Abstract

The present invention relates to fusing devices in electrostatographic copying machines. It is known to make the end caps on heated fuser rolls with an insulating plastic material. Such plastic materials must be abl% to withstand a load of several hundred pounds and to resist temperatures of 450 F or higher. In accordance with the present invention, such fuser roll end caps are to be made from: a glass filled epoxy material available from the Fiberite Company under its trade designation E260H; a glass filled epoxy available from the Gulf Corporation under its tradename Lytex 1445; or a glass filled polyimide available from the Fiberite Company under its trade designation PI720. These materials all performed very well in heat aging tests conducted at 450 F, with very little weight loss to indicate stability of the material at the test condition.
