LigEPT Calcium Carbonate
EPT precipitated calcium carbonate (ligEPT calcium carbonate)
Formula: CaCO3
Molecular Weight: one hundred.09
Exterior: White Powder
Mother nature:
White powder, odorless, tasteless, unchanging in air, insoluble in water, somewhat soluble in h2o conXiHu (West Lake) Dis.Hu (West Lake) Dis. ammonium salt or carbon dioXiHu (West Lake) Dis.de, insoluble in alcohol. In situation of dilute acetic acid, dilute hydrochloric acid and dilute nitric acid, it is simple to boil and dissolve. Warmth breaks down into calcium oXiHu (West Lake) Dis.de and carbon dioXiHu (West Lake) Dis.de.

LigEPT Calcium Carbonate Application
Widely utilised in rubber, plastic, PVC pipes, profiles, paint, paper, paint, sealant, everyday necessities, drugs, feed as filler and reinforcing agent. Not only can enhance the quantity, lessen the cost, much more EPTant is to improve the processing overall performance of the matrix, but also can play a position in strengthening, tensile, dress in-resisting, tear resistance, increase luster, so calcium carbonate is not a EPT filler, but is known as a functional filler.
LigEPT Calcium Carbonate with large whiteness and good fluidity is the greatest filler for PVC pipes and profiles, which can improve the quantity, stabilize the size, warmth resistance, amount off and luster of the merchandise, as a result minimizing the expense and reaching the objective of merchandise top quality.
Calcium rubber, with reduced oil absorption benefit, very good reinforcement result, use resistance and tear resistance and other characteristics.
Specific calcium coating can boost adhesion, shade firm oXiHu (West Lake) Dis.dation resistance, boost fill, reduce fees and other advantages.
