Rheology and Polymer Processing

Overview

The final product properties of any polymeric material are highly influenced by the way it is processed in a typically melt-processing operation such as in a screw extruder or in an injection molding machine. The polymer melt processing operation is in-turn highly influenced by the melt rheological properties of the polymers that affect both the processing operation (inside the extruder, etc.) and outside. While shear viscosity is important for determining the power requirements of the processing equipments, the melt extensional properties like extensional strain hardening (typically present in long-chain branched polymers) is essential in processing operations that involve free-surface flows that involve stretching operations along streamlines (film casting, film blowing, fiber spinning, thermoforming, blow molding, etc.). CSIR-NCL has expertise in both polymer processing and rheology.
