Rotational Rheology Testing Service
Rotational rheometry stands as a sophisticated analytical method essential for delving into the intricate properties of materials, especially those exhibiting complex fluid characteristics. This technique is instrumental in unraveling the flow, deformation, and structural responses of various substances, spanning from fluids to semi-solids and solids. Through the application of controlled stress or strain and the measurement of resulting strain/rotation or stress/torque, rotational rheometry offers valuable revelations on material viscosity, viscoelastic attributes, and crosslinking mechanisms.
Rotational rheometry operates on the principles of rheology, which is the study of deformation and flow of materials. During analysis, samples are placed within a controlled geometry, such as a cone-and-plate or plate-and-plate setup, and subjected to a controlled stress or strain. The resulting strain/rotation or stress/torque is measured, allowing for the calculation of material properties like viscosity and viscoelastic moduli (G' and G").
The technique is based on the application of shear stress, which is the force applied parallel to the surface of the sample, causing deformation by shear or sliding. The response of the material to this stress, in terms of strain, provides valuable data on its rheological characteristics. This includes the material's resistance to flow, known as viscosity, and its energy loss during flow, quantified by the loss modulus (G").
At CD BioSciences, we pride ourselves on providing state-of-the-art rotational rheology testing services tailored to the needs of the environment-friendly materials industry. Our services are designed to support the development and analysis of sustainable materials, ensuring their performance and safety in various applications.
We employ a variety of rotational rheometry methods to cater to different material types and testing requirements. These include:
Shear Rheometry
This involves applying shear stress to the sample and measuring the resulting shear strain, providing data on viscosity and viscoelastic moduli.
Oscillatory Rheometry
By subjecting the sample to oscillatory stress, we can determine the material's viscoelastic properties, including the storage modulus (G') and loss modulus (G").
Creep and Recovery Tests
These tests assess a material's tendency to deform permanently under stress and its ability to recover after the stress is removed.
For accurate rotational rheology testing, we require samples that are representative of the material in question. The sample must be prepared and presented in a manner consistent with the testing method. We handle a variety of sample types, including:
Polymers
Both synthetic and natural polymers used in the production of eco-friendly packaging and other materials.
Biomaterials
Materials derived from renewable resources, such as bioplastics and biodegradable composites.
Suspensions and Emulsions
Common in the formulation of environment-friendly paints, coatings, and personal care products.
