摘要:
A method for increasing the thermal conductivity of a fuser member for use in electrostatographic, including digital, apparatuses, by orienting anisotropic fillers in an elastomer layer in a manner wherein heat transfer is maximized in a radial or tangential direction of the fuser member. The fuser member may also contain other optional fillers and optional fluorocarbon powder fillers.

摘要:
There is disclosed a method for reusing a fuser member containing an outer layer having an original fusing surface that is deficient including: removing a portion of the thickness of the outer layer including the original fusing surface to create on the remaining outer layer a new fusing surface.
摘要:
A haloceramic material having integral, interpenetrating networks of haloelastomer, metal oxide, and optionally polyorganosiloxane forms highly advantageous seals such as gaskets, tapes, diaphragms, bearing, o-rings and the like. The haloceramer seals properties include a combination of thermal stability, chemical inertness and flexibility.
