• Composite Materials

"Composite mica" refers to mica that has been crushed and processed into a paper-like form, layered multiple times, and made into tape or sheet form. Due to its heat resistance and insulating properties, it is used as a material for mica heaters, insulation boards, and insulating plates. We can accommodate a wide range of products, from small quantities (machining and laser processing) to mass-produced items (stamped products). [Features] - Crushed mica processed into a paper-like form and layered multiple times into tape or sheet form - Used as a material for mica heaters, insulation boards, and insulating plates due to its heat resistance and insulating properties - Wide range of support from small quantities (machining and laser processing) to mass-produced items (stamped products) *For more details, please refer to the PDF document or feel free to contact us.

• Composite Materials

"Natural mica," known as "unmo" in Japanese, is a mineral primarily produced in India. With excellent electrical insulation and heat resistance properties, natural mica has been a representative product of our company since its founding and has long been used by our customers as one of the essential insulating materials in today's electrical industry. It is categorized into two types: "hard mica," which excels in electrical insulation, and "soft mica," which excels in heat resistance, allowing us to respond broadly to customer needs. 【Features】 ■ Excellent electrical insulation and heat resistance - Heat resistance temperature: Hard mica 600–800℃ / Soft mica 900–1000℃ ■ Excellent processability and dimensional stability ■ Excellent cost performance *For more details, please refer to the PDF document or feel free to contact us.
