摘要： One embodiment of the present invention relates to an elastomer composition, a sealing material, or a method for producing a sealing material, in which the elastomer composition includes a crosslinkable fluoroelastomer (A) other than a perfluoroelastomer, an ethylenically unsaturated bond-containing compound (B), a crosslinking agent (C), and a crosslinking aid (D), the ethylenically unsaturated bond-containing compound (B) contains at least one selected from compounds having a perfluoro skeleton having an ethylenically unsaturated bond and compounds having a siloxane skeleton having an ethylenically unsaturated bond, and a mass ratio of a content of the crosslinking aid (D) to the crosslinking agent (C) is 5 or more.

摘要： One embodiment of the present invention relates to an elastomer composition, a sealing material, or a method for producing a sealing material, in which the elastomer composition includes a crosslinkable fluoroelastomer (A) [provided that the elastomer (A) is a compound having no hydrosilyl group] and a composition (B) that contains at least one ethylenically unsaturated bond-containing compound selected from compounds having a perfluoro skeleton having an ethylenically unsaturated bond [provided that the compounds are compounds other than the elastomer (A)] and compounds having a siloxane skeleton having an ethylenically unsaturated bond, the composition (B) having a minimum torque (ML) at 60°C of 0.5 kgf·cm or more as measured with a CURELASTOMETER.
