Select your calcium carbonate grade based on the specific application. For food applications, choose food-grade calcium carbonate meeting FDA regulations, like FCC or USP grades. These ensure purity and safety for consumption.
Pharmaceutical applications demand extremely high purity, so look for pharmaceutical-grade calcium carbonate complying with standards like EP or BP. These grades undergo rigorous testing for contaminants.
Industrial uses, such as fillers in plastics or paper, usually require different specifications. Particle size distribution and whiteness are key factors here. Consider grades optimized for specific properties like flowability or opacity.
Agricultural applications often benefit from grades designed for soil amendment, containing specific levels of calcium and other nutrients. These differ from food or industrial grades in their composition and testing.
Always check the manufacturer’s specifications sheet for details on particle size, purity levels, and other relevant properties. Match these to your application’s requirements for optimal results. Don’t hesitate to contact the supplier for technical assistance if needed.
Key factors to compare include:
- Particle size distribution Whiteness and brightness Calcium carbonate content Specific surface area Contaminant levels
Careful grade selection ensures optimal performance and avoids unnecessary costs or quality issues.
