Determination of the melt mass-flow rate (MFR) of thermoplastics.

Test methods

The sample is subjected to melting and extrusion in a measuring cylinder through a specific longitude and diameter matrix under predefined temperature and load conditions. The extrusion speed result is expressed in g/10 min.
