Melting index tester is an instrument to measure the flow performance of thermoplastics at high temperatures according to the test methods of GB3682-2000 and ISO1133. It is controlled by a microcomputer (single chip microcomputer) and has a Chinese operation interface to automatically test the results. It is applicable to the measurement of the melt flow rate of polyethylene (PE), polypropylene (PP), polyoxymethylene (POM), polystyrene (PS), ABS plastics, polycarbonate (PC), etc. at high temperatures.
The main technical parameters are as follows:
