# Polymer rheology analysis laboratory

## You want to carry out rheological analyses of polymers

### What is rheological analysis of polymers?

Rheological analyses of[polymers](https://filab.fr/en/our-services/our-analysis-services/polymer-materials-analysis-laboratory.md) are used to study the mechanical properties and behaviour of polymers under the effect of stress or deformation. They measure the way in which materials flow and deform in response to an external force, which is essential for understanding their behaviour as a function of temperature, pressure or time.

### Rheology and flow velocity of polymers

Polymer deformation and flow are issues related to the [characterisation of materials](https://filab.fr/en/our-services/our-analysis-services/polymer-materials-analysis-laboratory/laboratory-material-testing/) under stress.

- **The**[**deformation**](https://filab.fr/en/our-services/our-expertise-services/laboratory-analysis-failures/analysis-of-a-deformation-of-materials-in-laboratory.md)**of a polymer**refers to the change in shape or volume of a material in response to a force. There are two main types of deformation: elastic and plastic. Elastic deformation is temporary, meaning that the material returns to its original shape once the force has been removed. Plastic deformation, on the other hand, is permanent, meaning that the material does not return to its original shape once the force has been removed.

- **Polymer flow** refers to the continuous movement of a material under the effect of an applied force. It is a characteristic mainly associated with fluids, although some solids can also flow under certain conditions, particularly thermal conditions. Flow is influenced by the [viscosity of the material](https://filab.fr/en/our-services/our-analysis-services/chemical-analysis-laboratory/determination-of-the-viscosity-index-in-the-laboratory.md).

Knowing how a polymer deforms and flows can help predict its behaviour in structures under load, in product formulation and in the design of industrial processes.

### The main properties measured during rheological analyses of polymers

The main characteristics studied during rheological analyses of polymers are as follows:

- **[Viscosity](https://filab.fr/en/our-services/our-analysis-services/polymer-materials-analysis-laboratory/viscosity-index-measurement-on-polymer.md)**: the material’s resistance to flow.
- **Elastic modulus**: the ability of a material to return to its initial shape after deformation.
- **Viscous modulus**: the tendency of a material to flow irreversibly when a stress is applied to it.
- **[Viscoelastic](https://filab.fr/en/our-services/our-expertise-services/rheological-analysis-laboratory-polymer-rheology/laboratory-measurement-of-viscoelasticity.md) behaviour**: the combination of elastic (reversible) and viscous (irreversible) responses of the polymer.

### Why carry out rheological analyses of polymers in the laboratory?

Performing **[rheological analysis](https://filab.fr/en/our-services/our-expertise-services/rheological-analysis-laboratory-polymer-rheology.md)**of polymers in the laboratory enables the**viscoelastic, viscous and elastic properties**of materials to**be identified and quantified**, providing information for many industrial and research applications.

Understanding the rheology of polymers is important for the development and manufacture of many products, such as plastics, rubbers, adhesives, coatings and composite materials.
