LigEPT Calcium Carbonate
EPT precipitated calcium carbonate (ligEPT calcium carbonate)
Formula: CaCO3
Molecular Weight: a hundred.09
Outside the house: White Powder
Mother nature:
White powder, odorless, tasteless, unchanging in air, insoluble in drinking water, 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 case of dilute acetic acid, dilute hydrochloric acid and dilute nitric acid, it is easy to boil and dissolve. Heat breaks down into calcium oXiHu (West Lake) Dis.de and carbon dioXiHu (West Lake) Dis.de.

LigEPT Calcium Carbonate Application

Broadly utilised in rubber, plastic, PVC pipes, profiles, paint, paper, paint, sealant, daily requirements, medicine, feed as filler and reinforcing agent. Not only can enhance the quantity, lessen the cost, far more EPTant is to enhance the processing functionality of the matrix, but also can play a part in strengthening, tensile, put on-resisting, tear resistance, improve luster, so calcium carbonate is not a EPT filler, but is identified as a purposeful filler.
LigEPT Calcium Carbonate with high whiteness and good fluidity is the largest filler for PVC pipes and profiles, which can increase the volume, stabilize the dimension, heat resistance, stage off and luster of the products, therefore lowering the value and achieving the objective of merchandise high quality.
Calcium rubber, with lower oil absorption price, excellent reinforcement influence, wear resistance and tear resistance and other attributes.
Particular calcium coating can boost adhesion, colour company oXiHu (West Lake) Dis.dation resistance, improve fill, decrease costs and other rewards.
