- Commodity name: Mica board
Excellent Electrical Insulation Performance Provides dielectric strength of 12-35kV/mm, effectively isolating components in low-voltage to high-voltage (1kV-110kV) systems, preventing short circuits and arcing.
Wide Temperature Range Withstands continuous operating temperatures from 400°C to 1000°C (depending on type), maintaining stable performance in furnaces, engine compartments, and industrial ovens.
Robust and Durable High flexural strength (≥80MPa) can withstand bending or fracture under mechanical stress, making it suitable for heavy-duty applications such as motor slot insulation or mechanical spacers.
Flame and Chemical Resistant UL94 V-0 rated (non-flammable) and resistant to oil, weak acids, and moisture (water absorption ≤1.5%), ensuring a long lifespan in harsh industrial environments.
Precise Machinability Easy to cut, drill, or punch into custom shapes with tight tolerances (±0.1mm), adapting to complex designs in electrical and mechanical equipment.
Low Thermal Conductivity Reduces heat transfer between components, improving energy efficiency in heating systems and protecting sensitive components from overheating.
Specifications
Thickness 0.3mm-20mm, custom thicknesses available for special applications (e.g., thin insulation layer of 0.1mm).
Standard Dimensions 200×300mm, 300×500mm, 500×1000mm, 1000×2000mm; large sheets for industrial furnaces (maximum 3000×1500mm).
Density 1.6-2.3g/cm³ (depending on resin and mica type), balancing strength and weight for easy installation.
Resin Compatibility Silicone resin (for high temperatures up to 1000°C), epoxy resin (cost-effective, up to 600°C), phenolic resin (for low voltage, up to 400°C).
Surface Treatment Smooth (low friction) or textured (better adhesion in composite systems).
Product Types
White Mica Sheet Made from natural white mica, ideal for applications from 400°C-600°C. Offers good electrical insulation performance at a lower cost, used in home appliances (ovens, microwaves) and low-voltage motors.
Golden Mica Sheet Uses natural golden mica, suitable for environments from 600°C-800°C. Its magnesium-rich composition enhances heat resistance, used in industrial kilns, transformer cores, and high-temperature piping.
Synthetic Mica Sheet Made from laboratory-produced fluorophlogopite mica, withstanding temperatures up to 1000°C. Ultra-pure (no impurities) and extremely high insulation, used in aerospace, nuclear reactors, and high-precision electronics.
Composite Mica Sheet Laminated with glass cloth or ceramic fiber for enhanced strength, used in heavy machinery, power generation equipment, and high-voltage systems where structural integrity is critical.
Application Areas
Electrical Engineering Motor slot insulation, transformer insulation layers, and spacers in switchgear, ensuring the safe operation of high-voltage components.
Industrial Furnaces and Kilns Kiln linings, furnace doors, and heating chambers, protecting metal structures from extreme temperatures and reducing energy loss.
Automotive and Aerospace Engine compartment heat shields, exhaust system insulation, and battery pack separators, able to withstand vibration and high temperatures.
Home Appliance Manufacturing Base plates in toasters, hair dryers, and industrial heaters, isolating heating elements from the casing to prevent burns.
