calcium carbonate powder for industrial fillers & coatings
Counterpart manufacturers and compounders require a high-purity calcium carbonate powder for filler, coating, and compounding applications. Sourced and prepared for industrial blending, the material is tailored for formulators needing consistent brightness and particle distribution. Typical procurement workflows include monthly bulk replenishment and specification verification before allocation. Request current MOQ and lead time to align volumes with production schedules.
Particle Size & Purity Specifications
- CaCO3 purity typically ≥95% by weight as a standard commercial grade (indicative).
- D50 particle size typically ~2–5 microns measured per ISO 13320 laser method.
- Moisture content typically ≤0.5% by weight under standard storage conditions.
- Bulk density typically 0.8–1.2 g/cm³ depending on grind and coating.
Procurement & Logistics Terms
- MOQ: Minimum order quantity varies by packaging format and grind; request current MOQ for your specific volume requirement.
- Lead Time: Typical dispatch timing depends on lot preparation and packaging; request current lead time for your order size.
- Supply Capacity: Produced in scheduled batch runs to support recurring orders and repeat replenishment for formulators.
- Packaging: Supplied in industrial jumbo bags or 25 kg kraft bags and palletized for bulk transport and handling.
- Quality Check: Batch-sample tested for CaCO3 purity and particle D50, reported on COA prior to shipment.
Industrial Applications & Processing
Paint and coatings formulators use calcium carbonate as an extender and pigment extender to control opacity and rheology. Plastics compounders add the powder to modify stiffness and reduce cost in PVC and thermoplastic blends, while paper and adhesive manufacturers use it to enhance brightness and bulk. In each application the particle size distribution and surface treatment affect dispersion and work-up; formulators should confirm D50 and surface treatment compatibility with their processing line. For scale production, buyers typically plan monthly replenishment cycles and require COA verification per scheduled runs.
Commercial Applications & Buyer Fit
Procurement teams sourcing filler-grade CaCO3 evaluate whiteness, LOI, and grind consistency when awarding supply contracts. Pricing tiers often depend on particle-size specification and packaging format. For recurring orders, contract pricing on request is available and export documentation is included for container-load shipments. Sample testing and COA review are standard steps prior to first bulk release to verify compatibility with buyer formulations.
Customization & Branding Options
- Specification Flexibility: Particle-size and surface-treatment options can be adjusted to meet application-specific dispersion and opacity requirements.
- Branding Support: Private-label bagging and OEM labeling are available for repeat customers with agreed specification and order bands.
- Packing Formats: Jumbo bags, palletized 25 kg bags, or customer-specific retail-ready packaging offered per agreement.
- Commercial Fit: Contract pricing and scheduled batch runs align to monthly or quarterly procurement planning for industrial buyers.
