Choosing the right mica grade affects product performance across paints, plastics, cosmetics and electrical components. This guide explains key mica grades, what technical specifications matter to formulators and buyers, and why sourcing from reliable Mica Suppliers in India speeds qualification and reduces waste. Vasundhara Micron combines in-house testing, sample packs and custom milling to simplify selection.
Cosmetic grade mica (high whiteness): fine, low-iron mica used for pearlescent effects in makeup and decorative coatings.
Electrical/insulation grade: high-purity sheet and flake mica with superior dielectric strength for capacitors and insulating tapes.
Filler and paint grade: micronized and ground mica with controlled particle size distribution for barrier properties, improved opacity and reduced cracking.
High-temperature/phlogopite grade: suited for friction materials and thermal applications where heat stability matters.
Exfoliated and coated mica: specialty products for flame retardancy, surface gloss or hydrophobic performance.
Chemical composition (XRF report), whiteness/L-value, moisture content, loss on ignition and particle size distribution are the minimum tests. For electrical uses insist on dielectric strength and volume resistivity. Surface treatment details (silane, stearate, coating thickness) matter when mica is used in polymers or cosmetics. Always request recent lab certificates and sample test results.
Start with the application requirement: optical effect, electrical insulation or filler performance. Match particle size and aspect ratio to the application — finer, spherical particles suit cosmetics while platy, high aspect-ratio particles offer better barrier in paints. Check supplier capabilities: can they mill to your mesh spec, provide coated mica, and supply consistent batches at scale? Also confirm packaging, MOQ, lead time and export documentation for international purchases.
Good suppliers support trial runs and help interpret test data. Ask for references in your industry — coatings, plastics, cosmetics, rubber and electrical component makers often share useful feedback. Reliable Mica Suppliers in India will provide technical notes showing typical performance (rheology impact in coatings, opacity change in pigments, or dielectric values for electrical parts). Confirm whether the supplier offers custom surface treatments or micronization to suit your formulation needs.
Price depends on grade, particle size, surface treatment and order quantity. Smaller trial orders cost more per kg; bulk orders reduce unit price and improve lead time predictability. Confirm freight terms and bonded warehouse options for exports.
Ask about traceability of raw mica and responsible mining practices. Suppliers who run regular audits, maintain supply chain records and reduce waste during milling will help meet corporate compliance and CSR targets.
