LigEPT Calcium Carbonate
EPT precipitated calcium carbonate (ligEPT calcium carbonate)
System: CaCO3
Molecular Fat: a hundred.09
Outdoors: White Powder
Character:
White powder, odorless, tasteless, unchanging in air, insoluble in h2o, somewhat soluble in drinking water conXiHu (West Lake) Dis.Hu (West Lake) Dis. ammonium salt or carbon dioXiHu (West Lake) Dis.de, insoluble in liquor. In circumstance 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

Commonly used 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, lessen the value, far more EPTant is to enhance the processing efficiency of the matrix, but also can perform a part in strengthening, tensile, put on-resisting, tear resistance, improve luster, so calcium carbonate is not a EPT filler, but is recognized as a practical filler.
LigEPT Calcium Carbonate with high whiteness and great fluidity is the greatest filler for PVC pipes and profiles, which can enhance the volume, stabilize the dimensions, warmth resistance, degree off and luster of the items, thus minimizing the cost and attaining the function of merchandise good quality.
Calcium rubber, with minimal oil absorption price, excellent reinforcement influence, dress in resistance and tear resistance and other qualities.
Specific calcium coating can boost adhesion, coloration agency oXiHu (West Lake) Dis.dation resistance, improve fill, minimize costs and other rewards.
