A composition for laminates, comprising: (a) an epichlorohydrin polymer; (b) a compound having a vinyl group; (c) at least one compound selected from the group consisting of a 1,8-diazabicyclo(5.4.0)undecene-7 salt, a 1,5-diazabicyclo(4.3.0)-nonene-5 salt, 1,8-diazabicyclo(5.4.0)undecene-7 and 1,5-diazabicyclo(4.3.0)-nonene-5; and (d) a metal salt hydrate.

A flexible hose liner is provided having a cylindrical body extending along a longitudinal axis from a first end to a second end. First and second sleeves form the cylindrical body by separate continuous ribbons having a plurality of convolutions formed in a helical pattern along the cylindrical body from the first end to the second end. A ring is formed in each revolution about the longitudinal axis of the continuous ribbon of the first and second sleeves. A plurality of rings form the cylindrical body, each ring has a first convolution and an ending convolution such that a mechanical connection is formed between the ending convolution of a preceding ring and the first convolution of a succeeding ring. The mechanical connection of the between the rings of the first sleeve being different from the mechanical connection of the rings of the second sleeve.

A metal-shelled hose assembly includes a metal outer shell lined with a flexible, water-tight inner tubing integrated with a bendable strain-relief section that is configured to allow the metal-shelled hose to be pulled from a straight angle regardless of where it is attached. The bendable strain-relief section is provided at least at the faucet end of the hose, where it effectively changes the angle of the length of the metal hose relative to the faucet when the hose is pulled at an angle to the faucet.

The invention provides a cross-linked fluororesin having excellent abrasion resistance against metal. The cross-linked fluororesin is obtainable by cross-linking a fluororesin. The fluororesin contains a tetrafluoroethylene unit and a vinylidene fluoride unit, and the tetrafluoroethylene unit represents 50.0 mol % or more of all the monomer units constituting the fluororesin.

Apparatus for providing a thermal insulation layer in a flexible pipe, including one or more encapsulated regions of aerogel material disposed in a layer of flexible pipe body is disclosed. In addition, flexible pipe body including such apparatus, and a method of manufacturing flexible pipe body is disclosed.

An elastic tubular body includes a grommet fitted to an opening edge of a mounting hole of a support body, a flared portion formed in a flare shape and deformable so as to invert an inner face and an outer face and having a large diameter edge coupled to the grommet; and a bellows-like tube of a bellows-like tubular shape having a smaller diameter than an inner diameter of a small diameter edge of the flared portion, a first end of the bellows-like tube connected with the small diameter edge of the flared portion. The flared portion is configured to be in a state projecting from the grommet or in a state where the outer face is reversed to enter inside the inner face and store the flared portion in a storage space of the grommet. The bellows-like tube is stored inside the flared portion stored in the storage space.

A plastic corrugated tube having corrugations distributed over its length and a longitudinal slit running along a lateral longitudinal line is provided. The corrugated tube can be converted into an open position by opening the longitudinal slit and into a closed position in which edge regions of the corrugated tube overlap, wherein the corrugated tube is elastically prestressed toward its closed position. The corrugations on the edge region of the corrugated tube, which in the closed position lies radially below the other edge region of the corrugated tube, are offset radially inwards within a predefined circumferential region with respect to the corrugations outside this circumferential region and are designed such that, in the closed position, they are in engagement with the radial underside of the corrugations of the other edge region, which corrugations engage over them such that they are mutually displaceable in the circumferential direction.

A fluid delivery system includes one or more smart hoses. A smart hose of the one or more smart hoses includes a fluid conduit configured to deliver a fluid. The smart hose further includes a first electrically conductive element configured to deliver electricity through a length of the smart hose.
