Measurement Methods for Flowability of Composite Highly Filled with Powder

doi:10.19491/j.issn.1001-9278.2021.02.015

Abstract

Abstract:

The flowability of composite highly filled with powder was measured at different temperatures using rod-falling method， melt index tester and capillary rheometer. Their comparison shows that three methods are all applicable in measuring such flowability. At the same time， comparing the three testing methods， it is found that the rod?falling method has the advantages of easy operation and wide range in testing materials.

Key words: rod-falling method, high-content-powder composite, melt index tester, capillary rheometer
