Mflow - the Modular One
The basic version of the Mflow extrusion plastometers can be used to determine melt mass flow rates (MFR).
It features a modular design, and use of the piston displacement transducer expands the Mflow’s capabilities to include determination of melt volume flow rate (MVR), as well as automatic, field-dependent parameterization. These extrusion plastometers are typically used for quality assurance and incoming goods inspections.
The basic version of the Mflow extrusion plastometer is designed for MFR tests according to method A and can be expanded for MVR tests according to method B. Tests can be performed according to the following standards: Method A and B to ISO 1133, ASTM D1238, ASTM D3364, JIS K 7210.

An extrusion barrel must be chosen to suit the materials to be tested. Different plastics containing fluoride, such as PTFE and PFA, release hydrofluoric acid, which corrodes the material of the extrusion barrel. For these types of plastics, extrusion barrels made from a special type of steel alloy are used.
