Sealing Member and Its Manufacture |
摘要 |
A sealing member is obtained by molding a carbon fiber composite material (50) including a perfluoroelastomer (FFKM), and carbon nanofibers dispersed in the perfluoroelastomer, the carbon nanofibers having an average diameter of 0.4 to 230 nm. The perfluoroelastomer (FFKM) has a TR-10 value of −10° C. or less as measured by a temperature-retraction test (TR test) in accordance with JIS K 6261. The carbon fiber composite material (50) in a crosslinked form has a peak temperature of a loss tangent (tandelta) of −15° C. or less as measured by a dynamic viscoelasticity test.
