Description

Mica CAS NO 12001-26-2 is a naturally occurring group of silicate minerals known for their unique layered structure, excellent thermal stability, and electrical insulating properties. This inorganic material is valued for its ability to enhance product performance through reinforcement, barrier protection, and aesthetic improvement. It is an essential industrial mineral for manufacturers in the plastics, coatings, cosmetics, construction, and electronics sectors seeking to improve mechanical strength, heat resistance, and surface finish.

Application

• Plastics & Polymer Composites: Used as a reinforcing filler to improve stiffness, dimensional stability, and heat deflection temperature in engineering plastics, automotive parts, and wire & cable insulation.
• Paints, Coatings & Inks: Acts as an extender pigment and barrier agent to enhance durability, corrosion resistance, weatherability, and reduce permeability in industrial and protective coatings.
• Cosmetics & Personal Care: Employed as a pearlescent pigment and filler to provide shimmer, improve skin adhesion, and control oil in foundations, eyeshadows, lipsticks, and nail polishes.
• Construction Materials: Serves as a filler and reinforcement in joint compounds, sealants, gypsum boards, and roofing materials to improve crack resistance and durability.
• Electronic Insulation: Utilized in mica sheets and tapes for its exceptional dielectric strength and thermal resistance in electrical equipment, heating elements, and insulating washers.
• Drilling Fluids: Functions as a lost circulation material (LCM) in oil and gas well drilling to seal fractures in the wellbore and control fluid loss.

Quality Control

Our mica products are sourced and processed under strict quality protocols to ensure batch-to-batch consistency and performance. Quality is verified through comprehensive testing of key parameters such as particle size distribution, brightness, chemical composition, and moisture content. We provide Certificates of Analysis (COA) with each shipment and can support compliance with relevant industry standards, including ISO 9001 quality management systems.

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 strong acids and moisture to prevent degradation of the mineral structure. Ensure the storage area is clean to avoid contamination.
