Material properties of plastics
General material properties, such as density and ash content, are required for the allocation determination of plastic materials and they help in classifying the examination results.
The humidity and water absorption have a great influence on a number of properties in particular of polyamides.
Thermo gravimetric analysis (TGA) is an examination method that is more specific than the ash determination. The weight reduction of the specimens is monitored depending on the test temperature and therefore the mass percentage of individual components, glass fibres and fillers can be determined partially.
