Description

Mica CAS NO 12251-00-2 is a naturally occurring group of silicate minerals known for their unique layered structure, excellent thermal stability, and electrical insulating properties. This material is valued for its ability to enhance durability, provide barrier protection, and improve the aesthetic and functional performance of a wide range of industrial products. It is an essential raw material for manufacturers in the coatings, plastics, construction, and cosmetics industries seeking to improve product quality and performance.

Application

• Paints & Coatings: Acts as a reinforcing filler and extender pigment to improve durability, weather resistance, and barrier properties while reducing cracking and checking.
• Plastics & Polymers: Used as a functional filler to enhance dimensional stability, increase stiffness, improve heat resistance, and provide a pearlescent effect.
• Construction Materials: Incorporated into joint compounds, sealants, and cementitious products to improve workability, crack resistance, and overall strength.
• Cosmetics & Personal Care: Provides a natural shimmer and pearlescent luster in makeup products like eyeshadows, lipsticks, and nail polishes.
• Electronics & Electrical: Serves as a high-temperature insulator in electrical equipment and as a substrate in electronic components due to its dielectric strength.
• Rubber Industry: Functions as an anti-blocking and release agent, improving processing and the surface properties of molded rubber goods.
• Welding Rod Coatings: Used in flux coatings for electrodes to stabilize the arc and contribute to slag formation.
• Drilling Fluids: Employed as a loss circulation material in oil and gas well drilling to seal porous formations.

Quality Control

Our mica products are sourced and processed under strict quality control protocols to ensure batch-to-batch consistency and meet the specific requirements of diverse industrial applications. Key parameters such as particle size distribution, brightness, chemical composition, and moisture content are rigorously tested. Certificates of Analysis (COA) are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from sources of moisture and incompatible materials. The product is hygroscopic (moisture-sensitive) and should be kept in its original packaging until use to prevent caking.
