Rheometer

Rheology (from the greek rhei = flow and logos = doctrine) deals with the deformation und flow characteristics of materials. Rheometer stands for measuring devices which are used to determine the deformation and flow behavior.
In the rubber industry the rheometer is applied for the determination of the flow characteristics of rubber compounds. During the vulcanization the viscosity of the compound rises heavily and reaches a maximum after the finishing of the vulcanization process. The rheometer measures the strength during the vulcanization which is needed for the deformation of the test specimen.
The change of the strength over the time is called the rheometer curve. These curves help to evaluate the quality of the rubber compound. They also help to adjust production parameters for the processing of compounds.
