Mica Powder-Versatile Functional Filler Empowering Coatings, Rubber and Insulationresistant Industrial Fields

Mica powder is layered silicate mineral material, including dry-ground mica powder, wet-ground mica powder, natural sericite, synthetic mica, golden mica and black mica. Produced through ore crushing, grinding and classifying processing, it features sheet-shaped structure, excellent electrical insulation, heat resistance, anti-corrosion, anti-oxidation and weather resistance. Products cover mesh sizes ranging from 20 mesh to 2500 mesh with adjustable whiteness. As global manufacturing pursues high durability and cost-effective raw materials, mica powder has become an indispensable reinforcing filler widely used in coatings, rubber products, electrical insulation materials, welding materials and anti-corrosion projects.

In the coating and paint industry, different grades of mica powder deliver differentiated performance upgrades. Cost-effective dry-ground mica powder and sericite serve as basic fillers for general industrial coatings and anti-rust paint, improving coating hardness and anti-aging performance. High-quality wet-ground mica powder with fine silky luster and good suspension property is ideal for high-end architectural paint, automotive topcoat and sealant. Its high aspect-ratio sheet structure forms compact barrier layers inside paint film, slowing water vapor and corrosive medium penetration, enhancing weather resistance and anti-corrosion capacity of coating surface. Synthetic mica with high transparency can be added into high-grade varnish to improve surface gloss. Golden mica brings metallic luster effect for decorative paint, while acid-resistant black mica fits heavy-duty anti-corrosion coating working under harsh high-temperature environment.

For rubber and plastic manufacturing, mica powder acts as reinforcing functional additive. Dry-ground mica and sericite are widely adopted in general rubber, plastic and rubber-plastic composite products. It elevates material heat-resistant performance, dimensional stability and anti-oxidation property, reducing raw-material cost by partial replacement of high-price fillers. Wet-ground mica powder with fine lamellar structure is applied in high-grade sealing strips and grease, improving sealing performance and wear resistance of finished parts. Golden mica and black mica can be blended into plastic granules to realize special metallic appearance and strengthen chemical corrosion resistance for finished plastic goods.

In electrical insulation and welding material sectors, mica powder shows outstanding high-temperature insulation performance. Dry-ground mica powder is core raw material for electrical insulation strips, special welding rods and mica boards, blocking electric conduction and enduring long-term high-temperature working conditions. High-purity synthetic mica free of mineral impurities is well-suited for special welding material production, maintaining stable insulation property under extreme temperature. Black mica with excellent acid-alkali resistance is selected for electrical component filler used in severe working environment.
