The Huber industrial calcium carbonate products are used in thermoset composite applications. They function as an extender in glass reinforced polyester applications such as sheet moulding compound (SMC) and bulk moulding compound (BMC).

The increase is effective 18 November 2013, or as current contracts allow. Prices will increase by an average of 4-9% depending on product grade and packaging.

Huber cites the impact of rising costs for materials, packaging, freight, logistics and regulatory compliance as reasons for the increase.
