Polyamide is a hygroscopic plastic with relatively high water absorption. To ensure that the insulation does not break during processing, the polyamide-insulated cable lugs must be kept conditioned until they are processed. Always store the insulated cable lugs in a closed poly bag. The ideal storage conditions are +23 °C and 50 % relative humidity. After opening the packaging, the cable lugs should be processed quickly.

For optimum processing, the polyamide insulation should have a water content of approx. 2.5 to 4 %. When cold, from about -2 °C, the water content in the polyamide is also lost within the poly bags. This results in a hardening of the insulation. In order to restore the required water content, the cable lugs must be re-conditioned accordingly before processing..
