<p><P>PROBLEM TO BE SOLVED: To provide a sealing member excellent in heat resistance, drug resistance and low-temperature property, and a method for producing the same. <P>SOLUTION: The sealing member is produced by shaping a carbon fiber composite material 50 in which carbon nanofiber having an average diameter of 0.4 nm to 230 nm is dispersed in a perfluoroelastomer (FFKM). The perfluoroelastomer (FFKM) has a TR-10 value of -10°C or lower as measured with a low-temperature elasticity recovery test (TR test) according to JIS K6261. The crosslinked product of the carbon fiber composite material 50 has a loss tangent (tanδ) peak temperature of -15°C or lower as measured with a dynamic viscoelasticity test. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
