The Melt Flow Index mi40 with automatic weight selection can carry out tests according to ISO 1133 and ASTM D 1238, procedures B, as well as ISO 1133 and ASTM D 1238 procedure C for the “Half Height / Half Diameter” standard. In addition, it runs tests according to procedure D for the FRR test (Flow Rate Ratio) and ASTM D 3364. The manual procedure A can be performed as well. The Tests can vary from one test loads (single load mode) to several test loads per barrel filling (multiple test load mode).
The new generation of melt flow index measurements comes up with the GOETTFERT mi40. Operators in quality control (QC) departments have experienced the advantage of further automized melt index measurements and the exact determination of MFR (Melt-Flow-Rate) as well as MVR (Melt-Volume-Rate) according to to ISO 1133 as well as ASTM D1238 (Procedure A-B-C-D). Due to force controlled compressing with up to 60kg the comparability is reaching a new standard. An additional advantage of the mi40 is the multi-load measurement with up to 8 different weights, which are operable in a descending and ascending mode. The automatic detection of the operating point illustrates an additional optimazation of the instrument. Therefore, it is possible to compare the mi40 to a measurement unit which is similar to a capillary rheometer.
For the mi40 are different options available. Furthermore, GOETTFERT provides add-ons, which extend the functionality of the device. The following add-ons are available:
