Thermomechanical Analyzer TMA-60 Series

Importance of Topic

Thermomechanical analysis is a key technique for evaluating dimensional changes and mechanical responses of materials under controlled temperature programs. It enables detailed insights into phase transitions, thermal expansion, contraction, polymerization, crystallization, and stress generation in diverse materials such as polymers, metals, ceramics, and composite films.

Objectives and Overview

The aim of this application note is to present the features and capabilities of the Shimadzu TMA-60 series analyzers. It compares two models, the TMA-60 for absolute expansion and penetration measurements and the TMA-60H for high accuracy differential expansion, and highlights their operational modes and performance in various material testing scenarios.

Methodology and Instrumentation Used

• TMA-60 series analyzers capable of tension, expansion, and penetration modes
