AbolishedDetermination of the viscosity of Poly(vinyl chloride) resins in dilute solution using capillary viscometers
用毛细管黏度计测定聚氯乙烯树脂稀溶液的黏度
Application Summary AI generated
This standard specifies a method for measuring the dilute solution viscosity of poly(vinyl chloride) (PVC) resins using a capillary viscometer. It is applied in the plastics industry for quality control and characterization of PVC resin grades, particularly to determine the K-value or intrinsic viscosity, which correlates with molecular weight and processing behavior. The method is used by resin manufacturers and testing laboratories to ensure consistency in PVC production and to predict material performance in applications like pipes, profiles, and films.
