WebIn his efforts, rheology is used as a tool to solve practical problems in polymer processing. In general, it is difficult to understand polymer and plastic processing without understanding their rheology. Therefore it is crucial to relate polymer rheology with molecular structure and processability. This is the main philosophy of Expert's research.

WebOct 21, 2024 · The molecular structure of a polymer melt determines which behavior is dominant (viscous or elastic). For example, too much elasticity can lead to flow anomalies and unwanted effects during many common processing steps. Rheology viscoelastic tests WebIf the polymer is a rigid and tough material then it has higher elasticity and therefore has high storage modulus and correspondingly lower loss modulus giving smaller height of Tanδ peak. For...
