Quali-Fi 6000 Melt Flow Indexer Series can be used for testing MFR and MVR of polycarbonate, fluoroplastics, as well as polyethylene, polypropylene, ABS, POM, etc and is related to the melted material viscosity. It enables the operator to estimate the mean molecular weight and at the same time gives an indication of melt flow ability through the die.
Both Melt flow rate and Melt volume rate can be determined with Quali Fi 6000 Series through a calibrated die under the effect of a pre-determined force, at constant temperature and for the total time of 10 minutes. The instrument is equipped with special features like movable oven for easy cleaning and inspection; Automatic application of selected load; Piston displacement monitored by encoder; Software for result acquisition, storing and exporting whenever necessary.
The instrument with built in weights has the provision to select the weight automatically by a simple touch of the operator on the screen. In case of multi weight testing the choice can be for incremental or decremental testing. No manual weight handling is required.
The instrument is with a wide color touch screen for a simple and fast input of the test parameter, visualization of test execution and final results. The results can be connected to a PC through a RS232 port for direct acquisition of the test parameters and test results which can be saved or exported with the help of the software.
The multi weight testing allows for calculation of the following results to indicate the rheological properties of material:
The LMFI-5000 series melt flow indexers are designed to meet or exceed the ASTM D1238 specifications as well as international standards. They provide an accurate, cost- effective means of monitoring material flow characteristics consistency.
MFI-2000 Series Melt Flow Indexers are affordable benchtop instruments that measure the melt mass-flow rate (MFR) and melt volume flow rate (MVR) of a wide range of thermoplastic raw materials (granulate). The tester conforms to all International Melt Flow Resistance standards, including ISO1133, ASTM D1238. Any temperature within 100oC - 450oC can be accurately controlled.
