"5% weight reduction temperature is 534℃!" This is an adhesive-free stainless steel/polyimide substrate suitable for high-temperature planar heating heater applications.

Kawamura Industries provides stainless steel/polyimide materials by leveraging the know-how of polyimide coating technology developed over many years on stainless steel foil. **Features of Kawamura Industries' 'SUS/Polyimide Material'** - Excellent heat resistance due to being adhesive-free → 5% weight loss temperature (534°C) - High adhesion strength achieved through unique polyimide technology → Stainless steel/polyimide adhesion strength (2.4 kN/m) - Wide range of thickness options → Stainless steel thickness (15, 18, 20, 30, 50 μm) → Polyimide thickness (selectable between 5-25 μm) *For examples of properties, please refer to the PDF document or feel free to contact us.*

The "vacuum hot press," which can also perform surface treatment in the previous process, and the "coating" technology for metal foils are suitable for the processing of electronic materials such as substrates for 5G and base materials for planar heating elements!

Kawamura Industries develops and manufactures materials for electronic applications and provides associated processing technologies. We will introduce technologies that have been adopted for substrates for 5G and materials for planar heating elements. 【Our Technology: Electronic Materials - Strengths of Vacuum Hot Press Coating Technology】 ■ Vacuum Hot Press In prototype and mass production using vacuum hot pressing, we can press without adhesives, allowing us to better utilize the inherent properties of the materials. (Note: We can also accommodate laminated products with adhesives.) - We have a large number of pressing machines, capable of handling various sizes and temperatures. - There are pressing machines installed in a cleanroom environment. ■ Resin Coating on Metal Foil Although we operate in a contract processing format, we can combine "metal foil + high-temperature treatment." - Our coating drying oven can handle temperatures up to 260°C, allowing for the drying of high-boiling point solvents. - We can also accommodate polyimide coating with a high-temperature curing oven that can handle up to 400°C. Including material procurement, we provide consistent support from small lots and prototypes to mass production, so please feel free to contact us. * We are currently publishing an introduction document summarizing what Kawamura Industries can do! You can view it immediately from [PDF Download].

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. We sincerely look forward to your visit. ◆ Our main exhibition content - PI Plates (Polyimide Laminates) - SUS/Polyimide Substrates ◆ Exhibition Details ◆ Exhibition Name: Thermal Tech 2026 (Pre-registration required) Pre-registration Method: Please register via the URL in the related link Date and Time: April 24, 2026 (Friday) 10:30 AM - 4:30 PM Venue: Osaka Industrial Creation Center, 3rd and 4th Floors (Reception on the 4th Floor)

From June 2025, measures against heat stroke in the workplace have become mandatory. Additionally, in December 2026, a "Support Package for Heat Wave Measures in Construction Work" was formulated, making heat stroke prevention during the summer a pressing issue, especially for those engaged in the construction industry. This time, we provide a collection of heat stroke prevention materials that can be utilized through Sysmet Co., Ltd.'s comprehensive weather platform, ZEROSAI X-AI. Examples of heat stroke prevention measures possible with ZEROSAI X-AI: - Cloud management of heat stroke information - Forecasting of the heat index (WBGT) tailored to the site with a mesh of 500m for up to 17 days ahead - Observation of the heat index (WBGT) in compliance with JIS standards using a black globe thermometer - Alerts for exceeding work standard values for the heat index (WBGT) via electronic bulletin boards, emails, and business chat tools like direct LINE WORKS We hope this will be useful at your sites as well.
