1.Calcium carbonate is utilized in vinyl flooring applications as a weighting and whiting agent, a cost-reducer or as a stiffener. 2.Calcium carbonate is used in a wide variety of rubber applications as both an extender and detacktifying agent. In other calcium carbonate rubber applications, it can add stiffness or provide abrasion resistance. 3.Calcium carbonate is widely used in thermoset applications. It is a key extender in fiberglass reinforced polyester applications such as Sheet Molding Compound (SMC) and Bulk Molding Compound (BMC) where it functions as a cost-effective extender with no adverse effects on processing or final physical properties. 4.Calcium carbonate is used for viscosity control, to limit shrinkage and as a coefficient of thermal expansion. 5.Calcium carbonate is commonly used in a number of paint and coating applications. It is used as an extender, an agent to either reduce or enhance gloss, an extender / spacer for titanium dioxide, a rheology modifier and as a paint and coating additive to densify the product.
