ones include inorganic materials such as calcium carbonate, dolomite, aluminum silica, titanium dioxide, and talc[6] while some of the organic materials used as filler are carbon black and natural fibers [78]. In flexible polyurethane s, the fillers promote an increase in density and resistance to compression.

Mar 06, 2014· Chelating calcium with such a substance is done in attempt to make the body use and process the calcium as well. Calcium citrate, for example, is simple calcium carbonate "chelated" with citric acid. The citric acid is considered food by the body, so calcium citrate is more easily absorbed into the body than calcium carbonate.
