Products Description
Muscovite paper is a sheet-like insulating material made from natural muscovite mica (Muscovite Mica) through high-temperature calcination, layered peeling, and papermaking. Its unique layered silicate structure provides excellent high-temperature resistance, insulation, and corrosion resistance. It is widely used in electrical equipment, aerospace, new energy, and other industries.
Muscovite paper Key data support:
Ingredient purity: SiO₂ content ≥ 45%, Al₂O₃ ≥ 30% (XRF test, in accordance with ASTM D3517 standard).
Thickness range: 0.03 mm to 1.0 mm (tolerance ± 0.005 mm).
Width: Customizable.
Length: Customizable.
Heat resistance level: Long-term use temperature of 600°C, with instantaneous temperature resistance up to 1000°C (IEC 60371 test).
Product advantages
| Advantages | Technical Explanation | Data Support |
|---|---|---|
| Ultra-high Insulation | The layered structure blocks the current path, with a volume resistivity > 1×10¹⁴Ω·cm. | The breakdown voltage strength is ≥ 25kV/mm (in accordance with IEC 60243 standard). |
| High Temperature Resistance | Muscovite has a melting point of 1270°C, and there is no decomposition or release of toxic gases at high temperatures. | The mass loss at 600°C is < 0.5% (as shown in the TGA test report). |
| Chemical Stability | Resistant to acids, alkalis, oils, and aging caused by ozone, and adaptable to harsh environments. | Passed the 48-hour immersion test in 5% HCl/NaOH (with a mass loss rate < 0.1%). |
| Flexible and Easy to Machine | Tensile strength ≥ 80MPa, and it can be stamped and wound into complex shapes. | No cracks were found in the 180° bending test (in accordance with ASTM D2176 standard). |
| Environmentally Friendly and Non-toxic | It is a natural inorganic material, free of asbestos and halogens, and complies with RoHS/REACH. | SGS certification report (heavy metals not detected). |
| Low Coefficient of Thermal Expansion | The coefficient of thermal expansion (CTE) is 5.4×10⁻⁶/K, which has a high degree of matching with metals and reduces thermal stress cracking. | Data from thermomechanical analysis (TMA) can be provided. |
Typical Application Scenarios:
New Energy Sector: Insulation and isolation of lithium battery modules (electrolyte corrosion resistance + flame retardancy).
Industrial Motors: Insulation of high-voltage motor windings (corona resistance life > 100,000 hours).
Household Appliances: Insulation of heating elements in electric ovens and microwave ovens (food-grade safety).
Railway Transportation: Insulation of interlayer in high-speed rail traction transformers (vibration resistance + moisture and heat resistance).
