Thermogravimetric analysis (TGA)
TGA is a technique that measures the change in weight (Δm) by means of a very sensitive microbalance as a function of temperature and time. The instrument is very sensitive and has high precision and accuracy in terms of temperature and weight recording. Most often, a loss of weight occurs when the temperature increases, where different components are gradually lost. Here you will get important information about the composition and thermal stability of the materials. Below are some examples of parameters that we at TermoLab can help to investigate.
Compositional analysis
The amount of the different constituents of a polymer matrix is directly determinative of how good or bad the material will be for a particular product. With the help of TGA there is a possibility of quantifying the constituents such as base polymer, fillers, plasticizers, etc. This type of test is also important to continuously monitor both raw materials and products to ensure quality.
Degradation processes
How the polymer is degraded and at what temperatures can be valuable to know depending on which application a product is to be used for. The degradation also provides a lot of information about the structure and properties of the polymer.
Thermal stability
The thermal stability of a polymer depends on a variety of parameters, including concentration and type of stabilizing additives.
Moisture content
Certain polymers preferably absorb moisture, which gives them altered properties. For several reasons, moisture is an important parameter to control. Using the TGA, you can determine the amount of moisture in polymers.
Ash content
Ash content or the remaining after a total combustion with TGA can be important information in many respects. You can also identify the remainder using FT-IR.
