01
Ultraviolet Ray Shielding Function
Mica sheet-like crystals have natural UV shielding capability. The two-dimensional sheet-like structure stacked one by one forms an effective barrier layer, significantly enhancing the weather resistance and anti-aging properties of materials. Widely used in sun protection, weather-resistant coatings, and other fields.
02
2D Sheet-like Structure · Stacked One by One
Mica's unique two-dimensional sheet-like structure, with a diameter-to-thickness ratio ≥80, forms a dense barrier layer through stacking, effectively improving dimensional stability, flexural modulus, and barrier properties of plastics, providing excellent mechanical reinforcement.
03
Acid & Alkali Resistance · Good Electrical Insulation
Mica mineral has excellent chemical stability, acid resistance, alkali resistance, high temperature resistance, and excellent electrical insulation properties. It is an ideal functional filler for wires & cables, insulation materials, and other fields.
