Because the glass transition is one of the major predictors of polymer behavior in amorphous and semi-crystalline polymers, thermal analysis is closely associated with polymers.

These include:

  • Thermoplastics – materials that can be reheated without changing

    • Glass transitions

    • Melting point

    • Crystallization behavior (controlled cooling, isothermal, on reheating)

    • Initial crystallinity by HyperDSC™

    • Overlapping transitions by MDSC™ or StepScan™

    • Heat capacity

    • Thermal Conductivity by MDSC™

    • Filler content

    • Composition (TGA and FTIR)

    • OIT

    • Modulus and damping

    • Stress, Strain and Frequency Effects

    • Time Temperature Superposition

    • CTE

  • Thermosets – materials that cure and change dramatically after heating

    • Most thermoplastic tests on cured forms

    • Degree of cure

    • Curing onset and energy

    • Relationship between degree of cure and properties

    • Viscosity profile of cure

    • Off-gassing and residual ash content

    • Residual cure

  • Rubbers and elastomers – materials with their glass transition below room temperature

    • Glass transition and other tests from above

    • Composition analysis in TGA

    • Oxidative Induction Time

    • Rheological properties from DMA
