Title:
RUBBER CROSSLINKED PRODUCT AND METHOD FOR MANUFACTURING FOR SAME
Document Type and Number:
WIPO Patent Application WO/2018/225789
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a rubber crosslinked product capable of improving the long-term sealing properties of a sealing member in high-temperature and pressure environments. This rubber crosslinked product is obtained by crosslinking a crosslinkable rubber composition that contains a fluororubber, carbon black, carbon nanotubes, and an organic peroxide crosslinking agent. The rubber crosslinked product has a 50% modulus of at least 5 MPa, compression set (230°C, 500 hours) of no more than 80%, and a rate of change of -10% to 10% in elongation at break before and after a heat aging test (230°C, 72 hours).
