viscosity  

The measurement of rheological functions in a wide range of shear rates for polymers is the focus of our capillary rheometers. A multitude of options allows simulating important manufacturing processes of polymers, elastomers and thermosets.

 

Melt IndexThe mass of polymer in grams flowing in 10 minutes through a capillary of specific diameter and length by a pressure applied by means of weights for prescribed temperatures. Method is given in ASTM D1238 and ISO 1133. >>Melt Indexer testing - a complete product range from simple manual equipment to a fully automatic "MFR-Robot".

The mi2 Melt Indexer series can carry out a single weight test according to ISO 1133 and ASTM D1238, procedures B, as well as ISO 1133 and ASTM1238 procedure C for the "Half-Height/Half-Diameter" standard and ASTM D 3364. Also the manual procedure A is possible to perform.
This is the basic device of the mi2-series.

The mi2.3 machine is equipped with a weight selection and electrical weight lifting unit. The weights remain always inside the device.
The Melt Indexer Model MI-3. This unique melt indexer can carry out a single weight test according to ISO 1133 and ASTM D1238, procedures B, as well as ISO 1133 and ASTM D1238 Procedure C for the "Half Height / Half Diameter" standard.
The Melt Indexer Model MI-4. This unique melt indexer with automatic weight selection can carry out a single weight test according to ISO 1133 and ASTM D1238, procedures B, as well as ISO 1133 and ASTM D1238 Procedure C for the "Half Height / Half Diameter" standard. Tests can be made either with one test load (single load mode) or with several test loads per barrel filling (multiple test load mode).
New generation featuring highest accuracy
A new generation of the fully automated melt indexer. Pellets, powders and similar shaped materials can now be run and cleaned with one device.

Capillary Rheometers

The new base scaled model, extendable by approved options The smallest one from the RHEOGRAPH family, our RHEOGRAPH 20, controlled with CANBus technology, was not only developed on modern 3D-construction workstations but of course also with the experience and potential from more than 30 years of the numerous generations before.
Unparalleled speed range of 0.00004 - 40 mm/sec (= 1:1.000.000) is now available in single or multi barrel system configurations, opening up new possibilities in testing.
PVT Measurement isothermal/isobaric Air-cooled up to 500°
RHEOGRAPH with included Mini-Extruder!
A small extruder feeds the test barrel directly with hot melt, respectively with testable elastomer.
