MILLABLE SILICONE RUBBER COMPOSITION EXCELLENT IN STRETCHING FATIGUE RESISTANCE AT HIGH TEMPERATURE

摘要

PROBLEM TO BE SOLVED: To provide a millable silicone rubber composition for vehicle vibration damping components, which composition is excellent in stretching fatigue resistance at high temperature.;SOLUTION: The millable silicone rubber composition for vehicle vibration damping components contains: 100 pts.mass of organopolysiloxane (a) having an alkenyl group; 10-100 pts.mass of reinforcing silica (b) having 50 m²/g specific surface area at the least; 0.005-0.5 pts.mass of one or more kinds of boron compounds (c) selected from boron oxide, boric acid, boric acid precursors, borate and partially-hydrolyzed borate; and a curing agent (d) for silicone rubber.;COPYRIGHT: (C)2014,JPO&INPIT
