LigEPT Calcium Carbonate
EPT precipitated calcium carbonate (ligEPT calcium carbonate)
Formula: CaCO3
Molecular Weight: a hundred.09
Outside: White Powder
Nature:
White powder, odorless, tasteless, unchanging in air, insoluble in drinking water, a bit soluble in h2o conXiHu (West Lake) Dis.Hu (West Lake) Dis. ammonium salt or carbon dioXiHu (West Lake) Dis.de, insoluble in liquor. In situation of dilute acetic acid, dilute hydrochloric acid and dilute nitric acid, it is easy 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

Broadly used in rubber, plastic, PVC pipes, profiles, paint, paper, paint, sealant, daily necessities, medication, feed as filler and reinforcing agent. Not only can improve the volume, lessen the price, much more EPTant is to enhance the processing efficiency of the matrix, but also can play a function in strengthening, tensile, put on-resisting, tear resistance, boost luster, so calcium carbonate is not a EPT filler, but is known as a purposeful filler.
LigEPT Calcium Carbonate with large whiteness and good fluidity is the largest filler for PVC pipes and profiles, which can boost the quantity, stabilize the measurement, heat resistance, amount off and luster of the goods, therefore minimizing the cost and reaching the goal of solution high quality.
Calcium rubber, with low oil absorption benefit, very good reinforcement influence, use resistance and tear resistance and other characteristics.
Unique calcium coating can boost adhesion, coloration agency oXiHu (West Lake) Dis.dation resistance, enhance fill, reduce charges and other rewards.
