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.

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. Therefore, it is possible to compare the mi40 to a measurement unit which is similar to a capillary Rheometer.
