Using several techniques, our scientists can tell you the degree of crosslinking in your:
Crosslinking influences mechanical properties, swelling behavior, and wear resistance in many materials.
Swell ratio testing is usually conducted on crosslinked materials. In this test, a sample is placed in a good solvent at a particular temperature, and the change in height of the sample is monitored as a function of time. The crosslink density and molecular weight between crosslinks can be calculated from the final swell ratio using details of thermodynamic interaction between the sample and the solvent.
The following tests will report swell ratio, crosslink density, and other parameters associated with crosslinking.
Density measurements are sometimes performed along with crosslinking measurements. Density is commonly performed by two techniques at Cambridge Polymer Group.
