SILICONE MATERIAL CAPABLE OF ADDITION-CROSSLINKING, ITS PRODUCTION AND USE, AND SILICONE ELASTOMER OBTAINED THEREFROM AND USE OF THE ELASTOMER

摘要

PROBLEM TO BE SOLVED: To provide a silicone material capable of addition-crosslinking, which affords a silicone elastomer whose tear resistance and elongation at break are high at the same time, by crosslinking.;SOLUTION: The silicone material contains (A) 100 pts.mass of a vinyl-terminated polydiorganosiloxane having 5,000-1,000,000 mPa s viscosity, (B) 0.1-50 pts.mass of a polyorganosiloxane having 200-1,000,000 mPa s viscosity, (C) 1-150 pts.mass of a polyorganosiloxane having at least 2,000,000 mPa s viscosity, (D) an SiH-functional crosslinking agent, (E) a hydrosilylation catalyst and (F) 0-90 pts.mass of a filler having at least 50 m²/g specific surface area.;COPYRIGHT: (C)2007,JPO&INPIT
