- Engineering Notes
As Duratron® PAI has a relatively high moisture absorption rate (see Figure 24), parts used in high-temperature service or made to tight tolerances should be kept dry prior to installation. Thermal shock resulting in deformation can occur if moisture-laden parts are rapidly exposed to temperatures above 400°F (205°C).
