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.

What does PVC stand for in PVC pipe?
Polyvinyl chloride PVC = polyvinyl chloride, a synthetic resin preparedd by the polymerization of vinyl chloride
What is formula to calculate k value of PVC resin?
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 are PVC pipes?
PVC or polyvinylchloride. IN other words ~ plastic pipe. k
How do you find the radius of a PVC elbow?
just buy a PVC with a 90 degree already on it, then hook up a straight hose!
