Hubercarb® Product Recommendations:  

Ground calcium carbonate products are widely used in thermoplastic markets.  They can function as opacifier extenders, but finer grades also work as impact modifiers, glossing agents and cavitation agents as well as providing a cost-effective whiteness to the product.

Because of their morphology, the Hubercarb® W products are less abrasive than most other calcium carbonates.  The low iron content in the W Series grades leads to better heat and UV resistance in plastic compounds.
