heavy calcium carbonate
CAS No.: 471-34-1
EINECS No.: 207-439-9
Chemical Formula: CaCO3
Synonyms: Carbonic acid calcium salt; calcite
Character:
Powdered inorganic fillers, high purity,big inert and difficult chemical reaction, thermal stability, will not decompose in the below 400 ℃, 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.
Classify:
According to different particle size is pided into: the ordinary heavy calcium powder, superfine heavy calcium carbonate, wet grinding super fine calcium carbonate, ultrafine surface modification of heavy calcium carbonate
Application:
At present, calcium carbonate has been widely used in paper, plastic, plastic film, chemical fiber, rubber, adhesives, sealants, daily chemical, cosmetics, building materials, coatings, paints, inks, putties and sealing wax, putty, a carpet layer of packaging,medicine, food (such as chewing gum, chocolate), feed
