LigEPT Calcium Carbonate
EPT precipitated calcium carbonate (ligEPT calcium carbonate)
Molecular Weight: 100.09
Outside: White Powder
White powder, odorless, tasteless, unchanging in air, insoluble in h2o, slightly soluble in drinking water conXiHu (West Lake) Dis.Hu (West Lake) Dis. ammonium salt or carbon dioXiHu (West Lake) Dis.de, insoluble in alcoholic beverages. In case of dilute acetic acid, dilute hydrochloric acid and dilute nitric acid, it is simple to boil and dissolve. Heat breaks down into calcium oXiHu (West Lake) Dis.de and carbon dioXiHu (West Lake) Dis.de.

LigEPT Calcium Carbonate Software
Broadly used in rubber, plastic, PVC pipes, profiles, paint, paper, paint, sealant, daily necessities, drugs, feed as filler and reinforcing agent. Not only can enhance the quantity, minimize the cost, much more EPTant is to increase the processing efficiency of the matrix, but also can perform a position in strengthening, tensile, wear-resisting, tear resistance, increase luster, so calcium carbonate is not a EPT filler, but is acknowledged as a purposeful filler.
LigEPT Calcium Carbonate with substantial whiteness and excellent fluidity is the greatest filler for PVC pipes and profiles, which can boost the quantity, stabilize the dimension, heat resistance, stage off and luster of the items, as a result decreasing the value and attaining the goal of item top quality.
Calcium rubber, with low oil absorption worth, excellent reinforcement effect, use resistance and tear resistance and other attributes.
Specific calcium coating can improve adhesion, coloration organization oXiHu (West Lake) Dis.dation resistance, boost fill, reduce charges and other rewards.
