Thermal analysis rheology

Thermal Analysis & Rheology

  • A complementary set of analytical techniques

  • Instruments and software for characterizing a wide range of materials

  • Measures changes in the Physical, and Chemical properties of materials as a function of time, temperature and other specific variables.

What is Rheology ?Rheology is the science of flow and deformation of matter.The relationship between stress and deformation is a property of the material. We can therefore define Rheology as the study of stress-deformation relationships.

What is a Rheometer?

An instrument that measures both viscosity and viscoelasticity of fluids, semi-solids and solids

It provides following information about the material’s:

Viscosity (which is the function of shear rate or stress, time & temperature dependence)

Viscoelastic properties (G’, G”, tan d) with respect to time, temperature, frequency & stress/strain

Transient response (relaxation modulus, creep compliance, creep recovery)

Thermal analysis of materials

Thermal Analysis of Materials

Thermal Analysis techniques are applicable to most material

classes. Some of the more common classes include :

  • Polymers (Thermoplastics, thermosets, Elastomers, Polymer blends, copolymers).

  • Foodstuffs and Pharmaceuticals

  • Inorganic (Minerals & Clays)

  • Ceramics, metals and Alloys.

  • Petroleum derived products (fuels, greases, Lubricating oils, Bitumens and tars).

  • Materials are investigated (Loaded) in the liquid or solid state.

  • Over a wide temperature range -180°C/1600°C (depending on the technique).
