    摘要: A novel thermally curable silicone rubber composition which is useful for the preparation of silicone rubber elastomers comprises diorganopoly-siloxane gum, a polyurethane elastomer having a softening point of not lower than 100.degree. C., a reinforcing filler, and an organic peroxide. The silicone rubber elastomers cured have an excellent resistance to mineral oils and organic solvents as well as other properties that are inherent in conventional silicone rubbers.

    摘要: Silicone rubber compositions consisting essentially of an organopolysiloxane containing in a molecule at least one linearly-linked cyclic siloxane unit and at least two alkenyl groups directly bonded to silicon atoms, an organohydrogenpolysiloxane, and a platinum catalyst. These compositions are cured to form solid elastomers which exhibit a very low permeability to water vapor, and are useful for enclosing electronic units.

    摘要: Silicone rubber compositions comprising a diorganopolysiloxane having localized vinyl group distribution, a silica filler with large specific surface area and a curing agent, e.g., an organic peroxide, the diorganopolysiloxane being prepared by the block-copolymerization of a hydroxy-endblocked diorganopolysiloxane without unsaturation and a chlorine-endblocked vinyl-containing diorganopolysiloxane by the dehydrochlorination-condensation. Cured elastomers from silicone rubber compositions have very much improved tear strength with the other properties being as good as those of the conventional silicone rubber elastomers.

    摘要: A method for cutting an ingot with a wire. The method includes the steps of moving a wire in a lengthwise direction and contacting an ingot with the moving wire. The method also includes the step of supplying an abrasive slurry containing cutting oil and abrasive particles having an average diameter of about 13 .mu.m to about 15 .mu.m to the ingot when the ingot and the wire are contacting. This results in the ingot being cut with the wire and abrasive particles.
