Hitachi TMA 7000 series Thermomechanical Analyzer


The Hitachi TMA7000 Series Thermomechanical Analyzer has doubled its sensitivity compared with our conventional model. It measures a wide range of samples, including thin film and small samples, as it uses the total expansion method and does not limit sample shapes. Changing the modes between push, penetration, and tension is done by simply replacing the probe. A wide range of options, such as an automatic cooling unit, ensures the ease of use and highly accurate measurement.

High Sensitivity



TMA7000 is equipped with newly developed "Z-stabilizer" signal optimization technology, which cuts noise levels to achieve highly sensitive measurements.

High-Temperature High-Humidity Measurements

Additional options allow measurement under high temperature and high humidity conditions. Furthermore, it is extensible to swelling and vacuum measurements.

The Eco-Friendly Cooling Unit



The eco-friendly cooling unit cuts liquefied nitrogen consumption by approximately 40% (compared to previous models). Electrical cooling units that do not use liquefied nitrogen can also be connected.

Effective Atmosphere Control

A mass flow meter can be incorporated into the gas control so the atmosphere can be efficiently controlled by not only the purge gas ON/OFF switch but also programmed flow rate control.

Improved Temperature Control Function

The new built-in temperature control function is designed to reduce the gap between the program temperature and the measurement sample temperature and improve temperature compliance.

Application:

Thermal Expansion of Polyvinyl chloride (PVC)

CTE (coefficient of thermal expansion) changes at the glass transition temperature. CTE after Tg is approximately 4 times larger.

Penetration on Polymer film


Comparison of softening temperatures between different polymer films, Polyethylene, Polypropylene and Nylon evaluated by penetration measurement.

Anisotropy of Polyethylene (PE) film

In above measurements of PE film, tension force is applied in machine direction (MD) and the transverse direction (TD).

Stress-Strain characteristic of Polyethylene (PE) film


The measurements are carried out on PE film with strain control mode at different temperature.

Stress-Strain Capabilities

The TMA 7000 series has stress strain measurement and analysis capability. Stress-Strain characteristic, Creep/Recovery, Stress Relaxation can be measured, and furthermore, applying sinusoidal force to samples the dynamic viscoelastic behavior can be characterized.
