  • Patent number: 11472945
    Abstract: A slidable rubber material that has an amino-modified interfacial layer that does not affect the compression set. Although the slidable rubber material includes a rubber component such as a butyl rubber or halogenated butyl rubber etc. having the low-compression set, which contains a vulcanization agent such as a nitrogen/sulfur compound or a vulcanizing auxiliary agent, the rubber part is coated with a silicone rubber layer. The slidable rubber material exhibits a slidability and resists the detachment or elution of fine particles from the coating layer. A rubber component and a vulcanization agent; an interfacial modification layer that coats the rubber part and an amino-modified silicone compound is incorporated with surface molecules of the rubber part; and a layer that coats the interfacial modification and contains solid fine particles, an addition-type or condensation-type silicone rubber in which the particles are dispersed, and a curing catalyst for silicone rubber.
