Another example of the ability of the
Auto Stepwise approach to provide
outstanding separation of overlapping
weight loss events is for tire
elastomers. These elastomers
consist of a blend of polymer, oil
extender, carbon black and fillers.
It is difficult to separate out the oil
from the polymer using standard
TGA since the two events severely
overlap. However, with the Auto
Stepwise approach, all of the
components in a tire elastomer can
be clearly identified as is shown in
Figure 6. This information is
valuable for the production of an
automotive tire with the desired end
use and long term properties.
