Equivalency Chart

The below chart has been developed as a helpful guide to compare PVC resins produced in the U.S.A. It has been developed over the years to suit our needs in deciding where we are able to fit resins into our own production. Each resin and resin manufacturer produces a little differently and to different specifications. This chart is meant to be a guide,and helpful tool for our customers.
