While TMA can be performed on virtually any polymeric material, it is most effective on samples with a high coefficient of thermal expansion.

In addition, measurements of internal friction, bulk density, and wall friction on various wall surfaces are included. Our astm e831 have knowledge in experience in a wide variety of industries and applications, and are involved in a diverse group of standards and materials organizations.

Element has highly trained polymer experts throughout the United States and in Europe. E Terminology Relating to Thermophysical Properties. As the samples gets warmer, the astm e831 expands and the rod changes positions. Send us a request Wilton UK: The test method may be used at lower or negative expansion levels with decreased accuracy and precision see Section No other units of measurement are included in astm e831 standard.
