The Use of Calcium Carbonate in Polyolefins Offers

Calcium carbonate specific gravity is 2.7 g/cm3 compared to a general range of 0.90 to 0.96 g/cm3 for most polyolefins. This means 1 gram of calcium carbonate occupies approximately 1/3 the volume of 1 gram of polyolefin polymer. Outputs must be compared on a volume rather than weight basis . It also means that if product downgauging
