Heavy calcium carbonate and Light calcium carbonate
Characteristic:
Powdered inorganic fillers, high purity,big inert and difficult chemical reaction, thermal stability, will not decompose in the below 400 °C, high whiteness, low oil absorption, low refractive index, soft, dry,without water of crystallization, hardness and low abrasion value, non-toxic, tasteless, odorless, good dispersion, etc.
Application:
Commonly used as fillers, are widely used in man-made tiles, rubber, plastic, paper, coating, paint, printing ink, cables, building supplies, food, pharmaceutical, textile, feed, toothpaste, and other daily-use chemical industry, as filler serve to increasethe volume of products, reduce production costs
