Effects of Temperature and Moisture

The E-modulus for PA 6 and 6.6 drops significantly with increasing levels of moisture (Fig. 7). Figure 8 illustrates the drop in tensile strength of nylon 6 at various moisture and temperature levels.

(PA12GC's E-modulus does not change notably with increasing moisture content - See Effects of Temperature Page Fig. 4.)
