CURABLE LIQUID SILICONE RUBBER COMPOSITION FOR FORMING A SEALING MEMBER AND SEALING MEMBER

摘要

A liquid silicone rubber composition comprising an alkenyl group-containing liquid organopolysiloxane, a reinforcing silica filler, an organohydrogenpolysiloxane, a platinum group catalyst, a liquid organopolysiloxane that is free of crosslinking groups and is compatible with the alkenyl group-containing liquid organopolysiloxane, and a liquid organopolysiloxane that is free of crosslinking groups and is incompatible with the alkenyl group-containing liquid organopolysiloxane, wherein the cured material therefrom has a JIS type A durometer hardness of 15 to 26 and a tensile stress at 100% elongation of 0.25 to 0.60 MPa. Also, a through hole-containing sealing member comprising this cured material.
