<p>PURPOSE:To provide electrically conductive liquid silicone rubber compsn. which can easily be molded by extrusion, consisting of diorganopolysiloxane, liquid organohydrogenopolysiloxane, carbon black, electrically conducting fiber and a catalyst for addition reaction. CONSTITUTION:There is provided electrically conductive liquid silicone rubber compsn. for extrusion molding consisting of (A) 100pts.wt. of diorganopolysiloxane having at least two alkenyl gp. bonded to silocon atom per molecule and a viscosity of from 100 to 100000 centistokes at 25 deg.C, (B) liquid organohydrogenopolysiloxane having at least two hydrogen atoms bonded to silicon atom per molecule (the sum of alkenyl gp. of (A) bonded to Si per molecule and hydrogen atoms of (B) bonded to Si per molecule, is 5 or more) in such a proportion as to give a mole ratio of H (bonded to Si) to alkenyl (bonded to Si) of from 0.5:1 to 10:1, (C) from 3 to 30pts.wt. of carbon black, (D) from 1 to 50pts.wt. of electrically conducting fiber and (E) a catalyst for addition reaction.</p> |
