DMA

Dynamic Mechanical Analysis (DMA)

 

TGA TMA Thermal Conductivity
DMA DSC

 

It is to make the sample under the temperature controlled by the program, adding single frequency or multiple frequency oscillating force, to study the mechanical behavior of the sample, measure the function relationship in storage modulus, loss modulus and loss factor with the change of temperature, time and the frequency of the force. It is widely applied to the industries of thermoplastic and thermosetting plastic, rubber, coating, metal and alloy, inorganic material, composite, etc.

 

DMA Typical Application

1.rigidity(E’)

2.damping force characteristic (E”, tgδ)

3.creep and stress relaxation

4.hysteresis and internal friction

5.glass transition

6.phase transition

7.Softening temperature

8.secondary relaxation

9.solidification process
