Abstract: Disclosed is a catheter with an antimicrobial coating that reduces the development of device-associated urinary tract, respiratory and bloodstream infections and methods for making the same. The disclosed method comprises the layered application of one or more organic solutions to a coatable elastomeric product which results in a device that allows for a controlled time release of iodine therefrom. Application of one or more antitoxic agents in multiple layers and locations on the desired elastomeric product helps to tailor delivery and potency of the antimicrobial coating.

Abstract: The invention relates to process for creating catheters that are coated with these layers of elastomeric polymeric coating with an antitoxic agent, antimicrobial resin, affixed to the surface of said polymeric coating. The method of coating an elastomeric material on the exterior and/or the interior includes: (a) providing a base elastomer comprised of an elastomeric polymer; (b) dipping the elastomer in a second organic solution containing a polymer to form a secondary coating over the barrier coating; (d) coating the elastomer with suspension containing polyiodinated resin particulate in an organic solvent to anchor the particulates to the secondary coating; and (e) drying the elastomer.

Abstract: A composition for forming an elastomeric article is disclosed. The composition includes an elastomeric material and a film leveler, where the film leveler is present in an amount of from about 0.05% to about 5.0% by mass of the composition.

Abstract: An elastomeric article includes a substrate body formed from an elastomeric material. The substrate body has a first surface, and a donning layer overlying at least a portion of the first surface. The donning layer is formed from a modified vinyl acetate polymer.

Abstract: The present invention is directed to breathable elastomeric gloves. The gloves of the present invention may allow the transmission of water vapor while still providing an effective barrier to virus, bacteria, contaminants, bodily fluids, and the like. In general, a breathability additive may be incorporated into the polymer matrix of one or more layers of the glove to improve the breathability of the layer. For example, polyethylene oxide may be incorporated into a layer as a breathability additive.

Abstract: An elastomeric article includes a substrate body including a first surface. The substrate body is formed from an elastomeric material. A donning layer overlies at least a portion of the first surface. The donning layer is formed from a styrenic block copolymer.

Abstract: Disclosed is an elastomeric article, such as an elastomeric glove, for example, and a method for making the disclosed elastomeric article. The elastomeric article includes a fluorocarbon graft on the donning surface of the article. In addition, a hydrophilic lubricant including a modified siloxane displaying polar functionality may be applied to the surface of the article. In one embodiment, the modified siloxane may be an amino modified siloxane. The silicone lubricant and the fluorocarbon graft display a synergy, providing an article with improved dry slip characteristics and improved wet slip characteristics. In addition, a fatty alcohol may be applied to the surface of the article, further improving the damp slip characteristics of the article.

Abstract: An elastomeric article such as a glove includes a substrate body made of an styrene-ethylene-butylene-styrene block copolymer, and a donning layer overlying at least one side of the substrate body. The donning layer is formed of 1,2 polybutadiene, preferably syndiotactic 1,2 polybutadiene, or a chlorinated mid block unsaturated block copolymer. Optionally, a surfactant layer is present over the donning layer to further improve the donning characteristics. The surfactant layer is preferably an alkyl dimethylbenzyl quaternary, an alkyl trimethyl quaternary, a dialkyl dimethyl quaternary, sodium lauryl sulfate, or pyridinium chloride.

Abstract: An elastomeric article (e.g., glove, condom, etc.) that includes a chemical protection layer that will not substantially dissolve when applied with certain chemicals or solvents, such as methyl methyacrylate, is provided. The chemical protection layer contains at least one crosslinked, modified silicone elastomer. For example, in one embodiment, the modified silicone chemical protection layer covers the outer surface of a styrene-ethylene-butylene-styrene (S-EB-S) block copolymer substrate body to impart relative chemical resistance to the resulting elastomeric article.

Abstract: An elastomeric article such as a glove includes a substrate body made of an styrene-ethylene-butylene-styrene block copolymer, and a donning layer overlying at least one side of the substrate body. The donning layer is formed of a chlorinated styrene-isoprene, preferably having a polystyrene block content of from about 10 to about 20 percent by weight of the total copolymer weight and an end block polystyrene molecular weight of at least about 5,000. Optionally, a surfactant-containing layer may be present over the donning layer to further improve the donning characteristics. The article is preferably prepared by dip forming the article from an styrene-ethylene-butylene-styrene block copolymer, coating the article with a solution of the styrene-isoprene block copolymer, removing the solvent, and chlorinating the styrene-isoprene block copolymer.

Abstract: Turbulent-flow emitter channel sections are vacuum-formed in an extruded flat plastic strip. The strip is then applied to a hose substrate, and inlet and outlet openings are formed at opposite ends of the channel sections. The strip may be hot-melt bonded to the substrate during a co-extrusion process, or it may be applied to the hose substrate in a separate operation. Flow rates are easily controlled without changing the structure of the strip by varying the number of channel sections in which outlet openings are formed.

Abstract: An emitter includes a body member having a head portion. The head portion has an outer peripheral surface that defines an elongated channel and the channel extends along a tortuous path from an inlet end of the channel to an outlet end of the channel. A cover of heat shrinkable material is shrunk over the outer peripheral surface of the head portion covers the channel to form a turbulent flow passage. The head portion may include generally opposed, first and second transverse surfaces between which the outer peripheral surface extends, the cover extending partially over the transverse surfaces to form flanges that engage the transverse surfaces. The heat shrinkable material may be shrinkable both axially and circumferentially for this purpose. One embodiment includes an emitter outlet in the form of an annular basin that is fed with a non-radially disposed slot to produce a self-cleaning vortex action.
