Hubercarb

Hubercarb is mainly pure calcium carbonate manufactured by hubergroup. There are four series of Hubercarb products available. Hubercarb® Q Series products include ultra-fine, fine, medium-fine and granular particle size calcium carbonates. Several of these products have been surface-modified to enhance end-use performance . Hubercarb® M Series Calcium Carbonate is mined from a uniform deposit of high calcium limestone in Marble Falls, Texas. Products include ultra-fine, fine and medium-fine sizes. Select products have been surface-modified to enhance end-use performance. Hubercarb® W Series Calcium Carbonate has a purity level of 99.3%, is mined from a world-class limestone deposit and processed in Quincy, Illinois. Products include ultra-fine and fine median particle sizes. Two of the W Series grades have been surface-modified to enhance end-use performance. The W Series products are ideal for applications that require high-filler loadings, low moisture content and silica content below detectable levels. The W Series is low in trace metals like iron, which can promote undesirable degradation in some polymer systems. The unique particle shape and particle size distribution lend the W Series products to low viscosity at high-filler loadings, improved surface-finish in molded parts, reduced part shrinkage and part breakage, while saving on expensive equipment repair costs. Hubercarb® G Series Calcium Carbonate is mined from a world-class deposit of high brightness marble in Marble Hill,Georgia. Products include ultra-fine, fine, medium-fine and granular particle sizes. Several of these products have been surface-modified to enhance end-use performance. The G Series products are ideal for applications that require high brightness or pure tints.
