We have specially designed antistatic Big Bags Type C and D with X-static TM technology, which occurs during the filling and unloading of Big Bags static electricity that can lead to explosion of flammable gases, vapours and dust. It is vitally important in the industry to deal with static electricity safely and the occurrence of explosions using antistatic FIBC/BB. These bags comply with the international standard IEC 61340-4-4.
Type C: Woven conductive wires connected to all parts of the FIBC and to an earth wiring with a resistance of less than 10 to the 8th ohm. If the inside or outside is coated, the breakdown voltage must be <6 kV in order to prevent the spreading of brush discharges. (Zones 1, 2, 21 and 22)
Type D: Cloth with a conductive tissue system and/or special coating. There is no interconnection with all parts of the FIBC and there is no grounding. These FIBCs are not conductive but give a charge to the environment via the corona effect. This FIBC should not be grounded. However, the environment, machinery and personnel must be completely grounded. And the humidity must comply with restrictions. (Zones (1), 2.22)
