TA Instruments – Thermal Analysis – Dynamic Mechanical Analyzer
Dynamic Mechanical Analysis measures the mechanical properties of materials as a function of time, temperature, and frequency. In addition to quantifying viscoelastic properties of materials, DMA can also quantify finished component and product characteristics, reflecting the important contribution that processing has on end-use product performance. DMA is commonly used to measure glass transition temperatures (Tg) and secondary transitions, orientation caused by processing, cold crystallization, cure optimization, filler effects in composites, and much more. DMA provides an accurate measure of material modulus and product stiffness plus other important mechanical properties such as damping, creep, and stress relaxation.
Key Features
- Non-contact, low mass motor delivers continuous forces from 0.1 mN to 18 N to measure everything from soft to stiff materials
- Frictionless, low-compliance air bearing design ensures superior force sensitivity and accuracy
- Unique optical encoder technology provides 0.1 nm resolution over a 25 mm continuous range of travel for ultimate testing versatility
- New DirectStrain™ and Intelligent Autoranging controls allow you to measure the widest range of sample stiffness and frequencies for the best data, the first time, every time
