TGA decomposition information can
be used to predict the useful product
lifetimes of some polymeric
materials, such as the coatings for
electrical or telecommunication
cables. The sample is heated at
three or more different heating rates.
The use of the different heating
changes the time scale of the
decomposition event. The faster the
applied heating rate, the higher the
given decomposition temperature
becomes. This approach establishes
a link between time and temperature
for the polymer decomposition and
this information can be used to
model the decomposition kinetics.
