▮Product use:
Heavy calcium carbonate is used in coatings, plastics, composite new calcium plastics, cables, papermaking, cosmetics, glass, medicine, paints, inks, cables, power insulation, food, textiles, feed, adhesives, sealants, asphalt, building materials It is used as filling material in products such as fireproof ceilings and artificial stone.
Advantages of superfine calcium carbonate:
In addition, the higher the oil absorption value of ultra-fine calcium carbonate for rubber, the better the wettability and reinforcement of calcium carbonate to rubber. Through application, it has been found that in different crystal forms of ultra-fine calcium, chain-like ultra-fine calcium carbonate It has the best reinforcement effect on rubber.
▮Packing and storage
Packing: 25kg paper-plastic compound bag and 500kg and 1000kg ton bags, can be packed according to customer requirements.
