One of the characteristics of mica is its insulating properties! It is also resistant to heat and difficult to conduct electricity! It is used in various places, mainly in electronic devices and home appliances, as an insulating material!

Electrical Insulation Due to its high electrical insulation properties, it is used in electrical components and home appliances. Mainly, it is used in home appliances, electronic device components, specialty paper, coatings, semiconductor-related products, etc. Because it is easy to process, it is found in various places, from familiar everyday items to niche applications. *We handle a variety of mica products in different sizes and grades, primarily focusing on Muscovite (S grade) and Phlogopite (M grade). Mica has good compatibility with various materials such as plastic resins, paints, rubber, films, sealing materials, and adhesives.

General grade with high purity and high aspect ratio. Phlogopite, derived from the Greek word phlogopos meaning "like flame."

The "Repkomica S Series" is a product made from natural mica that has been refined and crushed at a domestic factory. It maximizes the high elasticity inherent in natural mica through manufacturing techniques developed over many years, resulting in a high aspect ratio (average particle size/thickness), which is a key feature of flake fillers. By being incorporated into industrial materials such as plastics, paints, and rubber, it is expected to provide various functionalities centered around rigidity, dimensional stability, and heat resistance. 【Features】 ■ Long-term supply stability due to abundant reserves ■ Quality stability through domestic production system ■ No crystalline silica detected (detection level: below quantification limit) ■ Various grades available based on average particle size ■ Flexible response to custom grade orders and surface treatments ■ Short delivery times supported by domestic bases Please feel free to download for more detailed information. 　　　　　　　　　↓↓↓↓↓↓↓

Demonstrates high cost performance! Easily applicable to products that require high whiteness and colorability.

The "Repkomica M Series" is a product made from naturally occurring muscovite that has been refined and crushed at a domestic factory. It has a high whiteness and can be easily incorporated into products that require coloring. Additionally, it excels in insulation resistance, making it particularly effective for applications such as electronic components. When filled into industrial materials like plastics, paints, and rubber, it is expected to enhance and impart properties such as rigidity, dimensional stability, and heat resistance. 【Features】 ■ High whiteness allows for easy incorporation into products that require coloring ■ Excellent insulation resistance ■ Particularly high performance in applications such as electronic components ■ Expected to enhance and impart properties like rigidity, dimensional stability, and heat resistance ■ Flexible response to surface treatment and custom grade production ■ Short delivery times supported by domestic facilities

◆Developing a stable supply system centered around our domestic factories ◆High cost-performance due to processing raw materials with dry grinding! ◆Custom-made products are also available

"Mica" is a mineral classified as a silicate aluminum compound. The mica products we handle are high-purity, high-quality, and high-aspect-ratio flake powders, and we have established a stable supply system centered around our domestic factory. We offer a wide range of grades with average particle sizes from several micrometers to several hundred micrometers, allowing for flexible responses tailored to our customers' applications and requests. Additionally, since we mainly process raw materials for dry grinding, we achieve high cost performance. 【Features】 ■ A mineral classified as a silicate aluminum compound ■ Non-toxic to humans and eco-friendly ■ High-purity, high-quality, high-aspect-ratio flake powders ■ A stable supply system centered around our domestic factory ■ Flexible responses tailored to customers' applications and requests Please feel free to download detailed information. 　　　　　　　　　↓↓↓↓↓↓↓

JOHNAN has released a video that clearly explains the implementation technology for stretchable films, which are expected to be utilized in wearable devices and medical equipment. In the video, you can see how the film, which has excellent elasticity, stretches and contracts. Please check our high technological capabilities and the flexible characteristics that are useful for product development. We hope this will help you generate new ideas in product development. ▼You can watch the video here [Link to the implementation page for stretchable films] https://www.johnan.com/dms/mounting/filmdevic/stretchable/

Thank you very much for your continued support. We sincerely apologize for the inconvenience, but our company will be closed for summer vacation during the following period. 【Closure Period】 From Saturday, August 9, 2025, to Thursday, August 14, 2025. We will resume normal business operations on Friday, August 15. We appreciate your understanding during this time and apologize for any inconvenience caused.

"Because it's an invisible place, we won't overlook it." Japan's climate is characterized by high temperatures and humidity, and particularly after typhoons and heavy rains, the conditions can be harsh for homes. It's not just the roofs and exterior walls that are affected by rain and wind. The area beneath the floor is actually the most susceptible and often overlooked point. This time, we will explain the "checkpoints for under the floor" that should be confirmed after a typhoon or heavy rain, the "responses" if abnormalities are found, and measures for preventing recurrence. [Table of Contents] ■ Why is underfloor checking necessary? ■ Checkpoints to confirm after a typhoon or heavy rain ■ Responses when damage is discovered ■ Points for preventing recurrence ■ Suggestions from Seihou Products ■ Summary Please be sure to read the [related materials] and [related links]. ↓ ↓ ↓

Explosion-proof motors available in stock We will deliver within 7 days to meet your delivery schedule. 【What is an explosion-proof motor?】 In factories and plants, flammable gases and vapors are present. When these mix with air and come into contact with an ignition source, an explosion or fire can occur. This motor is designed with measures to eliminate such ignition sources. 【Available stock models】 ■ Pressure-resistant explosion-proof motors, explosion-proof grade d2G4 - Foot-mounted type, output 0.4 to 3.7 kW, 4 poles - Flange type, output 0.4 to 0.75 kW, 4 poles ■ Increased safety explosion-proof motors, explosion-proof grade eG3 - Foot-mounted type, output 0.2 to 0.75 kW, 2 and 4 poles - Flange type, output 0.2 to 0.75 kW, 2 and 4 poles

As part of the "Hometown Ibara Future Creation Human Resource Development Project," we welcomed local elementary and middle school students to the special summer program "Ibara Job Exploration Tour 2025," a collaboration between the Ibara City Chamber of Commerce and the Corporate Branding Committee. We conducted a presentation that clearly and enjoyably introduced how our technology supports society, allowing the children to learn about the appeal of manufacturing and the significance of working while interacting with actual devices and products. Through this initiative, we hope to deepen our connection with the community and nurture the curiosity of the children who will carry the future. We sincerely thank everyone who participated, as well as all those involved in planning and organizing the event.
