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
