PP Calcium Carbonate Compound
Calcium carbonate master batch for transparent HDPE film available now. Adding by 510%, transparency becomes better in some cases; adding by 1030%, transparency is still good enough. It's also good for LDPE film, HDPE pipe and PP sheet, which are transparent, but not very transparent.

Calcium Carbonate Filler
Precipitated calcium carbonate (PCC) can be produced by "calcining" limestone at very high temperature to drive off CO2, "slaking" the resulting lime by addition of water, and then treating the resulting "milk of lime" suspension with CO2 gas under highly controlled conditions of temperature, pH, and ionic composition. The process results in calcite particles.
