Although kaolin is found throughout the world, deposits with suitable whiteness, viscosity and other favorable characteristics are rare. Ironically, the best deposits are not located in China. The Unites States has highquality deposits in the Southeast. The mineral has been mined since colonial times in Georgia and South Carolina.
George Wypych, in PVC Degradation and Stabilization (Third Edition), 2015. FILLERS. Calcium carbonate is the most frequently used filler in PVC products. In PVC recycling, Braun 61 proposed to add 10% calcium carbonate to fortify a partially exhausted stabilizing system. This addition was expected to work by scavenging HCl evolved during thermal degradation.
