Effect of solid loading and aggregate size on the ...

The purpose of this study is to examine the effect of solid loading and aggregate size on the rheological behavior of PDMS (polydimethylsiloxane)/CC (calcium carbonate) suspensions. Mixtures containing 10 to 40 vol% of CC were prepared; the effect of shear rate and particle content on aggregate size and rheological properties was studied.

Melt strength of calcium carbonate filled polypropylene ...

This paper investigates the extensional rheology (through melt strength measurement) of calcium carbonate (CaCO 3) filled polypropylene (PP) melts. Different concentrations of CaCO 3 filled PP were produced by mixing two master batches of pure PP and 70 wt% CaCO 3 filled PP in required proportions in a counter‐rotating twin‐screw extruder.
