Thermogravimetric Analysis (TGA): determination of thermal stability/decomposition temperature/pyrolysis
In this analysis, a sample is placed in the thermogravimetric analyzer (TGA) and heated to a target temperature at a specific controlled heating rate while simultaneously measuring the sample weight.
The resulting weight change profile can be used to study of phenomena like decomposition, oxidation, desorption,...
At some point, the material will typically start to decompose/pyrolyze: the polymer chains start breaking into smaller fragments that outgass and cause a drop in the measured weight.
In this analysis, the weight change profile is recorded as a function of increasing temperature. A typical parameter that can be determined is the decomposition temperature which is often defined as the temperature at which 2% or 5% weight loss has occured.
Make sure to include information on your desired measurement conditions (stability criteria & parameters, temperature range, ramp speed,...) and the chemical nature (e.g. PP, PE, PET, PA,... preferably based a safety datasheet) of your polymer with your order. Extra costs may apply depending on the complexity and duration of your requested conditions.
