Semi-Conductive Polyurethane in EP Systems: A Comparison of “Dynamic” to “Static” Volume Resistivity Testing of Rollers
Abstract:This paper explores testing of semi-conductive polyurethane materials as they apply to use in EP systems. A method for measurement of volume resistivity and Electrical characteristics over time are explored in detail. A common formula for specifying resistivity is explained, as is the effect of dynamic measurement vs. static measurement. This paper is an extension of the paper presented at IS&T NIP-17 which explained basic manufacture and specification of Ionic conductive doped polyurethane as used in EP systems.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
