Thermal Mechanical Analysis (TMA)

1. Introduction
2. Principle of TMA

This method is useful to determine  glass transition temperature (Tg). The principle is “Change in heat indicate the change in the dimensional behaviour of the polymer” i.e. heat flow rate of any textile material is depend upon the dimension of the material and the dimension of the material is depend upon the time and temperature.

TMA | Thermal Mechanical Analysis

It measures weight in micron/minut. crystalline temperature is always 40 to 60 no less than melting temperature.

3. Uses

TMA is used for checking flame retardancy, halogen oriented compound is best suitable for flame retardancy.
