Instrument Capabilities

Differential Scanning Calorimetry (DSC)


Differential Scanning Calorimeters (DSC) measure temperatures and heat flows associated with thermal transitions in a material. Common usage includes investigation, selection, comparison and end-use performance evaluation of materials in research, quality control and production applications. Properties measured by TA Instruments’ DSC techniques include glass transitions, “cold” crystallization, phase changes, melting, crystallization, product stability, cure / cure kinetics, and oxidative stability.

Temperature Range: -180°C to 550°C 

Detectable Information: Glass transitions, melting, crystallization, phase changes, heat capacity, cure kinetics, oxidative induction time

Thermogravimetric Analysis (TGA)

Thermogravimetric Analyzers measures temperatures and weight changes associated transitions in a material. Common usage includes decomposition, volatilization, residue, material composition analysis, decomposition kinetics, thermal and oxidative stabilities.

Temperature Range: 30°C to 1200°C

Detectable Information: weight change temperature, weight change amount, decomposition kinetics, residue.


Simultaneous DSC-TGA

Simultaneous DSC/TGA measures temperatures and heat flows and weight changes associated transitions in a material. Common usage includes investigation, selection, comparison, and end-use performance evaluation of materials in research, quality control and production applications. Properties measured include phase transitions, melting, crystallization, decomposition, volatilization, residue, decomposition kinetics, thermal and oxidative stability.

Temperature Range:30°C to 1500°C

Detectable Information: Phase transitions, melting, crystallization, heat capacity, decomposition temperature, decomposition kinetics


Thermomechanical Analysis (TMA)

Thermomechanical Analyzers (TMA) measure changes in the dimensions of a sample as a function of time, temperature, and force in a controlled atmosphere.

Properties measured by TMA include the material’s coefficient of linear thermal expansion (CTE), shrinkage, softening, and glass transition temperatures. Modulated TMA (MTMA) can be used for deconvolution of the Total dimension change signal into Reversing and Non-Reversing dimension change signals for separating expansion from contraction, shrinkage, and stress relaxation.

Temperature Range:-150°C to 1000°C 

Detectable Information: Coefficient of Thermal Expansion (CTE), sample expansion and contraction, softening points, glass transition temperatures, and delamination.

Dynamic Mechanical Analysis measures the mechanical properties of materials as a function of time, temperature, and frequency. In addition to basic material properties, DMA also quantifies finished part characteristics, reflecting the important contribution that processing has on end-use performance. DMA is commonly used to measure glass transition temperatures and secondary transitions, orientation caused by processing, cold crystallization and effect of crystallinity on mechanical properties, cure optimization, filler effects in composites, and much more. DMA provides an accurate measure of material strength (modulus) but also other important mechanical properties such as damping, creep, and stress relaxation.

Temperature Range: -150°C to 600°C 

Detectable Information: Glass transition temperature (Tg), secondary transitions, modulus, viscoelasticity (storage modulus, loss modulus, tan delta), creep and creep compliance, stress relaxation, shrinkage and shrinkage forces

A rotational rheometer is used to measure viscosity (eta) and viscoelasticity (G’, G” and Tan delta) properties of a material.  Rheometers can handle all kinds of samples from low viscosity liquids (e.g. water or solvents), semi-solid or soft gels, to high stiffness and high modulus solids.

A rotational rheometer can perform flow measurements to test the viscosity of a liquid as a function of time, temperature shear rate or shear stress. Flow tests can also be used to measure the yield stress and thixotropic properties of a structured fluids.  The rheometer can also perform dynamic oscillatory measurements to measure the viscoelastic properties of a semi-solid or solid sample.  Typical oscillation tests are used to verify the linear viscoelastic region; monitor thermoset curing or sample stability; quantify differences in different formulations; measure polymer melts to compare differences in their molecular weight and molecular weight distribution; measure sample modulus and elasticity change as a function of time and temperature; measure glass transition (Tg) and sub-ambient transitions of polymers or polymer blends. In addition, a rotational rheometer can also perform transient type of measurements to study creep-recovery and stress relaxation.

Temperature Range: -150°C to 600°C

Detectable Information: viscosity, yield stress, thixotropy, curing, modulus (G’, G” G*), damping factor (tan delta), glass transitions, sub-ambient transitions, stress relaxation, creep-recovery

Horizontal & Vertical Dilatometry

Horizontal & Vertical Dilatometers use a pushrod technique to measure change in length, the coefficient of thermal expansion (CTE), softening points, and determine phase and glass transitions. Both the horizontal and vertical orientations allow for forces to be applied over the measurement range, aiding in the detection of length changes over temperature profiles.

Temperature Range: -160°C to 1700°C

Detectable Information: CTE, softening points, phase, and glass transitions

Optical Dilatometry

Optical Dilatometers can be used for testing materials that would be deformed by pushrod pressure(s). High performance light beams are shined onto samples, and their resulting shadow allows for the determination of material changes in shape and dimensions as a function of the temperature without physical contact with the specimen. The measurement method is entirely independent of any possible expansion or contraction of the instrument. It is the ideal instrument for studying incoherent materials, plastic or viscous materials, sintering kinetics, and thin samples.

Temperature Range: 30°C to 1650°C

Detectable Information: CTE, softening points, phase, and glass transitions

Laser & Xenon Flash instruments measure the speed with which materials transport heat. Metals, steel, aluminum, glass, ceramics, carbons, and polymers can be tested to determine thermal diffusivity, as well as specific heat and thermal conductivity.
