FLUORORUBBER MOLDED ARTICLE

摘要

The present invention provides a fluororubber formed product having excellent heat resistance and excellent mechanical properties at high temperatures. The formed product comprises a cross-linked fluororubber product obtainable by cross-linking a fluororubber composition containing a fluororubber (A) and a carbon black (B), the fluororubber (A) being a vinylidene fluoride fluororubber including 48 to 88 mol% of a structural unit derived from vinylidene fluoride and 0 to 10 mol% of a structural unit derived from tetrafluoroethylene relative to the total amount 100 mol% of structural units derived from all monomer components, the cross-linked fluororubber product having a loss modulus E" of 400 kPa or higher and 6,000 kPa or lower determined by a dynamic viscoelasticity test (measurement temperature: 160°C, tensile strain: 1%, initial force: 157 cN, and frequency: 10 Hz).
