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, a bit soluble in drinking water 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 effortless 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

Extensively utilised in rubber, plastic, PVC pipes, profiles, paint, paper, paint, sealant, everyday necessities, medicine, feed as filler and reinforcing agent. Not only can enhance the quantity, reduce the price, more EPTant is to improve the processing overall performance of the matrix, but also can play a position in strengthening, tensile, use-resisting, tear resistance, improve luster, so calcium carbonate is not a EPT filler, but is acknowledged as a purposeful filler.
LigEPT Calcium Carbonate with high whiteness and very good fluidity is the biggest filler for PVC pipes and profiles, which can increase the quantity, stabilize the dimension, warmth resistance, amount off and luster of the merchandise, as a result reducing the price and attaining the function of product top quality.
Calcium rubber, with reduced oil absorption worth, good reinforcement impact, wear resistance and tear resistance and other traits.
Particular calcium coating can increase adhesion, color agency oXiHu (West Lake) Dis.dation resistance, boost fill, minimize charges and other advantages.
