Because shaft
seals may be asked to perform in extreme
heat or extreme cold, there are several important thermal
properties to consider when choosing an elastomeric compound
for the sealing lip. These include both high
and low temperature effects. The coefficient
of thermal expansion must also be considered
when selecting a case material.
