NRD Static Control LLC

The amount of moisture present in the air can affect the conductivity of insulating materials and their ability to hold a static charge. The higher the moisture content in the air, the more conductive a material becomes. Conversely, the dryer the air is, the more insulative the material becomes allowing it to hold a greater charge. Although controlling humidity can be helpful, it is a very slow process and often does not afford sufficient reduction in charge to be a complete solution to the problems caused by static charging.
