Typically, several of the belts, rolls and paddles used In autornatic electrostatographic reproducing apparatus are required to be conductive in order to dissipate heat or 5tatic electricity. The typical elastomeric materials that have been previously available on the market to form such belts, rolls and paddles, required the addition of high filler loadings to render them conductive for that purpose thereby rendering the materials difficult to rnoId or otherwise process into the suitable shape. We herewith propose use of a new family of conductive liquid elastomers which can be readily processed with good heat conduction and electrical dissipating properties. The genera1 class of materials comprise, liquid poiydirnethyl siloxanes having when cured a Shore R hardness in the range of 30 - 70. Typical materials available which are capable of being liquid injection molded or vertically extruded include the GE conductive liquid elastomers SLE 3030A and SLE 303013 as well as Dow Corning 595 GP590. Both of these materials are available in a tow component supply, one including the base polymer and the other a suitable cross-linking agent and catalyst required which once mixed together may be autornatically fed into either a vertical extruder or liquid injection mold. The cconorny 01 such operation readily lends itself to the production of large volumes of relatively inexpensive parts.
