Impact Laboratories are capable of assessing the rheology of polymer melts.  The rheology of a polymer melt can give information on the molecular or polymer structure as it is the study of the flow and deformation of polymer melts.

Polymer processing behaviour is heavily affected by the rheology of the polymer melt.  Polymer processing exploits the deformation and flow of a melt to create products and rheology can give valuable information on how polymers will process.  Rheology is concerned with the relationship between stress, strain (change of shape) and time.
