    摘要: A thermoplastic, moldable, millable, extrudable composition of matter involving at least three polymeric components: a fluoroelastomer, an ETFE (ethylene/tetrafluoroethylene alternating copolymer, which may optionally contain one or more comonomers in minor amounts to alter crystallinity and melting temperature) fluoroplastic, and a block fluoropolymer containing at least one fluoroelastomer block and at least one ETFE block. The fluoroelastomer component and optionally the fluoroelastomer portion of the block fluoropolymer are crosslinked in a dynamic vulcanization process. Also disclosed are multilayer articles in which the aforesaid fluoro-TPV is adhered to an ETFE plastic layer. These bonded multilayer objects may include injection-molded parts that are either co-injected with both ETFE and fluoro-TPV layers, or insert molding jobs in which a previously molded ETFE insert is placed into a mold and surrounded by fluoro-TPV; and also multilayer co-extruded products such as hoses in which a fluoro-TPV layer is extruded against an ETFE layer.

    摘要: In a scroll compressor, a thrust ring is mounted between a movable-side flat plate part of a movable scroll and a housing. An upper surface of the thrust ring slides relative to a lower surface of the movable-side flat plate part and supports a thrust load from the movable scroll. A resinous coating is formed on the upper surface of the thrust ring which slides relative to the movable-side flat plate part. The resinous coating is composed primarily of fluorocarbon resin and polyamide-imide resin. The component percentage of the polyamide-imide resin in the primary component of the resinous coating is set, such that it is not less than 65% by mass nor more than 85% by mass.
