ActivePlastics—Determination of the transient extensional viscosity of polymer melts
塑料 聚合物熔体瞬态拉伸黏度的测定
Application Summary AI generated
This standard specifies a test method for measuring the transient extensional viscosity of polymer melts, which is critical for understanding material behavior during stretching flows. It is applied in the plastics industry for quality control, process simulation, and material development, particularly in applications like film blowing, fiber spinning, and blow molding where extensional deformation dominates.
