A sealing material including a water-resistant sheet, wherein the water-resistant sheet includes layered clay minerals having a thickness of 0.5 nm to 800 nm. A sealing material including a sheet, wherein the sheet includes modified layered clay minerals in which at least a portion of a first cation between the interlayer of swellable layered clay minerals is ion-exchanged with a second cation, in a first cation being one or more selected from Na.sup.+ and Li.sup.+. A sealing material including a sheet, wherein the sheet includes layered clay minerals having a thickness of 0.5 nm to 800 nm, and having one or more selected from K.sup.+, Ba.sup.2+ and Pb.sup.2+ are contained in at least a portion in an interlayer of the clay minerals.

A composite article includes a lattice and an elastomeric section. The lattice includes a plurality of members that form an open-mesh frame defining a plurality of voids between the adjacent members of the frame. The elastomeric section is formed of an elastomer that is disposed about the lattice and within the voids of the lattice. The composite article may be a circular gasket, a gasket with a grip, a rectangular gasket, a vessel cap, a flask stand, and a handle for a hand tool.

A ring dam, fitting between a fluid container and a housing for the fluid container, may include an extruded Polyethylene (EPE) foam having an Ethylene-Vinyl Acetate (EVA) additive.

A housing is made sealable even when the rigidity of a frame member and a cover member is not high. In an EFEM, a pressure difference having a predetermined value or less exists between an internal space of a housing and an external space of the housing. The housing includes a frame member assembled so as to form an opening, a cover member attached to the frame member so as to cover the opening, and a seal member sandwiched between the frame member and the cover member and configured to extend so as to surround the opening. The frame member and the cover member are formed of a sheet metal. The seal member is an elastic member having a hollow cross section orthogonal to an extension direction of the seal member.

A gasket is provided which is configured so that a gasket body is easily separated from a carrier film and the positional shift of the gasket body in stacking can be prevented. The gasket has a combination of a gasket body which contains only a rubber-like elastic body and which, in order to seal a gap between one member and the other member, is mounted in the other member and a carrier film separably stuck to one surface side in the thickness direction of the gasket body, in which an engagement portion is formed in the other surface in the thickness direction of the gasket body at a position corresponding to a portion to be engaged formed in the other member, and the gasket body is mounted in the other member by engagement of the engagement portion and the portion to be engaged.

An integral multilayer joint seal. Layers of foam, layered co-planar to the adjacent surface, are interspersed with a barrier layer which extends beyond the foam layers to provide a protective surface, a surface for attachment atop adjacent substrates, or a connecting tab for use with adjacent joint seals. The foam layers may be uncompressed or partially compressed at the time of joint formation and may be composed of open or closed, or hybrid, cell foam. The foam may be impregnated with a fire retardant or may be composed of a fire retardant material, if desired. The barrier may have a tensile strength greater than the adjacent foam. The joint seal may have an elastomer, such as silicone, at its top and/or bottom, and may even include an elastomer layer within or about the barrier.

To effectively prevent a breakage of a plate when a gasket body formed of a rubber-like elastic material is integrally molded at both faces of the plate formed of a brittle material such as carbon. In order to attain this object, there is provided a method of manufacturing a plate-integrated gasket in which a gasket body formed of a rubber-like elastic material is integrally formed at both sides of a portion along a peripheral edge of a plate in the thickness direction, where an area located between gasket molding cavities defined by clamping the plate between split dies of a metal mold in the plate is formed to be a relatively thick portion at a position, facing an opening of a gate through which a molding material is injected into the cavities, and in the vicinity thereof.

The sealing method is for sealing between: a rear surface of a first component which is a composite material containing a reinforcing fiber and a resin; and a front surface of a second component facing the rear surface of the first component. The sealing method includes: a step (ST03) in which a molded body is placed at a corner between the front surface and an end surface of the first component, with a first sealing material interposed therebetween; and a step (ST06) in which a second sealing material is applied from the molded body up to the front surface of the second component.

An expansion joint seal proving a flexible barrier therethrough in a concave shape with a first body of compressible foam on one side and a second body of compressible foam on the other side, where the barrier extends laterally from the first body and second body and may be used to protect the sides of the expansion joint seal or may be used to provide contact on the surface of each adjacent substrate.

A non-metallic flange isolation gasket kit sealing flanged pipeline connections and flanged vessel connections while providing electrical isolation protection between flanges suited for high-pressure and high-temperature cathodic protection applications is presented. The invention protects flange faces from media induced corrosion and mitigates flange rotation induced fatigue and failures. The invention comprises of a retainer, a seal, and a seal pre-load structural ring. The seal pre-load structural ring is inserted into the seal, and seal outer diameter surface is joined to the retainer inner diameter surface. A second embodiment comprises of a composite gasket blank, comprising of a retainer and a seal, and a seal pre-load structural ring. The seal outer diameter surface and the retainer inner diameter surface are joined by thermal fusion bonding. The invention may further comprise one or more gasket seating stress stabilizers and/or a centering ring. Tapered retainer upper and lower surfaces decrease flange rotation.
