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 h2o, 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 situation 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 Software

Commonly used in rubber, plastic, PVC pipes, profiles, paint, paper, paint, sealant, every day necessities, drugs, feed as filler and reinforcing agent. Not only can enhance the quantity, lessen the price, a lot more EPTant is to increase the processing overall performance of the matrix, but also can enjoy a role in strengthening, tensile, use-resisting, tear resistance, enhance luster, so calcium carbonate is not a EPT filler, but is acknowledged as a purposeful filler.
LigEPT Calcium Carbonate with high whiteness and excellent fluidity is the biggest filler for PVC pipes and profiles, which can boost the quantity, stabilize the size, heat resistance, amount off and luster of the products, as a result minimizing the price and reaching the function of merchandise good quality.
Calcium rubber, with lower oil absorption value, very good reinforcement impact, dress in resistance and tear resistance and other traits.
Unique calcium coating can improve adhesion, color company oXiHu (West Lake) Dis.dation resistance, boost fill, minimize charges and other benefits.
