1. Appreciate the weather and living conditions of your room

Before choosing your material, you need to determine the life and duration of your part. Indeed, even more than the mechanical stresses that the part may have to withstand, it's the "chemical" degradations that will deteriorate the electrical performance of the materials. So start by determining the expected service life, and the types and frequencies of electrical and mechanical stress on your part. For example, don't choose a rapidly biodegrading material if you plan to leave the room outdoors, exposed to light and humidity. Similarly, in the case of a control box for outdoor use, we advise against choosing materials whose surface oxidizes rapidly. Tracking currents could form and endanger the user, before the decreasing transverse strength of the material damages the housing.
