The present invention provides a paper feed roll adapted for office machines which exhibits a high friction coefficient suitable for the conveyance of copying paper, printing paper, original, etc. and less abrasion. A process for the preparation of such a paper feed roll is also provided. Further, a silicone rubber composition suitable for the foregoing paper feed roll having an excellent formability to roll is provided. In particular, a novel silicone rubber-coated paper feed roll is provided, which is prepared from a silica-containing silicone rubber composition. The silicone rubber obtained by curing the silica-containing silicone rubber composition and composes the paper feed roll has an impact resilience of not less than 80% after curing as determined by JIS K6301, a permanent compression set of not more than 4% under a condition of 25% compression at 70.degree. C. for 22 hours and a 100% modulus of from 0.3 to 1.0 MPa. A novel silica-containing silicone rubber composition for use in a paper feed roll is also provided, which contains a diorganosiloxane represented by the following general formula as a silica treatment: ##STR1##

Paper feed roll, process for the preparation thereof and silicone rubber

A curable liquid composition containing a liquid polyorganosiloxane and carbon black whose specific surface area is at least 900 m.sup.2 /g and which are hollow-shell-shaped particles cures to a product having excellent electrical conductivity.

Electrically conductive curable liquid organopolysiloxane compositions

What is disclosed is a room-temperature vulcanizing flame-resistant silicone rubber composition which has triazole compounds added to it to enhance the self-extinguishing character of the flame resistant rubber.

Room-temperature-curing silicone rubber compositions

There is disclosed heat curable organopolysiloxane compositions which contain adhesion additives which are organosilicon compounds which contain an epoxy functional group and at least one alkyl group or low molecular weight alkenyl group or hydrogen atom bound to silicon.
