Product Description
Mica Powder Fine Grinding
Insulating Filler for Plastics & Coatings, Cosmetic Pearlescent Pigment
Mica powder is produced through mechanical crushing, grinding, and classification of natural mica minerals (primarily muscovite and phlogopite), resulting in a lamellar silicate powder. This product retains mica's unique layered crystal structure, imparting properties such as excellent electrical insulation, high-temperature resistance, chemical stability, high aspect ratio, good covering power, and pearlescent effect. These characteristics elevate it beyond a mere filler, making it a functional mineral additive capable of significantly enhancing the physical and chemical properties of matrix materials.
Core Applications
Polymer Composites Reinforcement
Mica powder serves as a reinforcement and modification expert in polymer composites:
- Engineering Plastics and Rubber Reinforcement: In materials like nylon (PA), polypropylene (PP), and polyesters (PBT/PET), the lamellar structure effectively impedes gas and moisture permeation, improves dimensional stability, reduces warpage, and enhances rigidity, heat resistance, and insulation.
- Functional Rubber Filler: Improves gas barrier properties, electrical insulation, heat aging resistance, and mechanical strength of rubber products.
Coatings and Inks Industry
Mica powder functions as a multi-functional effect agent:
- Anti-Corrosion and Fire-Resistant Coatings: Mica flakes align parallel and overlap within the coating film, forming a dense physical barrier that significantly extends the diffusion path for corrosive media (water, oxygen, ions).
- Decorative and Effect Coatings: Leverages high refractive index and plate-like structure to create soft pearlescent sheen in automotive paints, furniture finishes, and printing inks.
Cosmetics and Personal Care
Cosmetic-grade mica powder (strictly compliant with regulations) provides safe luster in color cosmetics:
- Pearlescent Effect and Skin Feel Improvement: Essential raw material for eyeshadow, blush, face powder, lipstick, and nail polish due to non-toxicity, softness, and natural luster.
Building Materials and Electrical Applications
Mica powder provides stabilizing foundation across multiple industries:
- Building Materials: Enhances fire resistance, durability, and crack resistance in mica cement boards, fireproof boards, and wall joint compounds.
- Electrical Insulation Materials: Base material for manufacturing electrical insulating products like mica paper, mica plates, and mica tapes.
- Welding Consumables: Serves as an additive in electrode coatings for slag formation and arc stabilization.
Product Specifications
Our mica powder is graded based on parameters including:
- Particle size (mesh)
- Aspect ratio
- Whiteness
- Purity (content of impurities like iron)
- Surface treatment (e.g., with silane coupling agents)
We supply mica powder produced via dry or wet grinding processes. Our products are characterized by well-preserved lamellar structure, narrow particle size distribution, low impurity content, and stable chemical properties.
Custom Solutions
We provide customized mica powder solutions for plastic compounders, paint companies, cosmetic manufacturers, building material producers, and electrical equipment factories. Based on our clients' matrix materials and application processes, we recommend the most suitable grade and surface treatment option to assist in developing high-performance, high-value-added products.
