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 can carry out a single weight test according to ISO 1133 and ASTM D1238, procedures B, as well as ISO 1133 and ASTM D1238 Procedure C for the "Half Height / Half Diameter" standard.
The MI-3 is equipped with a weight cartridge, to enable the operator an opportunity to choose the measuring weight manual. The instrument enables operators in quality control (QC) and incoming goods inspection to conduct single measurements while meeting highest quality standards according to ISO 1133 as well as ASTM D1238 (Procedure A-B-C). The high resolution position sensor with an automatic selection of the resolution allows a repeatable, reliable determination of MFR and MVR. Besides the standardized measurement processes (ASTM and ISO) GOETTFERT also provides add-ons, which are postitively contributing to the total value of the instrument.
The MI-3 comes with different options. Furthermore, GOETTFERT also provides add-ons, which are extending the functionality of the device. The following add-ons are available:
