LigEPT Calcium Carbonate
EPT precipitated calcium carbonate (ligEPT calcium carbonate)
Molecular Excess weight: a hundred.09
Outdoors: White Powder
White powder, odorless, tasteless, unchanging in air, insoluble in water, a bit soluble in water conXiHu (West Lake) Dis.Hu (West Lake) Dis. ammonium salt or carbon dioXiHu (West Lake) Dis.de, insoluble in alcohol. In case of dilute acetic acid, dilute hydrochloric acid and dilute nitric acid, it is straightforward to boil and dissolve. Warmth 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, daily requirements, drugs, feed as filler and reinforcing agent. Not only can boost the volume, decrease the price, a lot more EPTant is to enhance the processing performance of the matrix, but also can engage in a role in strengthening, tensile, dress in-resisting, tear resistance, enhance luster, so calcium carbonate is not a EPT filler, but is identified as a practical filler.
LigEPT Calcium Carbonate with higher whiteness and good fluidity is the greatest filler for PVC pipes and profiles, which can enhance the volume, stabilize the dimension, warmth resistance, stage off and luster of the products, therefore lowering the value and reaching the function of merchandise top quality.
Calcium rubber, with minimal oil absorption worth, excellent reinforcement effect, put on resistance and tear resistance and other characteristics.
Unique calcium coating can improve adhesion, shade agency oXiHu (West Lake) Dis.dation resistance, improve fill, lessen expenses and other advantages.
