| 摘要 |
Fluoropolyether rubber compositions comprising (A) a polyfluorodialkenyl compound terminated with alkenyl groups, (B) a perfluoropolyalkenyl compound or a polyalkenylsiloxane compound, (C) a fluorine-modified organosilicon compound having at least two SiH groups, (D) a platinum group compound, and (E) hydrophobic silica powder are suited for injection molding, typically by LIMS. Rubber parts resulting from curing have heat resistance, chemical resistance, solvent resistance, low-temperature properties, high hardness and high strength.
