GO-MA/2K ESD

Polyester film with matt and conductive coating on the front side. The specific surface resistance of 10⁶ to 10⁹ ohm/square (DIN 53482) allows slow release without lightning discharge. Reverse side with ink receptive coating. Material is available with a thickness of 0.13 or 0.18 mm.

Available in sheets and rolls. Sheets available in standard packing unit or on demand. All sheets are equipped with interleaving paper as standard. Options such as self-adhesive protective film is available but will be an additional cost.
