What Does MWD Stand For?

MWD stands for Molecular Weight Distribution

Molecular Weight Distribution (MWD) refers to the range of molecular weights present in a polymer or other macromolecular substance. It is a critical parameter in characterizing materials, influencing their physical properties, processing behavior, and applications. MWD is typically represented by statistical measures such as number average molecular weight (Mn), weight average molecular weight (Mw), and polydispersity index (PDI), which provide insights into the uniformity or variability of the molecular weight of the sample. Understanding MWD is essential for tailoring material properties for specific industrial and scientific applications.
