Flexible Mica Insulation Sheet | Chengrui

The Flexible Mica insulation sheets also called soft mica boards, are engineered as superior insulating solutions designed to excel in demanding high-temperature environments. They combine natural mineral performance with advanced manufacturing for reliability and safety.

Material & Manufacturing

Base Material: Crafted from high-purity mica paper, ensuring consistent dielectric strength and thermal integrity.

Bonding Agent: Impregnated and bonded with a high-performance, heat-resistant silicone resin.

Production Process: The composite undergoes a controlled process of high-temperature baking and pressing, resulting in a uniform, durable, yet flexible plate material.

Characteristics of Mica insulation sheet:

1. Outstanding Electrical Insulation: Provides excellent dielectric protection in various electrical applications.

2. Exceptional Thermal Endurance: Engineered for continuous, long-term service at temperatures ranging from 500°C to 700°C.

3. Mechanical Flexibility: Retains pliability for easy forming, cutting, and wrapping around complex components.

4. High Stability: Resists degradation, aging, and delamination under thermal cycling.

Advantages of Electrical insulation mica sheet:

• Reliable Performance: Offers consistent insulation under extreme heat, enhancing equipment safety and longevity.

• Versatile Form Factor: The flexible nature allows for easy installation on curved surfaces and heating elements.

• Durability: Withstands thermal shock and physical stress, reducing maintenance needs and downtime.

Flexible insulation mica sheet is suitable for electric heating devices requiring winding, such as hair dryers, electric soldering irons, microwave ovens, heating rods, and hair curlers. They are also used for high-temperature insulation in various industrial furnaces, including power frequency furnaces, medium frequency furnaces, and electric arc furnaces in industries such as steel and metallurgy. Furthermore, they serve as a replacement for asbestos and are widely applied in automotive, shipbuilding, petroleum, metallurgy, and other sectors.
