Mflow applications
As your test volume increases, so does the need for a higher level of automation (when compared to the Cflow).
- The basic version of the Mflow extrusion plastometer is designed for MFR measurements according to method A.
- It features a modular design, and use of the piston displacement transducer expands the Mflow’s capabilities to include MVR determination according to method B, as well as automatic, field-dependent parameterization.
- These extrusion plastometers are typically used for quality assurance and incoming goods inspections.
Tests can be performed according to standards ISO 1133 (methods A and B), ASTM D1238 (methods A, B and C), ASTM D3364 and JIS K 7210.
The Mflow can be operated as a stand-alone instrument via a modern touch display, or with ZwickRoell’s testing software using a PC.

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.
