I want to measure rheological properties – from fluids to soft condensed matter to solids
The measurement of rheological properties is applicable to all material types – from fluids to semi-solids and even solid systems such as polymers and composites. Understanding the rheological properties of materials can help to develop a better product – since these physical properties often link material formulation and processing stages with the ultimate end use and product performance in the hands of customers and consumers.
Rheology is defined as the flow of fluids and deformation of solids under applied stresses or strains. Rheometers are the instruments used to measure a material’s rheological properties. There are many types of rheometers that are available with the most versatile being controlled stress and/or strain rheometers and capillary rheometers.
Whether your objective is to measure fluid properties such as viscosity as a function of shear rate to determine non-Newtonian flow behavior, or whether you want to measure complex rheological properties such as viscoelasticity (G’, G”) as a function of frequency (time) or temperature, Malvern’s rheometers are in use around the world to help apply rheology solutions to a wide variety of industries.
I want to study the rheology of:
Rheology of suspensions, dispersions or emulsions The rheology of many fluid systems, and suspensions, colloidal dispersions, and emulsions is critical to product performance and process efficiency.
Rheology of semi-solid materials such as gels, pastes, creams and ointments The rheology of semi-solid materials is important in many industries including pharmaceutical, foods, cosmetics, and consumer products.
Rheology of polymer melts The rheology of polymers and plastics are critical for determining molecular architecture, processing behavior, and end product performance.
Rheology of asphalts The rheology of asphalt binders are key to understanding and predicting pavement performance over a wide range of climatic, environmental, traffic, and loading conditions.
