摘要： A flexible fiber reinforced hose adapted for conveying fluids under pressure. The reinforced hose having a core tube having at least one reinforcement layer surrounding an outer core tube surface. Each reinforcement layer having one or more woven mats, unwoven mats, or bundle of fibers comprising a plurality of reinforcement fibers that has a binder-resin filling at least a portion of the voids of the reinforcement fibers. In some aspects, the binder-resin adheres to the reinforcement fibers and displaces the air voids at the interface between the reinforcement fibers and the binder-resin. The binder-resin has a relatively low viscosity less than at least about 20,000 centipoise at 176° C. and low molecular weight, which allows the reinforcement layer to maintain a low flex modulus while maintaining or increasing tensile modulus. The reinforced hose also has at least one polymer layer that bonds to the binder-resin of the reinforcement layer, preferably being cross-linkable or cross-linked to the polymer layer.

摘要： Heterophasic propylene copolymer compositions may include a polymer matrix of a random propylene copolymer and an elastomeric copolymer dispersed in the polymer matrix in an amount ranging from about 10 to 35 wt. %, relative to the weight of the composition. The random propylene copolymer may include one or more comonomers in an amount ranging from about 0.5 to 8.0 wt. % of the random propylene copolymer. The elastomeric copolymer may include propylene and one or more comonomers, where the one or more comonomers are present in an amount ranging from about 15 to 60 wt. % of the elastomeric copolymer. Films may be formed from heterophasic propylene copolymer compositions. Methods of preparing heterophasic propylene copolymer compositions may include performing a multistage polymerization.

摘要： The present invention relates to a film structure comprising an outer layer, a core and an inner layer (or sealant layer). The outer layer comprises a polyolefinic material having a Vicat softening temperature of 85° C. or greater, and a total crystallinity in the range of 25 to 45%. The core comprises a linear low density polyethylene having a density of 0.925 g/cm3 or less, and a melt index of 4.0 g/10 min or less. The inner layer comprises linear low density polyethylene having a density of from 0.865 to 0.926 g/cm3 and a melt index of less than 4.0 g/10 minutes. The films of the present invention have less than 25% of polyethylenes having a density of 0.930 g/cm3 or greater. Further, the films of the present invention can be characterized by the substantial absence of polyamide, polyester, ethylene vinyl acetate, ionomers, polyvinyl chloride, and/or cyclic olefin polymers.

摘要： A thermoplastic polymer composition comprises a polyethylene polymer composition and a salt of bicyclo[2.2.1]heptane-2,3-dicarboxylic acid. The polyethylene polymer composition can have a Melt Relaxation Index of 2 or greater. A method for molding a thermoplastic polymer composition comprises the steps of (a) providing an apparatus comprising a die with an annular orifice, a means for blowing pressurized fluid into a tube exiting the die orifice, and a means for drawing and collecting the tube; (b) providing the thermoplastic polymer composition described above; (c) heating the thermoplastic polymer composition to melt the thermoplastic polymer composition; (d) extruding the molten thermoplastic polymer composition through the die to form a tube; (e) blowing a pressurized fluid into the tube to inflate the tube while simultaneously drawing it; (f) allowing the film to cool; and (g) collecting the film.

摘要： A catheter shaft is produced by forming a first polymeric layer onto a flexible inner core while maintaining the inner core in a solid state, and solidifying the first polymeric layer, wherein the solidified first polymeric layer fails to bond with the inner core and is slidable thereon upon flexion of the shaft. A second polymeric layer may be formed over the first polymeric layer, and is slidable thereon when the shaft bends.

摘要： The present invention relates to an external cooling system for a molten film tube produced by a blown film tubular extrusion process. Embodiments of the present disclosure provide a unidirectional cooling element having a unidirectional cooling interface containing a cooling gas deflector spaced adjacent to the molten film tube. The unidirectional cooling element operably expels cooling gas in a path with the flow of the molten film tube toward an exit gap formed between the unidirectional cooling interface and the molten film tube. The minimum gap between the unidirectional cooling interface and the molten film tube occurs at the exit gap, and advantageously, the unidirectional cooling interface is provided with one or more compound angles to maximize stability and cooling efficiency.
