Case study: influence of CaCO_3 surface treatments at a range of filler loadings

摘要

This study compares untreated calcium carbonate, and stearic acid treated calcium carbonate, with Solplus~R C800 treated calcium carbonate. The work used a very simple test system without antioxidant, and for this reason it was not necessary to add the peroxide normally required when using Solplus~R C800. Three series of compounds, each containing between 50 and 233 phr calcium carbonate, were made: a control series containing ground calcium carbonate (Carbital 110, Imerys). a series containing stearic acid treated calcium carbonate (Carbital 11 OS, Imerys). a series containing ground calcium carbonate (Carbital 1 10, Imerys), which was then treated with 0.6 percent Solplus~R C800.
