Mica Sheet material is a high-performance insulating material widely used in electrical, thermal, and industrial applications. With the rapid development of power equipment, electronics, and high-temperature industries, Mica Sheets have become an essential solution for electrical insulation and thermal protection. As a professional manufacturer and supplier, YILONG provides reliable Mica Sheet materials designed to meet demanding industrial requirements.
Mica Sheets are thin laminated materials processed from natural mica minerals, which are silicate-based compounds mainly composed of silicon, oxygen, aluminum, magnesium, and iron. Mica features a unique crystalline layered structure, allowing it to be split into extremely thin sheets while maintaining excellent mechanical strength and stability.
This layered molecular structure gives Mica Sheets outstanding electrical insulation performance, high-temperature resistance, and good tensile and flexural strength, making them suitable for harsh operating environments.
Based on chemical composition and thermal performance, Mica Sheets are mainly classified into two types:
Muscovite Mica Sheets, commonly used in electrical and electronic insulation applications
Phlogopite Mica Sheets, preferred for high-temperature environments due to superior heat resistance
YILONG Mica Sheets are valued for the following core material characteristics:
Excellent electrical insulation, even under high temperature and high humidity conditions
Outstanding heat resistance, suitable for continuous thermal exposure
Good mechanical strength and dimensional stability
Strong chemical resistance to acids and alkalis
Reliable performance in long-term industrial use
Phlogopite Mica Sheets can withstand temperatures above 1000°C, while muscovite Mica Sheets typically tolerate temperatures up to approximately 500°C, depending on application conditions.
Electrical Insulation
Mica Sheets are widely used as electrical insulation materials in high-voltage equipment, transformers, motors, generators, and electrical appliances. They effectively prevent current leakage, enhance operational safety, and extend the service life of equipment.
High-Temperature Protection
Thanks to their excellent thermal stability, Mica Sheets are used as insulation components in heating elements, arc protection systems, furnaces, and metallurgical equipment. In steelmaking and other high-temperature industries, Mica Sheets help protect critical components from thermal damage.
Chemical and Corrosion Resistance Applications
Mica Sheets exhibit strong resistance to chemical corrosion, making them suitable for use in chemical processing environments. They protect equipment and structural components from acid and alkali exposure, reducing maintenance costs and improving operational reliability.
Thermal Management in Electronics
In addition to insulation, Mica Sheets provide controlled heat dissipation for electronic components. Their layered structure allows limited thermal conductivity while maintaining electrical insulation, making them suitable for power electronics, precision devices, and thermal interface applications.
Building and Fire-Resistant Materials
Mica Sheets are also applied in construction as fireproof and insulating materials. Their non-combustible nature and stability make them suitable for fire-resistant panels, insulation layers, and decorative building applications where safety and durability are critical.

Calcined Mica tape is a high-performance insulation material widely used in electrical systems where high temperature resistance, excellent dielectric strength, and long-term stability are required. Compared with unCalcined Mica paper, Calcined Mica undergoes a controlled dehydration process that improves its structure, resulting in stronger insulation performance and enhanced durability. YILONG specializes in producing Calcined Mica tapes tailored for motors, generators, medium and high-voltage applications, as well as high-temperature industrial equipment.
Mica tubes are widely recognized as a high-performance insulation solution in electrical and thermal systems. Thanks to their excellent dielectric strength, heat resistance, and dimensional flexibility, Mica tubes are essential components in motors, heating equipment, power devices, and advanced industrial systems. At YILONG, we manufacture Mica tubes engineered to meet diverse application requirements while ensuring long-term safety and reliability.
Selecting the right mica material is a critical decision in electrical insulation, thermal protection, and high-performance industrial applications. Among naturally occurring mica minerals, Muscovite Mica and Phlogopite Mica are the two most widely used due to their stable structure, excellent insulating properties, and proven performance in demanding environments. However, their different chemical compositions lead to distinct physical and electrical characteristics, making each type suitable for specific applications.
