Abstract

This disclosure relates to an improved soft roll fuser com-prising a layer of Viton (trademark of E,I. du Pont) material adhered to a rigid core. The Viton layer is characterized by being relatively free of undesirable low to moderate molecular weight polymer fractions which are usually tacky or adhesive like. The foregoing is accomplished by post curing the Viton fuser roll at a temperature in excess of its normal operating temperature. For example, where the normal operating tempera-ture is about 370°F. the post cure is carried out at 395- 400°F. for a period of time (i.e., 2 24 hrs,) necessary for the polymer to stabilize, Stabilization refers to a condition where the Viton has a substantially constant weight loss during operation.
