General description

Calcium carbonate is an inorganic compound that is commonly used as a solid base catalyst in some organic transformations. It is also used as an acid scavenger and stabilizing agent for acid-sensitive compounds. Additionally, CaCO3 is the most widely used additive in plastic and elastomeric applications due to its wide availability.

Features and Benefits

  • Increased efficiency – Eliminates time and effort of loosening hardened powders     
  • Safety – Eliminates tools of force used to break up clumps
  • Ecology – Reduces waste as it does not stick to the packaging
  • Economy – Faster preparation and solvation increase productivity and reduce costs     
  • Assured Quality – Excellent, expert-tested quality with no anti-caking agents      
  • Flexible volumes – Available from research amounts to scale-up quantities
