The insulating properties of bakelite panels can be affected by humidity

The insulation performance of electric wood panels is affected by humidity.
Electric wood panels can maintain good insulation performance in dry environments. Because its main component, phenolic resin, is a high molecular weight polymer with good electrical insulation properties, its internal chemical bonds and molecular structure can prevent the movement of electrons, thereby providing insulation.
However, when in a high humidity environment, the situation is different. An increase in humidity means an increase in water molecules in the air, which will adsorb onto the surface of the electric board and may penetrate into the interior of the material. Due to water being a weak electrolyte containing freely moving ions, these ions increase the conductivity of the electric board and reduce its insulation resistance. Moreover, prolonged exposure to high humidity environments may lead to hydrolysis reactions in the plywood, causing the chemical bonds of the phenolic resin to break and further damaging its insulation properties. However, the electric wood board itself has a certain degree of moisture resistance, and in general humidity environments, the decrease in insulation performance is relatively small.
