Our Products

Aydın Madencilik’s product range covers micronized calcium carbonate (CaCO₃), limestone and calcite stone for the varied needs of industry. Our products are offered in a 1–100 µm particle size range (d50 3–15 µm, d97 10–45 µm), with 98%+ CaCO₃ purity and ISO 2470-1 90–97 brightness, in both natural and stearic-acid coated grades.

Each product is manufactured with fineness and surface properties optimized for its application, and is used as a filler and coating agent in paint, plastics, paper, rubber and construction chemicals. Technical values vary by product and batch; exact specifications are stated in the certificate of analysis (CoA). For the right grade and fineness for your application, you can request a sample and technical advice from our team.

How to Choose the Right Grade

The right calcite grade depends on your application. Key parameters to assess:

• Particle size (d50/d97): fineness, surface quality and loading.
• Brightness (ISO): critical for colour cleanliness and opacity.
• Surface: natural or stearic-acid coated (dispersion, moisture resistance).
• Purity (CaCO₃ %): resin demand and final performance.
• Packaging: bags, big-bag or bulk — by order and logistics.
