Zwick's Mflow extrusion plastometer allows melt index values MFR and MVR to be determined quickly and conveniently.
The system features a modular design so that functions such as travel measurement can be retrofitted as and when required, while a weight selection unit provides operator safety and convenience.
Different weights are used in extrusion tests (MFR, MVR determination) depending on the polymer being tested.
The individual weights must then be positioned manually by the operator.
This is a laborious and potentially hazardous procedure, as a weight may fall and injure the operator.
A new development from Zwick has solved this problem.
Now available for the modular Mflow extrusion plastometer is an auxiliary unit that provides program-controlled positioning and removal of the test weight in use.
Manual selection is also possible by simply removing the selector and re-inserting it in the desired position.
The instrument contains test weights specified in ISO 1133 up to 21.6kg, arranged so as to eliminate the possibility of error.
Cleaning the instrument is no problem thanks to a swivelling unit.
The instrument can be controlled via integrated computer electronics or a PC as required.
The automatic parameter control (APC) ensures reliable measured values, even with untrained operators, said Zwick.
