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
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
