Plastics and Rubber

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 calcium carbonate is widely used as fillers in plastic and rubber 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 provides a broad spectrum of sizing and physical attributes required of functional filler in plastic applications.
