Product Snapshot: How We Solve Your Filler Problems
We are a Chinese manufacturer with over 3 years of experience in producing calcium carbonate powder. Many customers ask why they should choose our white calcite powder. The answer is simple: we provide real, verifiable data.
Have you experienced fillers that make your products brittle? Or unstable whiteness and high oil absorption during processing? Our factory addresses these issues at the source. We carefully select high-purity calcite ore and strictly control every production step. The data below represents our commitment to quality. Our white calcite powder is designed for performance.
Core Indicators (Real Test Data)
|
Core Indicator |
Our Actual Test Data |
Why This Matters |
|
Calcium Carbonate (CaCO₃) Content |
95.0% - 98.0% |
Higher purity means fewer impurities, resulting in more stable product performance |
|
Whiteness |
80% - 96% |
Higher whiteness reduces the need for titanium dioxide in paints and plastics. Batch variation is controlled within ±1.5 points |
|
Oil Absorption (DBP Absorption) |
20 - 35 ml/100g |
For plastics and rubber, we can achieve ≤28. Low oil absorption improves processing flow and reduces plasticizer cost |
|
Moisture Content |
≤0.3% - 0.5% |
Low moisture prevents agglomeration. Improves dispersion and reduces screen clogging in production |
|
Fe₂O₃ Content |
≤0.08% |
Low iron content prevents unwanted yellowing or reddening in light-colored products |
Production Strength and Case Experience
We have an R&D team of nine engineers focused on formula optimization and process improvement.
For example, for a PVC pipe customer, we reduced the 800-mesh sieve residue from 0.1% to below 0.05%, significantly improving pipe surface smoothness.
We have successfully served customers in the global building materials and chemical industries. They choose us because our quality system (ISO9001) and environmental system (ISO14001) have passed strict factory audits.
We also provide a clear quality commitment: all products come with a 3-month warranty after delivery. If any quality issue is caused by our production process, we will replace or refund the product. This commitment is clearly stated in our contract for white calcite powder.
