Abstract
A thermoconductive liquid silicone rubber composition is provided for fixing rolls. The composition is capable of producing silicone rubber of superior thermal conductivity and small compression set after curing. The thermoconductive liquid silicone rubber composition contains (A) a diorganopolysiloxane with at least two silicon bonded alkenyl groups per molecule, (B) an alumina powder with an average particle size not more than 10 &mgr;m and an ignition loss of not more than 0.15 weight percent, (C) an organohydrogenpolysiloxane having at least two silicon bonded hydrogen atoms per molecule, and (D) a platinum catalyst. Fluororesin coated fixing rolls can be fabricated by providing a fluororesin layer on the peripheral surface of a roll shaft, with the silicone rubber layer interposed between it and the surface.
