Materials engineered around your process.
Calcium carbonate powders, nano-modified grades and practical formulation support designed around consistent processing, dependable quality and long-term value.
From reliable supply to tailored performance.
Our portfolio brings together established calcium carbonate supply experience, controlled automated production, nano-modified material options and formulation support for industrial customers.
Ground Calcium Carbonate
High-quality GCC powders for broad industrial applications where stable whiteness, fineness and cost control matter.
Coated Calcium Carbonate
Surface-treated grades designed to support dispersion, compatibility and processing performance in polymer and rubber formulations.
Customized Powder Grades
Application-specific calcium carbonate grades with controlled particle size and properties to match your process requirements.
Functional Additives
Grinding aids and modification additives developed to improve calcium carbonate activation, dispersibility and compatibility.
Nano-Modified Calcium Carbonate
Surface-modified calcium carbonate options developed for improved dispersion and formulation efficiency. The material direction is evaluated against the customer’s performance target and production conditions.
Formulation & Process Support
We review the customer’s industry, current formulation and production conditions to discuss a practical powder, additive or loading adjustment. Cost-optimization opportunities are assessed through customer validation.
CONCEPTUAL VISUAL BASED ON SHOUSHI SAMPLE REFERENCESFrom sample screening
to practical process support.
Our additive development work considers activation, dispersion, compatibility and processability together with the intended calcium-carbonate application. We discuss powder, additive and loading direction around the customer’s existing formula and production conditions.
- Diverse additive and liquid-sample screening
- Powder–additive compatibility discussion
- Application-specific formulation review
- Customer-side validation under relevant production conditions
Key properties under control.
