ADVANCED Rheology Solutions SUPPORTED by NETZSCH

Unlock Deeper Insights From Your Rheology Data

Seamlessly connect your test data from any Kinexus or Rosand rheometer with advanced analysis and predictions using the IRIS (Interactive Rheology Information System) interactive software.

About IRIS

IRIS (the Interactive Rheology Information System) is a collection of key rheology modeling tools for easily analyzing rheological data. Over 25 years ago, Bingham Medalist and Rheologica Acta Editor Professor Henning Winter and his collaborators pioneered the concept of interactive rheology analysis.

This groundbreaking tool stands alone in its ability to provide a more in-depth understanding of experimental rheology data. IRIS's user-friendly graphical interface with customizable graphs can enhance productivity by providing faster insight into trends and correlations in your data. The ability to overlay experimental data and model predictions provides a broader perspective on material behavior and mechanisms. The guided, stepwise analysis allows for a range of complexities, from basic curve fitting to advanced constitutive modeling, including non-linear viscoelasticity.

Whether you are analyzing polymers, adhesives, pharmaceuticals, foods, or cosmetics, IRIS has a tailored solution for you!

“I’m excited to share that NETZSCH has released a software update enabling seamless data export directly into IRIS Rheo-Hub. This creates a fast, integrated path from measurement to insight, bringing IRIS’s advanced analytics directly to NETZSCH rheometer platforms.”

Elevating Rheology Capabilities

IRIS Rheology advances material discovery and design by integrating rheological experiments with data-driven analysis, machine learning, modeling, and high-quality visualization to turn complex data into clear insight.

Key advantages or IRIS Rheology are:

Advanced rheology modeling
Analyze linear and non-linear viscoelastic behavior using RelaxationWhen a constant strain is applied to a rubber compound, the force necessary to maintain that strain is not constant but decreases with time; this behavior is known as stress relaxation. The process responsible for stress relaxation can be physical or chemical, and under normal conditions, both will occur at the same time. relaxation spectra, constitutive models, CreepCreep describes a time and temperature dependent plastic deformation under a constant force. When a constant force is applied to a rubber compound, the initial deformation obtained due to the application of the force is not fixed. The deformation will increase with time.creep compliance, and material functions.
Fast master curve generation
Perform time–temperature, time–pressure, concentration, Curing (Crosslinking Reactions)Literally translated, the term “crosslinking“ means “cross networking”. In the chemical context, it is used for reactions in which molecules are linked together by introducing covalent bonds and forming three-dimensional networks.curing-state, and Kaelble shifting for reliable master curve construction.
Time-resolved rheology analysis
Study gelation, Curing (Crosslinking Reactions)Literally translated, the term “crosslinking“ means “cross networking”. In the chemical context, it is used for reactions in which molecules are linked together by introducing covalent bonds and forming three-dimensional networks.curing, drying, stability, and structural evolution under realistic processing conditions.
