A layer for directing a hydraulic fluid includes a first fluoropolymer, a first crosslinker, and an anti-static additive. The anti-static additive includes a portion of discrete carbon nanotubes and a dispersing binder. The dispersing binder is the same as or different than the first fluoropolymer. The first fluoropolymer is present in an amount greater than 30 parts by weight, based on 100 parts by weight of the layer. The layer may be included in a layered tube. In addition to the layer, the layered tube also includes an outer layer. The outer layer includes a second fluoropolymer, which is the same as or different than the first fluoropolymer and the dispersing binder. The second fluoropolymer polymer is present in an amount greater than 30 parts by weight based on 100 parts by weight of the outer layer.

Layered tube and layer for use in same

A layered tube for a hose assembly includes an inner layer that defines a chamber for directing a hydraulic fluid. The inner layer comprises a first fluoropolymer in an amount of from about 80 to about 99 parts by weight based on 100 parts by weight of the inner layer. The inner layer also comprises an anti-static additive in an amount of from about 1 to about 20 parts by weight based on 100 parts by weight of the inner layer. The layered tube also includes an outer layer surrounding the inner layer. The outer layer comprises a second fluoropolymer in an amount greater than 50 parts by weight based on 100 parts by weight of the outer layer. The second fluoropolymer may be the same as, or different than, the first fluoropolymer.

Layered tube for a hose assembly

A layer for directing a hydraulic fluid includes a first fluoropolymer, a first crosslinker, and an anti-static additive. The first fluoropolymer is present in an amount greater than 60 parts by weight, the first crosslinker is present in an amount of from about 1 to about 10 parts by weight, and the anti-static additive is present in an amount of from about 0.4 to about 4 parts by weight, each based on 100 parts by weight of the layer. The layer may be included in a layered tube. In addition to the layer, the layered tube also includes an outer layer. The outer layer includes a second fluoropolymer, which is the same as or different than the first fluoropolymer. The second fluoropolymer is present in an amount greater than 60 parts by weight based on 100 parts by weight of the outer layer.

A high pressure hose that is resistant to microvoid formation includes an inner tube comprising a blend of crosslinked fluoroplastic material and fluoroelastomeric material, a first reinforcement layer constructed of para-aramid synthetic fibers, and an adhesive layer, and an outer cover.

High pressure hose with polymeric tube

A method includes premixing an anti-static additive and a first crosslinker to form an anti-static intermediate mixture where the anti-static additive is dispersed in the first crosslinker. The method also includes compounding the anti-static intermediate mixture and at least a portion of the first fluoropolymer to form a first compounded mixture. The method further includes extruding the first compounded mixture to form a layer.
