Two equal-size pieces of the same material are sheared between a fixed and moving plate for the measurement of shear modulus, G. This mode is ideal for soft materials such as gels, pressure sensitive adhesives, and high viscosity resins. You can count on the DMA 3200 for the precision measurements of force, displacement and temperature required for DMA results as well as the mechanical robustness and durability required for many-million cycle fatigue tests. The bottom figure shows strain sweeps on two cylindrical rubber samples, tested using compression clamps, at a temperature of 30C and frequency of 10 Hz. The same clamp is used for single Download and the self-extracting file to install your latest NanoSeries Software. In addition, your input regarding our software products is important to us. High Resolution OpticalDisplacement Sensor. Axial DMA tests on thin films requires maintaining the axial force above the oscillation force to hold the sample in tension throughout the test. Prediction of impact resistance, testing of creep or cold flow, cure behavior. Whether you are gaining insight for research and development or for quality control purposes, TA believes you should be confident in your measurements. Expandable with software options that extend the power of WinTest for specific applications, including a DLL interface to communicate with user-written software such as LabView or MATLAB. April 27, 2023 - TA Instruments Products. The data reveal a semi-crystalline structure with two amorphous relaxations and the DHRs force-tracking capabilities in such tests. DMA experimental methods include temperature ramps, temperature sweeps, strain sweeps, and frequency sweeps. This test demonstrates how the DMA 3200 can be used for a high cycle test, leveraging its high acceleration and durability attributes. Differential Scanning Calorimeters (DSC) Thermogravimetric Analyzers (TGA) . Description Features Applications Axial Bending, Tension and Compression With its unique Force Rebalance Transducer (FRT), the ARES-G2 rheometer is the only rotational rheometer capable of performing linear Dynamic Mechanical Analysis (DMA) on solids in bending, tension and compression. Supported Operating Systems: 64-bit version of Windows 7, 8, & 10 Ultimate, Windows 11, Enterprise & Professional. Building on superior technologies of the world's best-selling DMA, improvements in every aspect of DMA performance deliver the most accurate and reproducible measurement of mechanical properties over a wide temperature range. endobj TA Instruments. <> Typical training time: 2 Hours. The sensor is placed close to the sample and loading axis to further minimize errors in compliance or thermal expansion. All rights reserved. Parallel plate compression measurements are most suitable for low to moderate modulus materials such as foams and elastomers. Axial sample deformation is applied by driving the high sensitivity FRT in controlled strain sinusoidal oscillation, unlocking all new capabilities for solids testing. In addition, the frictionless, moving-magnet design eliminates failure points that exist in other motor designs, such as moving wires and bearing degradation. The ACS-2 and ACS-3 models permit operation of the DMA 850 withStandard Furnace at temperatures as low as -50 C and -100 C respectively *. Rubber Testing. dennis.ndaya@uconn.edu This efficient, quiet, and lubrication-free motor technology allows the DMA 3200 to be used virtually anywhere; from lab to production floor, or from the cleanroom to office space. View DMA BrochureDMA AccessoriesRequest a Quote. The Scarabaeus Software for instrument control and data analysis is a powerful and versatile system for programming experiments, providing quick feedback of results, and managing data from all rubber testing instruments. The DMA 3200 features a variety of sample clamping systems that provide multiple modes of deformation to accommodate awide range of sample stiffness. Dynamic Mechanical Analysis (DMA) | Institute of Materials Science as composites, ceramics, glassy and semi-crystallinepolymers, and metals. Superior temperature stability is achieved through the use of twin element resistive gun heaters, which provide counter-rotating air flow into a uniquely shaped oven chamber which optimizes gas mixingfor uniformity and stability over the temperature range of -150C to 600C*. Note: This software supports TAM Air instruments. <> In mechanical testing, an instrument design with highly stiff components, such as the frame, connecting components and sample clamps, are criticalfor measurement accuracy. A rotational rheometer is used to measure viscosity (eta) and viscoelasticity (G, G and Tan delta) properties of a material. WinTest software is supported by a full range of services including onsite training, free online training sessions, and customer service that is only a phone call away. Backed by over four decades of TA Instruments expertise in rotational rheology and linear DMA measurements, the Discovery Hybrid Rheometers DMA Mode adds a new dimension for testing solid and soft-solid materials. The sample dimensions were a diameter of 10 mm and thickness of 20 mm. endobj The FCO is the premier temperature device for materials testing and is designed to optimize temperature response time, uniformityand stability. The flat baseline of the DSC 250 and rugged DMA 850 frame deliver clear and accurate measurements allowing you to quantify formulation impacts on the cured composites cure strength, flexibility, adequate end use temperature ranges, and more. Powered by the FRT technology, the DMA mode does not require the installation of external components, so it is always quick and easy to get great data! A 2.5 L liquid-nitrogen filled dewar with heat exchanger cools nitrogengas (2 bar to 8 bar, 30 L/min) before being fed to the DMA 850 Standard Furnace. Copyright 2023. The DMA 3200 motor delivers a force output of up to 500 N and controlled displacements ranging from 1 micron to 13 mm. Monitor test progress with up to 4 configurable real-time data, high-speed scopes. <> Copyright 2023. Properties measured by TA Instruments DSC techniques include glass transitions, cold crystallization, phase changes, melting, crystallization, product stability, cure / cure kinetics, and oxidative stability.
