The K value of PVC resin is calculated using the Fikentscher K value equation, which is K = (135.5 - 0.31 * log(viscosity)) * (1 - 0.008 * (log(viscosity) - 1)), where viscosity is the intrinsic viscosity of the PVC resin solution. In practice, the viscosity is typically measured using an Ubbelohde viscometer or an Ostwald viscometer. The K value is an important parameter that indicates the average molecular weight of the PVC resin and is used to classify different grades of PVC based on their properties and applications.

What is K-value in PVC resin?
K Value is an indicator of molecular weight : K-57 is medium for injection molding,K-67 is medium-high for rigid extrusion, K-70 is higher for plasticized extrusion or calendering. K value relates to other ASTM indicators of molecular weight like Intrinsic Viscosity or Inherent Viscosity.
