The test is used to determine the K value of PVC in a diluted solution at a temperature of 25 °C. The K value provides information for characterising the polymerisation of VC polymers.
The complete laboratory set for the determination of the K-value includes a Ubbelohde viscometer with measuring stand, the viscosity tester with printer, the bath thermostat with flow cooler and various items of glassware. Up to 10 automatic measurements can be taken per test series. These can be accessed via the display of the measuring device. A measurement printer can then be used to print the results. To make the test even easier, we recommend a unit that prepares the samples automatically and an optional piece of software for evaluating and archiving your test results.

The analytical balance is required in every test laboratory. It is used to precisely determine important values such as MFR, carbon black content, K-value, degree of crosslinking, OIT, volatile components, water absorption and similar.
