Calcium carbonate from China
Ultrafine & active calcium carbonate, engineered for performance
We supply surface-treated and ultrafine CaCO₃ grades for printing ink, masterbatch, BOPP film, sealant, adhesive and coating producers. Better dispersion, stable filler loading and consistent whiteness — not just a low-cost filler.
Industrial selection path
A clearer path from material fit to repeat shipment
Premium industrial websites make the evaluation path visible: application, proof documents and export execution. SokoChem presents calcium carbonate the same way, so engineers and buyers can move faster.
Application
Match the grade to the process
Start from ink, masterbatch, film, sealant, adhesive or coating needs before comparing particle size and surface treatment.
Proof
Validate with TDS, COA and MSDS
Every serious inquiry is tied to technical documents and batch evidence, not a generic filler description.
Export
Move from sample to FOB/CIF quote
Share your target port, consumption and quality requirements; the export team follows up manually after Bark notification.
Why formulators choose SokoChem
Engineered dispersion
Ultrafine particle size and surface treatment give cleaner dispersion, anti-settling behavior and stable rheology in demanding systems.
Consistent quality
Whiteness above 96 and tight particle-size control, batch after batch, backed by COA on every shipment.
Application-matched grades
We recommend a grade based on your application, particle size, whiteness and coating needs — not a one-size-fits-all powder.
Export-ready
FOB and CIF quotations, full export documentation, and shipping experience across Asia, Africa and the Middle East.
Two engineered product lines
Matched to ink/adhesive formulation and to plastics/sealant processing.
Ultrafine grades for ink & adhesive
SC-9108 / SC-9208 / SC-9508 — sub-micron uncoated CaCO₃ for printing ink, adhesives and coatings. Improves dispersion, gloss, hiding power and anti-settling, and can reduce part of TiO₂ usage.
View all productsActive grades for plastics & sealant
SC-9108C — fatty-acid coated, hydrophobic, activation above 98%. Designed for filler masterbatch, BOPP film, silicone/PU sealant, hot-melt adhesive and PVC compounding.
View all productsBuilt for your application
From masterbatch lines to ink kitchens — we match the grade to the job.
Filler masterbatch
Coated active CaCO₃ for breathable-film and general filler masterbatch — hydrophobic compatibility and stable, high filler loading.
BOPP & breathable film
Fine, surface-treated grades for film masterbatch where dispersion and consistency are critical.
Printing ink
Ultrafine uncoated grades for water- and solvent-based inks — dispersion, gloss, hiding power and reduced TiO₂ usage.
Sealant & adhesive
Coated active CaCO₃ for silicone/PU sealant, EVA hot-melt and adhesives — rheology control and stable filler loading.
Coatings & paint
Functional extender for water- and solvent-based coatings — whiteness, opacity and cost balance.
Adhesives
Ultrafine and active grades for adhesive systems requiring compatibility and controlled rheology.
PVC compound & pipe
Active grades for PVC compounding and profiles where treated fillers improve processing.
