“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.

"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.
