Phlogopite mica has a significantly higher resistance to heat and a higher melting point, allowing it to maintain mechanical strength and electrical insulation in extreme high-temperature environments where muscovite would degrade.
Dry ground mica is produced by physical grinding to keep natural properties, while wet ground mica undergoes washing and purification, resulting in higher purity, better glossiness, and a larger radius-thickness ratio.
It is widely used in the production of refractory bricks, insulating boards, electrical gaskets, and heat-resistant components for the automotive and aviation industries.
Yes, it is used in heavy-duty anti-corrosive and fireproof coatings to impart a reflective finish and enhance the heat resistance and durability of the final coating.
We offer a wide range of specifications, including 4-6 mesh, 100 mesh, 325 mesh, 1000 mesh, and up to 3000 mesh to meet different industrial requirements.
Yes, our factories are ISO Certified and we hold 23 national patents for our processing technologies, ensuring consistent global quality standards.
