Hubercarb® Product Recommendations:
- W4, W3 and W3N (Extremely low level of crystalline silica from Quincy, Illinois)
- G325, G8, G6, G3 and G35 (High brightness ground calcium carbonate from Marble Hill, Georgia)
- Q325, Q6, Q4 and Q3 (Ground calcium carbonate from Quincy)
- M300, M4 and M3 (Ground calcium carbonate from Marble Falls, Texas)
Ground 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. It is used for viscosity control, to limit shrinkage and as a coefficient of thermal expansion.
Because of their morphology, the Hubercarb® W products are less abrasive than most other calcium carbonates.
