Pvc K Value Chart

It has been developed over the years to suit our needs in deciding where we are able to fit resins into our own production.

Pvc k value chart. Commercially low molecular weights are available with k values in the range of 45 50 and extra high molecular weights have k values in the range of 80 104. Formosa s formolon suspension pvc resins are designed for today s applications and we actively work with customers to develop resins for tomorrow s applications. Low k values imply low molecular weight which is easy to process but has inferior properties and high k values imply high molecular weight which is difficult to process but has outstanding properties. 40 d feet f pipe size inches sch.

K value is an indicator of molecular weight. A measure of the molecular weight of pvc based on measurements of viscosity of a pvc solution. Select the appropriate k value for such and select d and f for schedule 40 pipe from the table below where k is the pipe diameter in feet. We also offer an extensive selection of dry blend compounds in diverse colors.

Our resins are available in many grades with inherent viscosities ranging from 0 66 to 1 1 and k values ranging from 56 to 73.
