Applications
We match calcium carbonate grades to the demands of each downstream process.
Filler masterbatch
Coated active CaCO₃ for breathable-film and general filler masterbatch — hydrophobic compatibility and stable, high filler loading.
Buyer problem
High filler loading can cause poor dispersion, surface roughness and unstable processing.
How SokoChem helps
SC-9108C is reviewed for hydrophobic compatibility, filler dispersion and stable loading in PP/PE masterbatch.
Recommended grades
BOPP & breathable film
Fine, surface-treated grades for film masterbatch where dispersion and consistency are critical.
Buyer problem
Film producers watch for white spots, pinholes, roughness and lower finished-product yield.
How SokoChem helps
Active coated CaCO₃ can be tested for smoother film surface and more stable dispersion in BOPP/flexible packaging systems.
Recommended grades
Printing ink
Ultrafine uncoated grades for water- and solvent-based inks — dispersion, gloss, hiding power and reduced TiO₂ usage.
Buyer problem
Ink formulators need gloss, hiding power, anti-settling and pigment-cost control without coarse-particle defects.
How SokoChem helps
SC-9208 and SC-9508 are especially relevant where fine particle size and smoother printed coating appearance matter.
Sealant & adhesive
Coated active CaCO₃ for silicone/PU sealant, EVA hot-melt and adhesives — rheology control and stable filler loading.
Buyer problem
Sealant systems need compatibility, viscosity control, stable filler loading and clean appearance.
How SokoChem helps
SC-9108C is fatty-acid coated and hydrophobic, making it suitable for review in silicone, PU and hot-melt systems.
Recommended grades
Coatings & paint
Functional extender for water- and solvent-based coatings — whiteness, opacity and cost balance.
Buyer problem
Coatings need whiteness, opacity, gloss balance and a practical extender pigment strategy.
How SokoChem helps
Ultrafine grades are evaluated for hiding power support, surface smoothness and possible TiO₂ cost balance after testing.
Adhesives
Ultrafine and active grades for adhesive systems requiring compatibility and controlled rheology.
Buyer problem
Adhesive systems can be sensitive to viscosity, dispersion and compatibility with the binder.
How SokoChem helps
Uncoated ultrafine and active coated grades can be matched depending on resin system and rheology requirement.
PVC compound & pipe
Active grades for PVC compounding and profiles where treated fillers improve processing.
Buyer problem
PVC compound and pipe producers need processing stability, surface finish and formulation cost control.
How SokoChem helps
Active coated CaCO₃ supports polymer compatibility and smoother processing when filler loading is technically suitable.
