Beth yw'r gwahaniaeth rhwng deunyddiau dargludol a deunyddiau dissipative mewn rheoli amddiffyn electrostatig
Materials are either conductors or non-conductors. Non-conductive materials, also known as insulators, have a resistance > 1 x 10 11 ohms. Dissipative material is the part of conductive material, >1 x 10 4 ohms<10 11 ohms, which has the advantage of static control and can discharge static charge to the ground more slowly. From the perspective of static electricity prevention and control, conductive materials refer to materials <10 4 ohms, except for electrostatic floors with special definitions.
