    • Provided is a silicone rubber composition for extrusion molding, including: (A) 100 parts by mass of an organopolysiloxane represented by an average composition formula (1): R1nSiO(4-n)/2 (in the formula, R1 represents identical or different, unsubstituted or substituted monovalent hydrocarbon groups, and n represents a positive number within a range from 1.95 to 2.04), (B) 0 to 50 parts by mass of a vinyl group-containing silicon compound, (C) 5 to 100 parts by mass of a reinforcing silica, and (D) an effective quantity of a curing agent, in which the vinyl group content relative to the combination of the components (A) through (D) is at least 1.0×10−4 mol/g. The composition yields a cured product for which the elastic modulus increases across a temperature range from 30 to 110° C. and which is therefore capable of reducing the temperature dependency of acrylic optical fibers. The composition is suitable for extrusion molding.
    • 提供一种挤出成型用硅橡胶组合物,其包含:(A)100质量份由平均组成式(1)表示的有机聚硅氧烷:R1nSiO(4-n)/ 2(式中,R1表示相同或不同的 ,未取代或取代的一价烃基,n表示1.95〜2.04的正数),(B)0〜50质量份含乙烯基的硅化合物,(C)5〜100质量份 的(D)有效量的固化剂,其中乙烯基含量相对于组分(A)至(D)的组合为至少1.0×10 -4 mol / g。 组合物产生固化产物,弹性模量在30至110℃的温度范围内增加,因此能够降低丙烯酸类光纤的温度依赖性。 该组合物适用于挤出成型。
