resin is necessary. 2. Because no adhesives are used, there is no concern about cohesive failure at the adhesive layer even when processed into complex shapes. 3. Since the film is laminated onto the metal, subsequent processes such as insulation and metal protection that require applying films are unnecessary. 4. Since the film is laminated onto the metal, printing that cannot be done directly on the metal can be applied.

Aruset is a composite material that strongly laminates metal and resin film without using adhesives. You can choose the combination of metal and film according to your preferences. 【Features】 ■ Omission of the insulating film lamination process ■ Omission of the metal coating process ■ Miniaturization and space-saving of components (reduction of insulation distance) ■ Compatibility of insulation and heat dissipation (compared to resin) ■ Joining metal and resin using only heat 【Exhibition Information】 Aruset will be exhibited at "Nepcon Japan" as a suitable material for next-generation laminated busbars.

We propose wedge paper made of PEI resin film as insulation material for EV traction motors, and slot paper made of adhesive-free aramid paper composite. Wedge paper offers excellent buckling resistance, while slot paper achieves high coil filling and improved packing density through the use of adhesive-free thin films. Our unique material design and adhesive-free composite technology enhance the insulation performance of thin film aramid paper composites. 【Features】 - Wedge paper: Excellent buckling resistance, enabling high coil filling - Slot paper: Achieves both thin film structure and insulation performance/strength through adhesive-free composition - Good adhesion with aramid paper compared to competitor products - Material that is less likely to break when inserted into the stator *For more details, please download the PDF or feel free to contact us.

We would like to introduce the "insulating material that combines heat dissipation, high rigidity, and heat resistance" that we handle. For motor insulation applications, it features heat resistance (200°C), thin film (minimum 100μm), heat dissipation (up to 0.8W/m·K), bendability, and insulation properties. As part of our lineup, we offer two types: "HD01B," characterized by high rigidity and thin film, and "HD03," characterized by high heat dissipation and bendability. 【Features】 ■ Heat resistance (200°C) ■ Thin film (minimum 100μm) ■ Heat dissipation (up to 0.8W/m·K) ■ Bendability ■ Insulation properties *For more details, please download the PDF or feel free to contact us.

"Arusetto" is a composite material that strongly laminates metal and resin film without using adhesives. By laminating thin copper through an insulator, the effects of the skin effect are reduced, which can suppress heat generation. It can be used for laminated rigid busbars and flexible busbar applications. *For more details, please download the PDF or feel free to contact us.

"Arusetto" is a composite material that strongly laminates metal and resin film without using adhesives, and it is intended for application in laminated flat copper wire for motors. Eddy currents are generated within the flat copper wire due to the magnetic flux from the rotor and the adjacent slot. By using laminated flat copper wire, we can expect to suppress these eddy currents. *For more details, please download the PDF or feel free to contact us.*
