• Determination of Ash ContentThe ash is a measure of the mineral oxide content on a weight basis. Thermogravimetric analysis (TGA) in an oxidative atmosphere is a well-proven method to determine the inorganic residue, commonly referred to ash, in organic materials such as polymers, rubbers, etc. Therefore, the TGA measurement will identify if a material is filled and calculates the total filler content.ash content

Determination of the Glass Fiber Content in PA66

Polyamide 66 is a thermoplastic polymer which is used for a wide variety of technical parts.
The stiffness of the PA66 can be increased by suitable fillers such as glass fibers. TGA allows for determination of not only the Decomposition reactionA decomposition reaction is a thermally induced reaction of a chemical compound forming solid and/or gaseous products. decomposition of the polymer, but also the precise glass fiber content (residual mass 20.2% at 989°C).
After switching from nitrogen to synthetic air, the TGA curve also shows the content of pyrolytic soot and Added Carbon BlackCarbon black acts as a reinforcing filler in tires and other rubber products.

The c- DTA^® peak exhibits the melting peak of PA66 at 260°C (red curve).
