POLYMER MATERIAL TESTING FOR DYNAMIC VISCOELASTIC PROPERTIES
DMA or Dynamic Mechanical Analysis is a powerful analytical technique for investigating the temperature and frequency-dependent behavior of polymeric materials and components.
Polymers and Non-linear Materials:
The properties of polymers like plastics, rubbers, and typical composites, are time and frequency dependent. These properties are viscoelastic. Dynamic Mechanical Analysis or DMA is an effective method to characterize these materials or products with respect to time, temperature and frequency. The DMA technique measures the stiffness and energy disspation properties of these materials.
AdvanSES can provide the following types of dynamic test data to fully characterize viscoelastic materials and products manufactured using these materials;
Dynamic Material and Product Testing Services (DMA)
- Storage Modulus (E’, G’)
- Loss Modulus (E”, G”)
- Tan Delta
- E”, E’ and Tan delta with Frequency sweep
- E”, E’ and Tan delta with Temperature sweep
- Glass Transition and Softening Temperature
- Material Constants Testing for CAE
Polymer materials can be aged in suitable mediums like oils, air, water etc., as per their field service conditions and Dynamic Mechanical Analysis (DMA) can be carried out to study the material properties before and after aging.
