Laboratory Description

The Thermal Analyses Laboratory of the Materials Engineering Section at IME has the mission of performing materials characterization, through thermal analysis techniques, to obtain viscoelastic parameters, transition temperatures, reaction kinetics, loss and storage moduli, among other thermal parameters. The current infrastructure includes a Differential Scanning Calorimeter (DSC) and a Dynamic Mechanical Analyzer (DMA), as well as benches for sample preparation.

Laboratory Infrastructure

• • Dynamic Mechanical Analyzer, model DMA 850, TA Instruments;

  • Differential Scanning Calorimeter, model DSC 404 F1 Pegasus, Netzsch;

  • Benches for sample preparation;

Competencies

• • Identification of mass changes due to interaction with the atmosphere, vaporization, and decomposition;

  • Analysis of physical and chemical processes involving energy variation;

  • Identification of enthalpy variation in polymer samples due to changes in their physical and chemical properties as a function of temperature or time;

  • Determination of viscoelastic properties and transitions;

  • Determination of shear modulus, loss modulus, and damping factor of polymer materials from the application of an oscillatory stress or strain;

  • Analysis and determination of glass transition temperature, melting temperature, crystallization temperature, heat of fusion and reaction, heat capacity, among other properties.
