Nylon 66 (Nylon 66) and nylon 6 (Nylon 6) water absorption:
Nylon 66: Nylon 66 is relatively absorbent and has high water absorbency. Performance may be degraded in humid environments.
Nylon 6: Nylon 6 has low water absorbency and is relatively less sensitive to humidity. This allows nylon 6 to remain relatively stable in wet conditions.
