Automotive Industry
Natural micronized calcium carbonate (CaCO₃) as a functional filler for automotive plastics, rubber sealing, body fillers, primers and refinish applications. 4 grades AY 320, AY 540, AY 560 and AY 780 supplied to European OEMs and Tier 1/2 suppliers.
Calcium Carbonate in the Automotive Industry
Natural micronized calcium carbonate (CaCO₃) is used as a raw material and functional filler across multiple sub-sectors of the automotive industry. It is an indispensable production input in automotive plastic components, rubber seals and hoses, paint and primer formulations, body filler and adhesive sealants.
At Aydın Madencilik, we manufacture natural micronized calcium carbonate from high-purity calcite stone extracted at our own licensed quarry sites in Bursa Gemlik. Our automotive-grade products are supplied to OEM, Tier 1 and Tier 2 automotive suppliers across Turkey and Europe. Bursa being the heart of Turkey’s automotive manufacturing region reinforces our proximity to the European automotive supply chain and supports our just-in-time delivery capability for European OEMs and component suppliers.
Automotive Plastic Components
In automotive interior trim, bumper substrates and technical plastic components, calcium carbonate is used as a functional filler that improves mechanical strength, dimensional stability and surface quality of the part. Our AY 320 (20 µm) and AY 540 (40 µm) natural grades support the dimensional stability and impact performance required by OEM-grade automotive plastics — widely used by Tier 1 plastic compounders supplying interior trim, dashboard substrates and under-the-hood components to European car manufacturers.
Automotive Paint, Primer and Body Filler
In automotive refinish paint, primer and body filler formulations, calcium carbonate is the primary functional filler. Our coarser grades — AY 560 (60 µm) and AY 780 (80 µm) — deliver high filler-loading capacity and a smooth surface finish in automotive body filler (polyester putty) and primer formulations. These grades are widely used in the European automotive refinish and aftermarket coating segment.
Automotive Sealing, Hoses and Insulation
In automotive rubber sealing systems (EPDM door seals, weatherstrips), radiator and coolant hoses, engine mounts and acoustic insulation compounds, calcium carbonate reinforces the mechanical and thermal properties of the formulation. Our AY 320 (20 µm) grade is widely used in automotive rubber applications supplied to European Tier 1 and Tier 2 rubber compounders.
Aftermarket and Refinish Applications
Beyond OEM supply, our calcium carbonate grades are widely used in the automotive aftermarket — body filler, polyester putty, refinish primer, joint sealant and underbody coating. AY 560 and AY 780 provide the high filler loading and processability required for cost-effective aftermarket production.
