TGA - thermogravimetric analysis.

The method of thermogravimetric analysis offers a multitude of advantages compared to the previously used methods – and the analysis of plastics, especially elastomers, is thereby decisively improved. Thermogravimetric analysis is also a reliable tool for investigating a large number of material properties in the research and development of new materials.

Are the properties of a rubber seal decisive for the function of a component?

If this is the case, we can precisely qualify the seal in terms of its composition and properties. In order to further increase the quality of the results in the qualification of elastomers, we supplement the analysis of FT-IR spectroscopy, DSC analysis and EDX analysis of fillers with a TGA (thermogravimetric analysis). This analysis technology provides additional information and rounds off the polymer characterization. With its precise temperature control, coupled with a highly sensitive weighing unit, it offers the possibility of tracking the degradation processes of plastics and elastomers and drawing conclusions about polymer blends, admixtures or polymer damage. Furthermore, moisture and plasticizer proportions, the content of organic fillers, e.g. carbon black or carbon fibers, as well as the proportion of inorganic fillers and reinforcing materials can be determined very precisely.
