Dynamic Mechanical Analyzer (DMA)

General description:

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 the characteristics of finished parts to highlight the significant impact of processing on end-use performance.

Applications:

Measurement of glass transition temperature and secondary transitions, treatment-induced orientation, cold crystallization, curing optimization, the effects of fillers in composites, etc.

Characteristics :

• Temperature range: -160 °C to 600 °C. Down to -100 °C without liquid nitrogen.
• Frequency range: 0.001 to 200 Hz
• Strain resolution: 0.1 nm
• Maximum ramp rate of 20 °C/min for heating, 10 °C/min for cooling.
• Available grips: Single and double cantilever, three-point bending, film, sandwich shear
• The low-mass, contactless motor provides a continuous force range from 0.1 mN to 18 N, enabling measurement of all types of materials, from the softest to the stiffest
• The frictionless air-bearing design ensures both improved sensitivity and greater force accuracy
• Exclusive optical encoder technology provides 0.1 nm resolution over a continuous 25 mm travel range, offering unmatched versatility
• The new DirectStrain™ feature and automatic measurement range selection allow you to analyze a wide variety of samples in terms of stiffness and frequencies and obtain the best data in a single run, every time
• Special high-stiffness, low-mass fixtures are easy to use and ensure data repeatability
