Nano calcium carbonate powder
Product Overview

Nano calcium carbonate powder is the name of Nanometer precipitated calcium carbonate, nano calcium carbonate powder is aslo can call super thin calcium carbonate or nano precipitated calcium carbonate ,the particle size between 1-100 nm, compare with the ordinary calcium carbonate product, because nano calcium carbonate powder product quality and the performance all had improved greatly, caused nano calcium carbonate powder top possible to play in the multitudinous application domain to the enhancement, the plasticzing role, from the surface change application product workability, usability and the outward appearance, might partically substitute for the carbon black, the titanium oxide powder. so nano calcium carbonate powder can reduce the product cost, therefore, nanometer calcium carbonate appearance, displays the wide spread service ability and big market demand, widely applies in domain and coating, plastic, rubber, adhesive, paper making, printing ink, cosmetics, and medicine.
