Ground calcium carbonate is used in a wide variety of rubber applications as both an extender and de-tackifying agent.  In other applications, it can add stiffness or provide abrasion resistance. 

Because of their morphology, the Hubercarb® W products are less abrasive than most other calcium carbonates.
