摘要:
A hose including at least one rubber layer, an outer cover, and at least one barrier layer provided between the rubber layer and the outer cover, wherein the barrier layer is configured to prevent rubber from the rubber layer from reaching the outer cover during curing of the hose. In one embodiment, the rubber layer is the hose inner tube and the outer cover is braided wire. In another embodiment, the barrier layer includes at least one layer of polymeric film. In another embodiment, the hose can include at least one reinforcing layer provided between the rubber layer and the barrier layer. In another embodiment, the hose can include at least one intermediate layer provided between the rubber layer and the barrier layer, where the intermediate layer is formed from a porous material. In another embodiment, the hose can include at least one retaining layer provided between the barrier layer and the outer cover, where the retaining layer is formed from a polymeric material. Optionally, a composite barrier/retaining layer can replace the separate barrier and retaining layers.

摘要:
Compositions containing copolymers of epihalohydrins, an unsaturated epoxy comonomer, and optionally, ethylene oxide are readily cured to useful articles with peroxides when such compounds contain a polyacrylic acid ester of a polyol and Group IA, IIA, or IVA compound. Covulcanized compositions are prepared from mixtures of the epihalohydrin and epoxy copolymers with peroxy vulcanizable polymers.

Thermoplastic and thermoset materials containing an effective amount of an antistatic agent for improving antistatic properties thereof, the antistatic agent is selected from homopolymers and copolymers of an epihalohydrin.
摘要:
A nanocomposite composition includes a polymer and a barrier component sufficiently dispersed within the polymer so as to define a tortuous path within the polymer. The barrier component includes a nano-constituent including a plurality of layers and a macro-constituent including a plurality of particles. Each of the plurality of layers has a first average thickness and each of the plurality of particles has a second average thickness that is greater than the first average thickness. A nanocomposite system includes a substrate and a coating disposed on the substrate and formed from the nanocomposite composition.

A shaped hose assembly includes a length of hose having an external surface and a hose form including a non-continuous, generally curved wall that extends around the circumference of the external surface of the hose. The wall includes a first axially extending end and a second axially extending end. The hose form also includes at least one bend of predetermined radius. A method for shaping hose is also provided.
摘要:
A composition that is devoid of an unsaturation component, such as an unsaturated glycidyl ether, comprising a polymer of epihalohydrin, an acid acceptor, an unsaturated polyfunctional acrylate or methacrylate, and a curing agent consisting of an organic peroxide.
摘要:
Blends of epihalohydrin polymers and lower polyolefins containing an acid acceptor, an unsaturated polyfunctional acrylate or methacrylate, and a coagent that is cured with an organic peroxide provide low vicosity, improved hardness, easy processing, and improved physical properties on curing.
摘要:
An inflatable coupling component tube for a fluid-operated brake or clutch includes an elongated, generally tubular-shaped structure of predetermined length having two ends and a joint between the two ends that closes the tube to form a generally toroidal-shaped cavity. A coupling component for a fluid-operated brake or clutch that includes an inflatable tube, and a method of making an inflatable coupling component tube are also disclosed.
