★Maika News★ Excellent rigidity (bending elasticity) and dimensional stability! It suppresses molding shrinkage ★Repco News★

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

The "Repkomica S Series" is a product made from naturally occurring mica that has been refined and crushed at a domestic factory. It maximizes the high elasticity inherent in 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. When incorporated into industrial materials such as plastics, paints, and rubber, it is expected to impart 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 high-performing in applications such as electronic components. When filled into industrial materials like plastics, paints, and rubber, it is expected to improve and impart properties such as rigidity, dimensional stability, and heat resistance. 【Features】 ■ High whiteness and easy incorporation into products requiring coloring ■ Excellent insulation resistance ■ Particularly high performance in applications such as electronic components ■ Expected to improve and impart properties such as 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, high-aspect-ratio flaky powders, and we have established a stable supply system centered around our domestic factories. We offer a wide range of grades with average particle sizes from a few 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 ■ Harmless to the human body and eco-friendly ■ High-purity, high-quality, high-aspect-ratio flaky powders ■ A stable supply system centered around our domestic factories ■ Flexible responses tailored to customers' applications and requests Please feel free to download for more detailed information. 　　　　　　　　　↓↓↓↓↓↓↓

The rigidity (bending elasticity) that is a characteristic of mica! It also has a small molding shrinkage rate and excellent dimensional stability, making it suitable for various industrial parts!

Rigidity (Bending Elasticity) Improves the strength of the product and allows it to withstand bending and twisting. Dimensional Stability Reduces shrinkage rates to prevent warping and cracking, and minimizes molding shrinkage to provide surface reinforcement effects. Mica balances molding shrinkage in both the MD (machine direction) and TD (transverse direction). Due to the above characteristics, it is used in various applications such as automotive parts, electronic devices, films, marine coatings, exterior materials, interior materials, sealants, adhesives, gasket materials, and friction materials.

Japan is one of the top 10 countries in the world with frequent earthquakes. The 2020 White Paper on Land, Infrastructure, Transport and Tourism has also reported an increase in the probability of major earthquakes occurring. Regarding the Nankai Trough earthquake, the probability of an earthquake with a magnitude of 8 to 9 occurring within the next 30 years is estimated to be 70 to 80%. At Hotron, we recommend the introduction of seismic devices for earthquake countermeasures in buildings and equipment. The seismic device 'HK-2' is a product that automatically performs various controls that have been pre-set when it detects strong shaking equivalent to a seismic intensity of 5 lower or higher. For example, it can automatically execute actions such as: "Open automatic doors and gates to secure evacuation routes and access for emergency vehicles" "Transmit signals to the control room and stop facility equipment" "Unlock the keys to locked lockers" "Automatically play voice guidance" For more details, please download the materials or contact us.

At the entrance of a real estate company in Minato-ku, Tokyo, we have introduced the rental service "Majesta Fragrance" for commercial aroma diffusers, creating a fragrant atmosphere in the space. With the new start of the office relocation on April 1st, a high-quality and sophisticated scent suitable for this new beginning is spreading throughout the entrance. The "scent" that visitors first experience is one of the important elements that naturally conveys the company's impression and dignity. At Majesta Fragrance, we support the enhancement of corporate branding value through the production of scents tailored to the spatial concept. We also offer a free trial installation, so please experience the atmospheric effects that scent can bring. If you are interested in scent design, please feel free to contact us.

We will be exhibiting at the Thermal Tech 2026 event held at the Osaka Industrial Creation Center. At this exhibition, we will introduce our unique material technologies to engineers who face challenges in material selection for high-temperature environments, focusing on polyimide sheets suitable for high heat resistance and insulation applications. As attendance is by prior registration, please register through the related link before visiting, and we hope you will stop by our booth.
