LigEPT Calcium Carbonate
EPT precipitated calcium carbonate (ligEPT calcium carbonate)
Method: CaCO3
Molecular Excess weight: 100.09
Outside: White Powder
Character:
White powder, odorless, tasteless, unchanging in air, insoluble in water, marginally soluble in h2o conXiHu (West Lake) Dis.Hu (West Lake) Dis. ammonium salt or carbon dioXiHu (West Lake) Dis.de, insoluble in alcohol. In circumstance of dilute acetic acid, dilute hydrochloric acid and dilute nitric acid, it is effortless to boil and dissolve. Heat breaks down into calcium oXiHu (West Lake) Dis.de and carbon dioXiHu (West Lake) Dis.de.

LigEPT Calcium Carbonate Application

Broadly used in rubber, plastic, PVC pipes, profiles, paint, paper, paint, sealant, day-to-day necessities, drugs, feed as filler and reinforcing agent. Not only can boost the quantity, lessen the expense, more EPTant is to improve the processing functionality of the matrix, but also can engage in a role in strengthening, tensile, dress in-resisting, tear resistance, increase luster, so calcium carbonate is not a EPT filler, but is identified as a practical filler.
LigEPT Calcium Carbonate with large whiteness and good fluidity is the greatest filler for PVC pipes and profiles, which can boost the volume, stabilize the measurement, warmth resistance, level off and luster of the goods, hence lowering the cost and attaining the function of product good quality.
Calcium rubber, with reduced oil absorption benefit, great reinforcement effect, put on resistance and tear resistance and other qualities.
Particular calcium coating can increase adhesion, color agency oXiHu (West Lake) Dis.dation resistance, improve fill, decrease charges and other rewards.
