TOMOEGAWA designs and develops various functional materials according to customer requests. ​ We create sheets with a variety of functions through contract manufacturing or collaboration using customer-supplied or specified materials. ​ Customization of various properties is also possible by controlling fiber diameter, thickness, and porosity. ​ Please share your requirements with us.

“We would like to use functional powder with properties such as moisture absorption, deodorization, antibacterial effect, adsorption, and purification. However, handling the powders as is can be problematic.”​ Are you facing any of these issues? ​ Utilizing our papermaking technology, we convert functional powder such as resins, metals, and minerals into sheet form. [Features]​ 1. Maximizing the unique properties of powder​ At our company, we produce sheets by incorporating powder into fibers using a papermaking process. ​ Therefore, compared to the conventional method of coating powder with binder resins for coating, our process enables the properties of the powder to be maximized. ​ 2. High-density retention of powder within the sheet As a specialty paper for multiple industries manufacturer, we have refined our papermaking technology for over 100 years. ​ Leveraging the expertise developed during this time, we are able to hold powder within the fibers at a remarkably high density. ​ ​[Examples of powder Characteristic Utilization]​ ・ Moisture absorption​ ・ Adsorption of gases, etc.​ ・ Purification of water, soil, etc.​ ・ Deodorization and odor prevention​ ・ Antibacterial, antiviral, etc.

TOMOEGAWA's Copper Fiber Sheet is a 100% copper sheet. Sheets produced using papermaking technology combine “the electrical conductivity and thermal conductivity of copper” and “the porous and cushioning properties of paper”. [Features] 1. High heat dissipation properties The specific surface area is approximately 10 times geater than that of copper foil, resulting in high heat dissipation due to its porous structure. 2. Flexibility like paper It is highly flexible and can absorb thermal dimensional changes caused by differences in the coefficient of linear expansion. 3. Lightwight and thin Approximately 1/3 the weight of bulk copper foil of the same volume due to its porous structure. Also, it can be used in thickness of 100 μm or less, contributing to product weight reduction and space savings. 4. Customizable of various characteristics. Customization according to the required properties is possible by controlling fiber diameter and thickness. [Application] - Heat dissipation modules - Electrode related materials

[Features] - Being lightweight and flexible, it contributes to space saving and design freedom of the product - Adhesive can penetrate the porous parts, making it effective for creating a strong bond - Its high heat, water, and chemical resistance make it suitable for use in harsh environments such as vehicles and outdoor applications - Customization according to the required properties is possible by controlling fiber diameter and thickness. [Application] - Flexible Planar Heater - Lightweight and thin electromagnetic wave shield materials - Acoustic transmission boards that reduce wind noise

"We want to simplify the production process for Cards and tags with embedded IC chips."​ Do you have any such concerns? ​ Conversion sheets are made by blending pulp fibers with resin fiber. ​ Due to the use of pulp fibers, these products are highly cushioned and exhibit excellent ability to fill in uneven surfaces. ​ Therefore, when electronic components (such as IC chips) are sandwiched and laminated with heat, it is easy to create planar shapes. ​ [Other Features]​ Temperature processing from 80 ℃ is possible ​ Before heating, the material is flexible and can be easily processed like paper. ​ When heat is applied, it exhibits property changes similar to plastic sheets while maintaining water and heat resistance. ​ With a pulp fiber content of over 51%, it contributes to plastic reduction. [Application]​ - IC cards​ - IC Tag​ - Reduces environmental impact as a substitute for plastic products, etc.

These products are sheets made by adding a small amount of organic binder to various inorganic (ceramic) fibers such as rock wool, AES (alkali Earth Silicate) fiber, alumina fiber, and others. It equipped with cushioning and flexibility and can be customized to a range of thicknesses and hardness levels.​ * Since these products contains an organic binder, smoke or gas may be generated during initial heating.

Features 1: Excellent heat resistance​ - Primarily composed of rock wool, offering heat resistance up to 1000°C.​ ​Features 2: Low Shot Content​ - Compared to general rock wool (slag wool) products, it contains less shot (un-fiberized material), resulting in a smooth surface.​ ​ Features 3: processability and Flexibility​ Can be easily cut with scissors or a cutter.​ The hardness of the sheet can be controlled, making it possible to meet needs such as punching and winding properties.​ 　(Sheet thickness: 0.5–6 mm. For other sizes, please inquire. Sheet width: up to 1,260 mm)​ ​*For physical property technical data, please refer to the detailed information.​ ​- Sheet thickness: 1 to 6mm​ - Sheet width: 630 mm to 1,260 mm​ *For details regarding thickness, width, or length other than those listed above, please feel free to contact us. ​ *Please note that smoke or gas may be generated during initial heating due to the inclusion of organic binder.​
