calcium carbonate(CaCO3) lump
Superfine ground calcium carbonate powder is the most important filler for the industrials of plastic, rubber, coating, paper making, building material, food, medicine and agricultural etc. It greatly cost down, also contribute to improve physical properties and there are more new trend for comprehensive applications in the new era.
