Thermal Analysis

Thermal Analysis

Since materials and their products are used in a certain temperature environment, they will reflect different temperatures during use and show different thermophysical properties as they are heated, cooled or held at constant temperature. Theoretically, thermal analysis is suitable for almost any substance whether solid, liquid or a mixture of solid, involving a range of techniques used to determine the physical or chemical properties of the substance. Thermal performance is one of the basic properties of materials, and thermal analysis is important to a wide variety of industries, including polymers, composites, petroleum, inorganic and organic chemicals, and many others. It is an excellent technical tool for researchers and developers to identify the type of materials, improve the quality of materials and optimize the production process of products. At Alfa Chemistry, the specialists are experts in using comprehensive thermal analysis techniques for materials characterization, failure analysis and de-formulation investigations.

Thermal Analysis

Our Thermal Analysis Capabilities

Thermal analysis methods measure physical, mechanical, chemical, and thermodynamic changes taking place under differing temperatures and loads, and can pinpoint when and at what temperature significant changes occur. Alfa Chemistry offers highly reliable thermal analysis services, including thermogravimetric analysis (TGA), differential Thermal Analysis (DTA), differential scanning calorimetry (DSC), dynamic mechanical analysis (DMA), thermomechanical analysis (TMA) and etc.

Thermogravimetric Analysis (TGA)

TGA measures changes in mass or weight as a function of temperature or time. It used to evaluate thermal stability, calculate content of materials, find phase transitions, analyze degradation reactions, and study decomposition kinetics.

Differential Thermal Analysis (DTA)

DTA is an analytical technique to quantitatively identify and analyze the chemical compositions of a sample by heating the sample and recording the behavior of the sample, which includes the temperature and heat flow between phase transition (i.e., melting point, crystallization, etc.).

Differential Scanning Calorimetry (DSC)

DSC is a thermo-analytical technique for polymeric and non-metallic materials. It can be used to reveal phase transitions and reactions, measure the heat capacity of pure compounds, identify unknown materials, study crystallization kinetics, evaluate crystallinity and determine phase separation, etc.

Dynamic Mechanical Analysis (DMA)

Using deformation as the main variable for evaluation, DMA measures the modulus (stiffness) and damping (energy dissipation) of materials, particularly to study the viscoelastic behavior of polymers, determine the glass transition temperature, study changes in elastic modulus and determine effects of physical aging. Furthermore, DMA can used for advanced applications like stress-relaxation behavior and creep testing.

Thermomechanical Analysis (TMA)

TMA is used to study physical properties of viscoelastic materials under mechanical loading as a function of temperature and time. It determines the softening point of polymers, measures the thermal expansion, the thermal shrinkage, the glass transition, and the curing reaction.

Laser Flash Analysis (LFA)

LFA can be applied to a wide range of materials, including graphite, metals, ceramics, polymers, composite materials, etc. This technique is a non-contact and non-destructive measurement, not only can directly measure the thermal diffusivity, but also can calculate the thermal conductivity.
