Calcium oxide, calcium hydroxide and calcium carbonate materials have long been recognized as both a performance additive and functional filler in rubber and plastic applications. Calcium oxide serves as a desiccant while calcium hydroxide serves as an accelerant in rubber applications. Ground and precipitated calcium carbonate (PCC) are widely used as fillers in plastic and rubber applications. PCC can also add functional properties in some applications.
Mississippi Lime’s PolyCal® O Calcium Oxide product family is used in rubber applications due to their specialized purity, reactivity and sizing. CalCarb® AC3, Magnum Fill® Powder and Magnum Gloss® Powder precipitated calcium carbonates provide a broad spectrum of sizing and physical attributes required of functional filler in plastic applications.
