Mica Board: High-Temperature Safety Barrier for Electrical Equipment
Distinct Product Categories | Tailored for All Harsh Working Conditions
Muscovite Mica Board | Cost-effective General Grade
Stable insulation performance and excellent toughness with reliable heat resistance. Widely used for conventional insulation in general motors, low-voltage electrical appliances and household heating appliances.
Phlogopite Mica Board | Industrial High-temperature Grade
Greatly upgraded high-temperature resistance with outstanding aging and burning resistance. Ideal for medium and high-temperature harsh environments such as industrial electric furnaces, metallurgical equipment and high-temperature kilns.
Synthetic Mica Board | High-end Precision Grade
High purity with few impurities and higher temperature resistance limit. Its physical and chemical properties far exceed natural mica boards, widely applied in high-demand fields including new energy, high-end electrical and precision electronics.
Composite Mica Board | High-strength Reinforced Grade
Reinforced with glass fiber cloth for structural enhancement. Remarkably improved bending and tearing resistance, suitable for heavy-duty electrical equipment with long-term vibration and load-bearing requirements.

Core Performance | Four Major Advantages Build Solid Safety Barriers
Mica board acts as the reliable safety guardian for electrical equipment, thanks to four irreplaceable core performance attributes that solve the industry pain points of high temperature, electric leakage and material aging.
🔌 Superior Insulation, Isolate Power Risks
Mica board is a premium inorganic insulating medium with high dielectric strength and is not easily broken down under high voltage. It effectively isolates circuits and eliminates hidden dangers such as electric leakage, short circuits and electric arcs. It serves as the core material for phase separation, gaskets and partition plates inside high and low-voltage electrical equipment.
🔥 High Temperature & Burning Resistance, Withstand Sustained Heat
Ordinary plastic insulation parts fail below 200℃ and tend to soften and deform easily. In contrast, mica board can withstand high temperatures of hundreds of degrees Celsius long-term. It does not crack, soften or decompose under heat with excellent thermal stability, reliably handling safety risks caused by continuous equipment heat generation.
⚙️ Stable Mechanical Performance & High Processing Flexibility
With compact texture and delamination resistance, mica board features outstanding bending and vibration resistance, suitable for equipment operating under long-term vibration conditions. It can be cut, drilled and stamped into custom special-shaped gaskets, partitions and bushings to match various equipment structural designs.
🌿 Eco-friendly & Weather Resistant, Adapt to Harsh Environments
It meets high flame retardant grades: non-combustible on exposure to fire and self-extinguishing after leaving flame, releasing no harmful gas at high temperature. It resists moisture, oil contamination and slight corrosion. Halogen-free and asbestos-free, it complies with RoHS standards for long-term service in dusty, humid and mildly corrosive working conditions.


Full-range Application | Invisible Protection Everywhere
A seemingly thin mica board has covered key sectors across all industries, silently safeguarding the safe operation of equipment.
