FIBC Electrostatic Types
Type B FIBCs
Similar to Type A FIBCs in that they are made from plain polypropylene or other non-conductive material. The difference is that Type B bulk bags are made from materials that have a low breakdown voltage to prevent the occurrence of highly energetic, and dangerous propagating discharges (PBD). Although Type B FIBCs can prevent PBD they cannot be considered antistatic because they do not dissipate electrostatic charge and so normal brush discharges can still occur, which can ignite flammable solvent vapours.
Type C FIBCs
Also known as conductive or groundable FIBC. Commonly made from non-conductive polypropylene interwoven with conducting yarns, normally in a grid pattern. The interconnection of conductive yarns and the connection to ground or earth are critical to the safe use of Type C FIBCs. As with any manual operation, ensuring interconnection and grounding of Type C FIBCs is subject to human error.
Type D FIBCs
Made from static protective fabric designed to safely prevent the occurrence of incendiary sparks, brush discharges and propogating brush discharges, without the need for a connection from the bulk bag to the ground or earth. As CROHMIQ Type D FIBCs protect against incendiary sparks, brush discharges and propagating brush discharges, CROHMIQ can be used safely to package combustible products and for handling products in combustible and flammable environments.
