The Melt Flow Index intrument MI-3 enables to measure the melt-flow-rate (MFR) and the melt-volume-rate (MVR) with a semi-automatic instrument. The MFR is the mass of polymer in grams flowing in 10 minutes through a capillary of a specific diameter and length and with a specific pressure applied by means of weights for prescribed temperatures. The method is given in ASTM D1238 and ISO 1133. This unique melt index instrument ca…
