ABSTRACT:
A composition is described for use on the surface of separating members or devices used in separating superposed sheets. Good sheet separation is obtained without delamination of the sheets when microcellular elastomeric materials having a hardness of at least 25 durometer are used as the surface material of the sheet separating devices. The sheet separating devices having the described surface material, have utility as retarding rolls and abutment members in sheet feeders, such as in xerographic apparatus.
