ElectroStatic Dissipative (ESD) and AntiStatic (AS) Conveyor-belts
Most conveyor belts are made of certain polymers with high surface resistance. This provides certain insulation that does not allow electrostatic charge and discharge. Those belts are called insulated or conductive if they have a surface resistance (resistivity factor) higher than 1012 ohm/sqm. The issue with such belts is that the discharge of static build-up electricity during the conveying may damage the conveyed products or may even cause other damages during the manufacturing process. Conveyor belts used in certain applications may not be charged electrostatically.
