Part 1: Product Overview
Phlogopite Mica is an important member of the mica family. Thanks to its excellent heat resistance and chemical stability, it is widely used in high-temperature environments with stringent safety requirements.
Our phlogopite mica products are made from high-quality natural phlogopite ore or synthetic phlogopite as raw materials, processed through precise splitting, crushing, grinding and classification. They feature high purity, strong heat resistance, large diameter-to-thickness ratio, and good surface luster. Phlogopite mica serves as an indispensable insulating barrier in both electrical and metallurgical & chemical industries.
Part 2: Core Advantages & Properties (Why Choose Us?)
Excellent Heat Resistance
The long-term service temperature of phlogopite mica can reach 800℃–1000℃, and the instantaneous temperature resistance can be as high as above 1200℃. Compared with muscovite, it adapts better to high-temperature working environments and maintains good mechanical strength after heating.
Outstanding Chemical Stability
It is resistant to strong acids, strong alkalis and corrosion, performing stably in harsh environments such as chemical engineering and electrolysis, with little decomposition or chemical reaction.
High Insulation & Dielectric Strength
With high insulation resistance, low dielectric loss and uniform breakdown voltage, it is the preferred material for insulating layers of high-pressure boilers and smelting furnace electric heating equipment.
Physical Processability & Elasticity
It features good cleavability and elasticity, and can be split into ultra-thin sheets. It ensures insulation while providing certain flexibility for easy processing.
Environmental Protection & Safety
Stable physical and chemical properties, non-toxic, non-radioactive, and produces no smoke or harmful gases when burned, complying with environmental and safety standards.
Part 3: Main Application Fields
Due to its unique heat resistance and insulation properties, phlogopite mica plays a key role in many industrial fields:
1. Electrical Insulation Industry (Core Application)
Mica Plates / Tapes
Used for manufacturing high-temperature resistant insulating tubes, fire-resistant cables, motor slot insulation and coil insulation.
Electric Heating Equipment
Used as support gaskets or insulating frameworks for heating elements in household appliances such as electric irons, hair dryers, electric ovens and microwave ovens.
Smelting Furnace Parts
Used for furnace body insulation and observation windows in metallurgical equipment including power frequency furnaces, medium frequency furnaces and electric arc furnaces.
2. Building Materials & Decoration
Stone-like Paints / Coatings
Phlogopite flakes or powder added to exterior wall coatings enhance the sparkling texture, improve weather resistance, water resistance and anti-cracking performance of the coating film.
Fireproof Materials
Processed into phlogopite plates as steel structure fireproof cladding materials, or used for fireproof door core boards.
Reinforcing filler: As a functional filler added to plastics or rubber, it significantly improves heat resistance, dimensional stability, insulation and anti-aging properties of the products.
Electrode auxiliary materials: Adding phlogopite to electrode coatings improves coating extrusion performance, enhances arc stability and prevents molten slag spattering.
With smooth surfaces, phlogopite flakes are high-quality substrates for pearlescent pigments. Coated with metal oxides such as titanium dioxide, they can be made into high-grade pigments with metallic luster or rainbow effects, used in automotive paints, cosmetic packaging and high-end inks.
