Thermal Stability by Cone and Plate DMA
Test ID
R-025
Description
A dynamic mechanical analyzer is used. Material is placed between the cone and plate and heated to desired temperature. A time scan is performed at a constant frequency for a set period of time. The test is carried out in an inert nitrogen gas environment.
Options
This test can be performed in an air environment.
Standards
- ASTM D4440
Data
Complex Viscosity v. Time. This data appears in Matereality as Melt Rheology by DMA.
Replicates
Number of times this test is repeated: 1
Samples
0.5 kg of pellets [details]
Application
This test yields important information about the thermal stability of plastics. It provides an outer limit on barrel residence times in extrusion and molding applications.
