| Photocopy documents may easily stick to ordinary PVC film because of migration of its ink and plasticizer contained in the PVC. Achilles has succeeded to disperse ultra fine particles of conductive material in the copy-safe coating and, by doing so, realized transparent ESD copy-safe coating, our ≪Achilles Seiden Crystal MS Table Mat≫ |
