LigEPT Calcium Carbonate
EPT precipitated calcium carbonate (ligEPT calcium carbonate)
Molecular Weight: a hundred.09
Outside: White Powder
White powder, odorless, tasteless, unchanging in air, insoluble in h2o, slightly soluble in 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 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
Widely utilised in rubber, plastic, PVC pipes, profiles, paint, paper, paint, sealant, every day necessities, medicine, feed as filler and reinforcing agent. Not only can increase the quantity, decrease the expense, more EPTant is to increase the processing functionality of the matrix, but also can perform a function in strengthening, tensile, dress in-resisting, tear resistance, enhance luster, so calcium carbonate is not a EPT filler, but is recognized as a useful filler.
LigEPT Calcium Carbonate with substantial whiteness and excellent fluidity is the premier filler for PVC pipes and profiles, which can boost the volume, stabilize the dimension, warmth resistance, stage off and luster of the items, as a result decreasing the price and reaching the objective of solution high quality.
Calcium rubber, with low oil absorption price, very good reinforcement influence, use resistance and tear resistance and other qualities.
Unique calcium coating can boost adhesion, colour agency oXiHu (West Lake) Dis.dation resistance, improve fill, reduce costs and other advantages.
