More Information
Summary:Provided is a fluororubber molded article excellent not only in heat-resisting properties but also in mechanical properties at a high temperature. The molded article has a crosslinked fluororubber substance that is obtained by crosslinking a fluororubber composition containing a specific fluororubber (A) and carbon black (B), and the loss modulus E" of the crosslinked fluororubber substance is 400-6000 kPa inclusive in dynamic viscoelasticity test (measured temperature: 160 C, stretching strain: 1%, initial load: 157 cN, and frequency: 10 Hz).
