  • Silicone rubber composition and silicone rubber crosslinked body
    Patent number: 10364353
    Abstract: Provided are a silicone rubber composition that is excellent in storage stability and crosslinking reactivity, and a silicone rubber crosslinked body made from the silicone rubber composition. The silicone rubber composition contains (a) an organopolysiloxane, (b) a crosslinking agent, and (c) a microcapsule type catalyst that is made of microparticles of a resin and a crosslinking catalyst encapsulated in the microcapsules, wherein the solubility parameter of the resin of (c) is 7.9 or higher, a thermal conductivity of 0.16 W/m·K or higher, and a glasstransition temperature of 40 to 145 degrees C. The silicone rubber crosslinked body is made of a crosslinked product of the above-described silicone rubber composition.

  • SILICONE RUBBER COMPOSITION AND SILICONE RUBBER CROSS-LINKED BODY, AND INTEGRALLY MOLDED BODY AND METHOD FOR PRODUCING INTEGRALLY MOLDED BODY
    Publication number: 20180346723
    Abstract: Provided is a silicone rubber composition that has excellent storage stability and an improved post-curing compression set, and a silicone rubber cross-linked body made from the silicone rubber composition. A silicone rubber composition contains (a) an organopolysiloxane, (b) a cross-linking agent, and (c) a microcapsule type catalyst that is made from resin microparticles encapsulating a cross-linking catalyst, wherein the resin of (c) is one of a thermosetting resin that is thermally cured in the presence of the cross-linking catalyst and a thermosetting resin that is thermally cured in the absence of the cross-linking catalyst.
