Mooney Viscometer
ASTM D1646
Summary
The test methods in this standard measure Mooney Viscosity, the shearing torque resisting rotation of a cylindrical metal disk (or rotor) embedded in rubber within a cylindrical cavity.
Test Details
There are a few valuable takeaways that can be achieved through running ASTM D1646. Running a material at a few different test temperatures provides viscosity values. Coupled with the stress relaxation characteristics taken away from this test, the elastic and viscous response can be utilized to predict processing characteristics. Finally, the pre-vulcanization characteristics are measured to determine the scorch time associated with early stages of vulcanization.
