Product category: Measuring and test equipment for rheological properties

ADDICHECK - Monitoring of formulation and viscosity with one

Quality control of formulation components and viscosity is essential in plastics polymerization and processing to avoid scrap material and extended costs. A compact test arrangement for the operation on the process extruder is not available in the plastics industry so far.
GÖTTFERT Werkstoff-Prüfmaschinen GmbH in cooperation with Inno-Spec GmbH and Kunststoffzentrum SKZ has developed a formulation sensor system AddiCheck. The sensor is used directly in an Online-Rheometer and therefore an operation at absolute stable process conditions is assured.

The system consists of a spectrometer and a solide optical reflexion probe applicable for use at 400°C and 500°C . Moreover the probe has also been enhanced for good self-cleaning function and can therefore operate continuously without any additional cleaning.

The first version of AddiCheck is focusing first for application with polyolefins and operates in wavelength range of 950- 1650 nm in the near-infrared (NIR) region. Extension capability to cope with technical plastics and larger ranges of wavelength is possible.

The AddiCheck system can be used for determination of individual formulation components with a high accuracy level and detection limit of up to 0,01%. This is particularly relevant for antioxidants and light stabilizers of typical quantity between 0,05 and 0,5 Gew.-%.

A new high quality level in online quality process control is achieved by integration of the AddiCheck system for simultaneous determination of rheological values and concentration content. Details on the AddiCheck formulation sensor are available at the GÖTTFERT booth H10 J55 at the K show 2016 in Düsseldorf.

CONTIFEED -

Our fully automated Melt Feeding Unit

The CONTIFEED offers new possibilities for determination of process-related rheological
test data. The system is combined of a capillary rheometer Rheograph 50 and a Mini-Extruder.
The Extruder feeds the test barrel of the Rheograph with melt, which ensures an air bubble free filling of the test barrel.
This continuous method of melt feeding contributes to a significant timesaving during the tests.
The reduced material residence time under influence of elevated temperatures is just one of the advantages due to shortened heating time by optimized and effective heating system.

As a result of this short heating time the CONTIFEED is specially suitable for elastomers and thermally less stable material.
By pre-plastification also powder materials, e.g. PVC dry blends can be measured.

Capillary Rheometer

The new high-pressure capillary rheometer series with an extensive range of options

The current Rheograph series is available in single or multi-channel design with a test load of up to 120 kN and a dynamic speed range of up to 40 mm / sec (2400 mm / min). The automatic pressure transducer recognition "Plug & Test" is certainly the right choice. The sensitivity of the pressure measurement was increased by 10 times compared to the previous model.

The new bus control electronics and a precision drive, were the focus of this new development. The convenient 5.7 "color touch screen, the script flow control for your own procedures or the preparation for options such as PVT, thermal conductivity or Shark-Skin determination are also only excerpts.

For the measurement sequence and the extended evaluation, multifunctional tools are delivered with the LabRheo operator software as well as WinRheo II (EXCEL®-based).

Database access from the external system and the csv export are easy to implement.

A remote maintenance software can be used for fast fault analysis or for training purposes.

Dynamic Online Rheometer - DOR

Breakthrough in dynamic online rheometry – The DOR !
For correlative determination of the structural properties of Polymers !

Dynamic tests are required for the determination of the structural properties of Polymers.
With previously used Online Capillary Rheometer just the determination of rheological properties in stationary mode was possible.

The DOR enables both, simultaneous determination of visco-elastic properties in dynamic mode, as well as the online measurement of viscosity and melt index in stationary mode.

Continuous determination of visco-elastic properties of polymer melts.

Online determination of module G’ and G’’ in frequency range from 0,1 Hz up to 25 Hz, depending on test material.

PVT -

PVT Measurement isothermal/isobaric air-cooled up to 500 °C
(ISO17744)

The new test device PVT is specifically designed for measurements of PVT isothermal and PVT isobaric.

With this device thermodynamic properties, the specific volume of the polymer as a function of temperature and pressure, can be determined.

These data are particularly important for the simulation of the injection moulding process. But

they also can be used to describe any process of shrinkage during cooling as for example in extrusion.

The measurement can be performed in two possibilities:

Isothermal – at constant temperature and changing pressure or

Isobaric – at constant pressure with different cooling rates.

The device is characterized by its compact test chamber and by its new optimized cooling system.

The cooling medium is air, therefore no cooling water connection is required.

As an option also the thermal conductivity of the material can be measured acc. ASTM D5930 / ISO 22007-1

SLR - Spin Line Rheometer

Extensional Rheometer for high Haul-off Speeds

Melt spinning is an important production process for chemical fibers made of synthetic or biologically based polymers.
The new Spin Line Rheometer introduced by GÖTTFERT is a measurement system to characterize the spinnability of polymers in lab scale. The system can be installed under an extruder or a capillary rheometer and is able to measure the strand force and therefore the extensional viscosity at spinning speeds of up to 7000 m/min.
The strand is guided around the diversion-wheel that is placed horizontally below the extruder die.
The wheel is installed on a highly sensitive force sensor with a resolution of 0,05mN that measures the draw-down force in the strand. The strand is accelerated by the take-off wheel installed on a high-speed electric motor. A strand guide makes multiple wrappings possible.
A Venturi-Die is used to separate the strand from the take-off wheel. Optionally an optical measurement system can be installed to measure the strand profile at various positions between the die and the diversion-wheel. A new, extended version of the Rheotens-Software is used to control the measurement system and to analyze the data.

The Software can be connected to higher-level bus systems. With an optional self running Online Sampler System for material feeding a non-stop operation is guaranteed.

Company details

The company GÖTTFERT-Werkstoff-Prüfmaschinen GmbH was founded in 1962 by
Prof. Dr. Otto Göttfert. In the second generation now his son Dr. Axel Göttfert took over the leadership as sole managing director.
As one of the leading companies in the field of rheology and material characterization, GÖTTFERT is the only
independent organization that specializes in this market niche, leading the market with the introduction of innovative products. Its instruments for thermoplastics, thermosets and
elastomers are used in laboratories and in production settings worldwide. The instruments are built in small production runs, modular in design and they can be made to fit almost
everyone`s need.

The high flexibility of technology in terms of rheology leads to a series of autarkic rheometer species that is reflecting GÖTTFERT`s production program, namely: Monitoring of polymer characteristics in the production process („Online Technology“, „AT-Line Technology”, „Filmanalysis”); or quality control in the application laboratory („Melt Index“) and rheological characterization of new materials („Capillary Rheometers“, „Elastomer Testing“), or in pilot plant application („Extrusion Equipment)
All GÖTTFERT`s systems fulfill highest possible demands of quality and innovation !

MADE BY GÖTTFERT – stands for taking responsibility. It also means that you cannot
