<p><P>PROBLEM TO BE SOLVED: To provide a silicone rubber composition for extrusion molding which forms a cured product reducing the temperature dependency of an acrylic optical fiber sensor due to the rise in elastic modulus at 30-110°C and enables extrusion molding. <P>SOLUTION: The silicone rubber composition for extrusion molding comprises 100 pts.mass organopolysiloxane (A) represented by the average composition formula: R<SP>1</SP><SB>n</SB>SiO<SB>(4-n)/2</SB>(wherein R<SP>1</SP>is the same or different nonsubstituted or substituted monovalent hydrocarbon group and n is a positive number of 1.95-2.04), 0-50 pts.mass vinyl group-containing silicon compound (B), 5-100 pts.mass reinforcing silica (C), and an effective amount of a curing agent (D), and has a vinyl group content, based on the sum of components (A) to (D), of not less than 1.0×10<SP>-4</SP>mol/g. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
