ELECTRICALLY CONDUCTIVE SILICONE RUBBER COMPOSITION AND CURED PRODUCT THEREOF

摘要

PURPOSE:To obtain a composition having excellent moldability and giving a cured material having excellent physical properties and high electrical conductivity, at a low cost, by compounding a silicone rubber compound with spherical silicone particles, a conductivity-imparting metallic agent, a curing agent and an organic silicon compound. CONSTITUTION:The objective composition is produced by compounding (A) 100 pts.wt. of a diorganopolysiloxane having an average composition of formula I (R<1> is univalent hydrocarbon group; (n) is 1.95-2.05), (B) 5-100 pts.wt. of spherical silicone elastomer particles having an average particle diameter of 0.1-50mum, (C) 100-1,200 pts.wt. of a conductivity-imparting metallic agent, (D) 0-20 pts.wt. of a liquid organic silicon compound having an average composition of formula II (R<2> is methyl or lower alkenyl; R<3> is phenyl or 3-10C alkyl; X is H, OH, etc.; 0<=a<4; 0
