Evaluation of O-ring by low temperature TMA

TA-1024: Evaluation of O-ring by low temperature TMA


Fluoroelastomer O-rings are noted for their resistance to high temperature and to a wide variety of chemicals. In this application, we demonstrate the use of low temperature TMA with differential type compression loading attachment to evaluate the mechanical properties of an O-ring measured in the X and Y direction. Thermomechanical analysis (TMA) is a method in thermal analysis that determines the mechanical property of a material by evaluating the change in length as a function of temperature or time. A differential type compression loading method is especially effective for measuring small-sized sample with high accuracy.

TG-DTA is a hyphenated technology generally referred to as simultaneous thermal analysis (STA).



DSC is a thermal analysis technique that quantifies the amount of energy in a reaction.

DSC with industry-first self-diagnostic feature and industry's highest temperature range

Quantifies the energy changes in reactions such as melting, transition, crystallization and glass transition temperature.

DSC8271 is a high-temperature type DSC with a maximum temperature of 1,500°C.

TMA is the measurement of a change in dimension or mechanical property of the sample while it is subjected to a controlled temperature program.


The compact humidity generator (HUM-1) is connected to the TG-DTA for measurements under constant relative humidity water vapor atmosphere.


TMA/HUM measures change in dimension or mechanical property of a sample while subjected to a temperature regime under water vapor atmosphere with a constant relative humidity.

In TG-FTIR, gases evolved by volatilization or thermal decomposition are qualitatively analyzed, which allows you to track changes in the generated amount along with the temperature change.
