CURABLE SILICONE RUBBER-BASED COMPOSITION AND MEASUREMENT METHOD FOR CURABLE SILICONE RUBBER-BASED COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a curable silicone rubber-based composition from which silicone rubber excellent in tensile strength and tear strength is obtainable, since the correlation between the aggregation structure of an inorganic filler such as silica microparticles in a silicone rubber, and tensile strength and tear strength has not been elucidated.;SOLUTION: There is provided the curable silicone rubber-based composition of claim 1, in which the aggregate size of the inorganic filler is 20-25 nm when it is not drawn, as determined by synchrotron X-ray diffraction measurement, and the maximum value of the orientation coefficient of the curable silicone rubber-based composition when it is drawn, which can be determined by synchrotron X-ray diffraction measurement is 0.25 to 0.35.;COPYRIGHT: (C)2013,JPO&INPIT
