Nylon and moisture: the real story behind the effects of drying resin and conditioning molded parts on final properties

摘要

The influence of absorbed moisture on the performance of nylon products is well documented. Similarly, the effects of excess moisture on the processing of nylon are well established. But confusion often arises in the processing community regarding the reasons for the brittle behavior of nylon parts. This paper is designed to follow the role of moisture from the pellet through to the conditioned part and separate the fact from the fiction regarding the effects of moisture on nylon properties.
