FLUORORUBBER COMPOSITION |
| 摘要 |
Provided is a fluororubber composition capable of providing a crosslinked fluororubber article that exhibits not only heat resistance, but also excellent mechanical properties at high temperatures. The fluororubber composition includes a fluororubber (A), a carbon black (B), and an aromatic petroleum resin (E), and the fluororubber composition has a difference δG′ (G′ (1%)−G′ (100%)) of not lower than 120 kPa and not higher than 3,000 kPa, where G′ (1%) denotes a shear modulus at a dynamic strain of 1%, G′ (100%) denotes a shear modulus at a dynamic strain of 100%, and G′ (1%) and G′ (100%) are determined by a dynamic viscoelasticity test carried out on an unvulcanised rubber with a rubber process analyzer (RPA) in a condition that the measurement frequency is 1 Hz and the measurement temperature is 100° C. |

1. A fluororubber composition comprising:
a fluororubber (A); a carbon black (B); and an aromatic petroleum resin (E), the fluororubber composition has a difference δG′ (G′ (1%)−G′ (100%)) of not lower than 120 kPa and not higher than 3,000 kPa, where G′ (1%) denotes a shear modulus at a dynamic strain of 1%, G′ (100%) denotes a shear modulus at a dynamic strain of 100%, and G′ (1%) and G′ (100%) are determined by a dynamic viscoelasticity test carried out on an unvulcanised rubber with a rubber process analyzer (RPA) in a condition that the measurement frequency is 1 Hz and the measurement temperature is 100° C. |
