Abstract

The effect of synthetic sodium aluminum silicate (SSAS) on the mechanical, physical, electrical, optical, and rheological properties of two different grades of polypropylene (PP) homopolymer with melt flow indexes (MFIs) of 3 and 11 was studied. Incorporation of SSAS improved the flexural strength and modulus of PP. At a given loading of SSAS, the mechanical properties of MFI 3 PP were better than those of MFI 11 PP. The presence of significant slip at the wall was observed for SSAS filled PP. The addition of a fluoropolymeric processing aid increased the slip effect further. Β© 2001 John Wiley & Sons, Inc.
