Difference Between GCC and Modified Calcium Carbonate
重钙粉和改性碳酸钙有什么区别？
2026.05.21
Introduction
GCC and modified calcium carbonate are both CaCO3-based materials, but they are used for different processing requirements.
Key Points
GCC is commonly selected by particle size, whiteness and purity. Modified calcium carbonate adds surface treatment for better dispersion and compatibility.
Application Notes
Modified calcium carbonate is often considered in plastic masterbatch, PVC products, films and applications where processing behavior matters.
Quality Considerations
Customers should discuss surface treatment, dispersion, particle size, moisture and packaging before selecting a grade.

简介
重钙粉和改性碳酸钙都属于 CaCO3 基础材料，但适用的加工需求不同。
关键指标
重钙粉通常关注粒径、白度和纯度；改性碳酸钙通过表面处理提升分散性和相容性。
应用说明
改性碳酸钙常用于塑料母料、PVC 制品、薄膜以及对加工性能有要求的场景。
质量关注
客户应在选型前沟通表面处理、分散性、粒径、水分和包装方式。
