Ground calcium carbonate series 1
Ground calcium carbonate (400-2000 meshes)
Description
Features: It has stable chemical property, almost insoluble in water; has compact crystal structure, low impurity, smooth surface, even granularity, excellent processing properties, and low DOP oil absorption.
Use: It is widely used for the composite materials in paper making and plastic industries, such as various plastic pipes, section bars, plastic products, degradable plastic; tires, rubber products; paint primer, top coat, powder coating etc.
