Materials designed around the way you make things.
We work with industrial customers to align calcium carbonate grades, nano-modified options, formulation adjustments and supply requirements with the realities of their process.
Practical value across high-volume applications.
Our calcium carbonate powder solutions are developed for applications where processing consistency, dispersion and cost performance matter. The starting point is your industry, current formulation, production conditions and specification target. Where appropriate, nano-modified calcium carbonate and loading adjustments can be assessed to support a more efficient cost/performance balance.
PVC pipes & profiles
Modified GCC is selected around wall thickness, extrusion stability and target loading. Key discussion points include controlled fineness, moisture, dispersion and lower oil-absorption direction versus comparable untreated grades.
- 600–5000 mesh modified GCC available
- PL-1800 to PL-4000: D97 4–25 μm and oil absorption 21–29
- Formula and line validation required
Rubber & cable compounds
Surface treatment is reviewed for compatibility, dispersion, color and compound processing. The published product matrix includes dedicated wire-and-cable grade designations and active-grade options.
- Low-moisture and controlled-purity direction
- Surface-treated and high-activity options
- Match grade to polymer, color and line conditions
Paper processing
Paper and coating projects prioritize whiteness, brightness, particle-size distribution and uniformity. Fine, high-whiteness material directions are reviewed against the paper grade, coating formula and print target.
- Listed PL whiteness categories: 92–97+ by grade
- Listed PL blue brightness: ≥96 on specified grades
- Selection based on opacity, smoothness and printability target
Building materials
For mortar, boards, sealants and related construction systems, the balance is set around rheology, loading, moisture, cost and end-use performance. Grade selection starts with the customer’s binder and processing route.
- CaCO₃ ≥98% on published PL and nano series
- Controlled insoluble matter and iron content
- Modified surface system selected by application
Modified calcium carbonate, specified around the process.
HeBei Shoushi supplies modified ground calcium carbonate from 600 to 5000 mesh. The products are treated with application-oriented additives; compared with general untreated alternatives, the intended direction is lower oil absorption and improved processing compatibility. Final grade, oil-absorption result and loading level must be confirmed with the applicable test method and customer-side validation.
