Product Q&A

Q:What are the main types of calcium carbonate powder?

There are two primary types, distinguished by their production methods: Heavy Calcium Carbonate (GCC) and Precipitated Calcium Carbonate (PCC).

Q:What mesh size is required for different industries?

Generally, the more high-end the application, the higher the mesh size required, meaning finer particles are needed.

Q:What is the shelf life of calcium carbonate powder?

Typically 12 months under dry and ventilated conditions.

Q:How should calcium carbonate powder be stored?

Must be stored in a cool, dry, and well-ventilated warehouse. Keep away from moisture and rain. Do not store with acidic substances, as calcium carbonate decomposes upon contact with acid.

Q:What customization services are offered?

We provide comprehensive OEM and ODM services, customizing particle size distribution and surface treatments (such as stearic acid coating) to enhance compatibility with specific polymer matrices.
