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.

While enjoying some freshly served tasty wines on a terrace on the slopes of Villány or Eger, probably you do not think of the journey the grapes have been making from the wine ranks to the glass. The bottle has probably been conveyed during filling, during packing, and during sales.  But it is very likely that the very first occasion the product met with conveyor belts took place at the time of harvest.
