Polymer Characterization
 High
Resolution Thermogravometric Analyzer (TGA):
Measures weight loss/gain as a function of temperature; Looks for
volatiles; -60° to 600°C
Modulated
Differential Scanning Calorimeters (DSC):
Measures heat flow and characterizes material transitions; Cures
reactions of various thermosetting materials; -60° to 400°
C; System uses an intercooler to reach lower temperatures
Standard
Differential Scanning Calorimeters (DSC):
Measures heat flow and characterizes material transitions; Cures
reactions of various thermosetting materials; -150° to 400°
C; System uses liquid nitrogen to reach lower temperatures
Dielectric
Analyzer (DEA):
Measures dielectric response and is used to characterize material
transitionsand monitor cure behavior; 20° to 400° C
Rheometrics
ARES System (DMA):
Used for characterizing viscoelastic solids and liquids. Performs
torsion tests under dynamic, static, or steady state modes. Used
to characterize shear viscosity and shear modulus as a function
of temperature, frequency or strain rate; -150° to 400°
C
Dynamic
Mechanical Analyzer (DMA):
Same as ARES but for viscoelastic solids only and operates in bending;
25° to 400° C
Thermo-mechanical
Analyzer (TMA):
Used to measure thermal expansion and contraction; -150° to
400° C
Rheovibron:
DDV II (also a DMA):
Displacement of 20 m; Tension testing on thin films at very low
stress; Measures modulus as a function of frequency or temperature;
used for cure stress measurements
Rheovibron:
DDV III (also a DMA):
Displacement of 2mm; Can do same mechanical testing as an INSTRON,
but at a smaller level
 fatigue:
adhesion tests
tensile:
3.0 bend fixture
K1C: fracture
toughness measurements
HS1000
HiSpeed Scanning Acoustic Microscope:
Pulse-echo and thru-transmission scans; used to detect interfacial
debonding
Flow
Microcalorimeter (FMC):
Measures heat and solution concentration; used to determine the
heat of adsorption of molecules onto surfaces
FTIR
Spectrometer:
Measures transmittance as a function of infrared wavelength; used
to identify unknown materials; study cure reactions
