ABSTRACT:
A static-free, polymeric surface mat to prevent the accumulation of static charge, particularly in the packaging and handling of electronic components and devices, which mat comprises a nonconductive, synthetic-material layer with a top surface, optionally an adhesive layer on the bottom surface of the synthetic material, and a solid or foam layer of a conductive material, such as an open-cell urethane foam impregnated with finely-divided conductive particles, and a film-forming binder material to secure the particles uniformly onto the foam.
