A semiconducting component for an electrographic device, comprising a crosslinked body obtained by crosslinking a copolymer containing 9.9 to 39.9% by mole of structural units (a) originating from an epihalohydrin, 60 to 90% by mole of structural units (b) originating from an alkylene oxide, and 0.1 to 10% by mole of structural units (c) originating from a cyclic ether monomer having a (meth)acryloyl or alkoxysilyl group with use of reactivity of the structural units originating from the cyclic ether monomer having a (meth)acryloyl or alkoxysilyl group.

Semiconducting component for electrographic device

A composition for vulcanizing adhesion, comprises a rubber (a), at least one compound (b) selected from the group consisting of salts of 1,8-diazabicyclo(5.4.0) undecene-7, salts of 1,5-diazabicyclo(4.3.0)-nonene-5, 1,8-diazabicyclo(5.4.0) undecene-7, and 1,5-diazabicyclo(4.3.0)-nonene-5, and at least one water-carrying substance (c) selected from water-absorbed substances and hydrated substances.

Composition for vulcanizing adhesion

Disclosed is a vulcanized rubber laminate, wherein a thermoplastic resin layer and an unvulcanized epichlorohydrin rubber composition layer containing a specific maleimide compound, vulcanizing agent, and acid acceptor are heated and bonded. Specifically disclosed is a laminate configured by heating and bonding an unvulcanized epichlorohydrin rubber composition layer (A) and a thermoplastic resin (B), wherein the unvulcanized epichlorohydrin rubber composition contains: an epichlorohydrin rubber (a), a compound containing one or more maleimide group within the molecule (b), a vulcanizing agent (c), and an acid acceptor (d).

Rubber-resin laminate

The present invention provides a rubber composition, which realizes low hardness and low compression set while maintaining semi-conductivity, and a vulcanizate thereof. Also the rubber composition can be obtained by blending an epichlorohydrin-based rubber having satisfactory semi-conductivity and an acrylonitrile-butadiene-based rubber as a reactive plasticizer, and also blending zinc oxide, a thiuram-based compound and a quinoxaline-based compound.

Semi-conductive rubber composition and vulcanizate thereof

A composition for a semiconductive rubber, comprising an epichlorohydrin-based rubber (a), an ethylene oxide-modified (meth)acrylate (b), and at least one kind of a crosslinking agent (c) selected from the group consisting of a sulfur-based crosslinking agent, a quinoxaline-based crosslinking agent and a triazine-based crosslinking agent.
