Transition Temperature by DMA
Test ID
R-026
Description
A dynamic mechanical analyzer is used. A test specimen in the form of a circular disk or pellets is sandwiched between parallel plates, at temperature. The top plate is oscillated at 100 rad/s while the sample is cooled. The cross-over temperature of the G’ and G” curves is determined.
Options
Standards
- ASTM D4440
Data
Complex Viscosity v. Temperature, Shear Modulus v. Temperature, Strain Sweep, Tan Delta v. Temperature. This data appears in Matereality as Melt Rheology by DMA.
Replicates
Number of times this test is repeated: 1
Samples
2 plate rheology discs [details]
Application
This is a precise measure of the temperature where the material begins to solidify. It may be used to characterize the no-flow temperature of a material.
