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. It enables busbars that support high current and high frequency for EV applications, while also allowing for weight reduction. Its flexibility eliminates cracking due to vibrations in automobiles. Event Name: 39th Nepcon Japan Electronics Development and Implementation Exhibition (26th Electronic Components and Materials EXPO) Date: January 22 (Wednesday) to 24 (Friday), 2025 Venue: Tokyo Big Sight, East Hall 3, E21-2 *For detailed specifications, please download the PDF.

• Capacitor

**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.

The composite film type of "Keiju TM" is a variant of the single-layer film type. With the composite film type, while maintaining the cushioning properties of silicone rubber, it suppresses unnecessary stretching due to the presence of a substrate, preventing lateral displacement of the workpiece during pressing and improving secondary processing and handling. Additionally, the substrate and silicone are firmly bonded using special technology. We offer completely customized specifications tailored to your needs. 【Features】 ■ Thickness of silicone rubber: 30μm to 1mm ■ Thickness of substrate: 100μm, 50μm (the substrate is polyester film. Please consult us for other materials) ■ Rubber hardness: Shore A 20 to 70 (other hardness levels available upon request) ■ Product width: 300mm, 500mm ■ Surface condition: Flat, one side embossed ■ Layer composition: One side with substrate, both sides with substrate ■ Delivery form: Sheet, roll 【Examples of Use】 ○ Cushioning material for heat pressing 〇 Component materials for precision equipment *For more details, please contact us or download the catalog from the PDF. *There are no standard products. All items are made to order. Some combinations may not be available for supply. Thank you for your understanding in advance.

• Rubber

We would like to introduce two unique products developed by our company. "Keiju(TM)" is a high-temperature resistant cushioning material for press applications, created using our proprietary processing technology. It can accommodate ultra-thin thicknesses ranging from 50μm to 500μm and can be reused multiple times. Additionally, we have developed a "Flexible Epoxy Film" that excels in elasticity and flexibility. It is intended for a wide range of applications, including vibration damping for printed circuit boards and shock-absorbing materials for electronic components. 【Features】 <High-Temperature Resistant Cushioning Material "Keiju(TM)"> ■ Dust generation during processing is suppressed as it does not use non-woven fabric. ■ The material is backed, preventing the film from stretching in the plane direction during pressing and reducing lateral displacement. <Flexible Epoxy Film (Development Product)> ■ It has already cured, so it does not have a melting point and will not melt. ■ It does not contain low molecular weight siloxanes. *For more details, please refer to the materials. Feel free to contact us with any inquiries.

• Other polymer materials

In addition to the heat resistance and surface adhesion characteristics of epoxy resin, flexibility has been added. 【Features】 ■ Since it is already cured, it has no melting point and does not melt. ■ It does not contain low molecular weight siloxanes. ■ It excels in shock absorption and vibration damping properties. ■ It has excellent adhesion to CFRP prepregs and metals. ■ There is also an embossed type with reduced surface tackiness. ■ It is available in a thin film and can be delivered in roll form.

"Keiju TM" is a silicone rubber film created through our company's unique processing technology. We have developed a high-temperature grade in addition to the conventional grade. It can be repeatedly used in high-temperature environments (up to approximately 300°C). Since it is not disposable, it contributes to cost reduction and environmental impact reduction. Additionally, because it does not use non-woven fabric, there is no dust generation during the process. 【Features】 - The film is attached to a substrate, preventing lateral displacement of the workpiece during pressing as it does not stretch in the plane direction. - It can accommodate thicknesses from 50μm to 500μm (with a substrate thickness of 25μm). - By adjusting the thickness and rubber hardness, fine-tuning of pressure and sinking amount is possible. - Being a composite material with a substrate, it has rigidity and good handling properties. - Adjustment of the surface texture of the rubber is also possible. *Please feel free to consult us about the substrate-free option (single-layer silicone rubber film).
