Product Description
 

Basic Information 

Chemical Name: Ultrafine Ground Calcium Carbonate

Molecular formula: CaCO₃

Property: White powder. Wide particle size distribution, high whiteness and low oil absorption value.

Chemical name: Activated natural calcium carbonate

Molecular formula: CaCO₃

Property: White fine powder, particle surface is covered by active substances, more easily dispersed in organic matter than ordinary heavy or light calcium carbonate without active treatment, better lipophilic, fully miscible in organic materials.

 

Chemical name: Calcium carbonate

Molecular formula: Caco₃

Gray-black powder, odorless, stable in air, not easily absorbent, hardly soluble in hydrated alcohol, slightly soluble in water containing ammonium salts and carbon dioxide, soluble in acidic aqueous solution.

Application

Ground calcium carbonate :Products are widely used in a variety of high-grade paint, paint, ink, paper and other industries.

Superfine active heavy calcium carbonate:.Ultra-fine activated ground calcium carbonate is an important filling material for plastics, rubber and coating industries. It can reduce cost, improve processing and improve quality performance. It can be used for thermoplastic plastics such as polyvinyl chloride and polyolefin, and for synthetic resin adhesives such as vinyl acetate to improve fluidity, shrinkage and curing speed.
Ground calcium carbonate:

Widely used in building materials, metallurgical refining, chemical synthesis, artificial floor tiles, soil improvement, as plastic, rubber filler to increase the volume of products, reduce production costs.
