Melt flow index

ZWICK/ROELL

The compact, easy-to-use Cflow extrusion plastometers have been designed as stand-alone instruments. They are specifically intended for MFR determination and are suitable for goods inwards checks.
Temperature control of the heating elements, heating chamber and barrel are exactly co-ordinated. The temperature is generated where it is applied, ensuring excellent temperature distribution over the whole barrel height from the outset.
Ergonomic design allows swift, effortless operation.
Cflow extrusion plastometers feature a generous standard package backed up by a comprehensive range of accessories.

The basic versions of the Mflow extrusion plastometers are used to determine the melt mass flow rate (MFR). Use of the displacement transucer expands their function to include determination of melt volume flow rate (MVR) and a unique automatic adaptive parameter configuration. Typical uses are in quality control and goods inwards.
Zwick's unique automatic adaptive parameter configuration is a 'world's first' system which automatically sets test parameters in accordance with material being tested to minimize measuring errors.
Special heating elements ensure precise temperature levels in the extrusion barrel.
Operator comfort and convenience thanks to the pneumatic weight-lifting system - weights can be raised and lowered automatically.

The Aflow extrusion plastometer (melt index tester) was developed especially for laboratories with high specimen throughput and therefore features robust design and convenient operation. The Aflow melt index tester supports all common worldwide standards, including ISO 1133 and ASTM D 1238. For the determination of melt mass flow rate (MFR) and melt volume flow rate (MVR) according to the methods A, B, C and D.
