Application areas:
Paper industry: Heavy calcium carbonate used in the paper industry has two main uses, one is as a filler, and the other is as a coating.
Rubber industry: Used in rubber, it can increase the volume of rubber, improve the processability of rubber, play a role of semi-reinforcement or reinforcement, and can adjust the hardness of rubber.
Plastic industry: The plastic industry is the largest consumer of heavy calcium carbonate. The refined heavy calcium powder can significantly improve the strength and mechanical properties of the plastic composite interface. The use of fine heavy calcium powder in plastic can not only reduce its manufacturing cost, but also improve and modify its performance.
Paints and coatings industry: Paints and coatings are also one of the main consumers of heavy calcium. They are generally used as fillers and extender pigments. The main application varieties are architectural coatings.
