Elongational flow refers to the stretching deformation of a polymer melt under extensional stresses, as encountered in film blowing, fibre spinning, foaming and advanced extrusion techniques. Unlike ...

Reactive extrusion is a versatile, continuous processing technique in which chemical reactions and polymer shaping occur simultaneously within an extruder. When applied to linear polyolefins such as ...

Rheology techniques comprise experimental methods used to characterize the flow and deformation behavior of materials under applied stresses or strains, typically by quantifying relationships between ...
