VERFAHREN ZUR HERSTELLUNG EINES MATERIALS MIT ELEKTROSTATISCHER AUFLADUNGSMINDERUNG

摘要

The present invention relates to compositions comprising conductive particles and one or more polymers, particularly acid copolymer resins or derived ionomers, which can be extruded or heat formed into films or articles. More specifically, the method of the present invention is directed to a novel, non-uniform heating process, wherein the edge portions of a material is heated about 3-50 degrees Celsius hotter than the center or middle portions of the article or film during fabrication to thereby provide improved and substantially uniform electrostatic dissipative ("ESD") properties.
