Abstract
Thermal aging processes in polyethylene
terephthalate film (PETP) were investigated in three laboratories in
France, Finland and Norway, using both sensitive analytical methods to
measure the aging reaction rates and physical aging tests of
conventional nature. The known non-linearity [9] of the thermal
endurance graph of this material was confirmed at ca. 180°C. In spite of
this, the behavior of the material was predictable, especially when the
EAP test method [3] was applied. Analytical methods combined with
suitable physical aging tests were shown to be rapid tools for
investigating the long term thermal endurance of materials in short
time.
