All polyamides have a tendency to absorb moisture to a greater or lesser extent. For this reason, when using these materials, attention should be paid to their technical data in the dry state and after moisture absorption. In practice, moisture acts as a softening agent (plasticizer) in polyamides and causes a decrease in the tensile modulus and an increase in impact resistance. Given the sensitivity of polyamides to moisture absorption, these materials require dehumidification before the injection process. If the dehumidification process is not carried out properly, the undesirable effect of moisture streaks is observed on the surface of the manufactured parts. In addition, due to a point increase in temperature in the mold and the effect of water in oxidation, the manufactured parts will have weaker mechanical properties due to material degradation. Therefore, given the importance of the amount of moisture absorbed by polyamides, it is recommended that they be stored in a covered environment with a relative temperature of 15-20 degrees Celsius and on flat surfaces in order to maintain their mechanical properties.
