摘要： A unique powder-free medical glove fabricated from a neoprene copolymer, and a method of making same is described. The gloves of the invention are easily donned without the use of powdered donning agents and retain their puncture resistance, tensile strength, stress at 500% and elongation to break after post-processing by chlorination and sterilization by irradiation. Additionally, the gloves of the invention exhibit minimal discoloration (as measured by the per cent change in yellowness index) and minimal stickiness to themselves and to glove packing materials after sterilization by irradiation.

摘要： An aqueous elastomer dispersion includes a dispersed phase and an aqueous phase. The dispersed phase includes an elastomer including curable aliphatic conjugated-diene elastomers, such as polyisoprene, and a minor amount of at least one additive. The aqueous phase includes water and other optional components in either a soluble state or a dispersion state. The aqueous elastomer dispersion may be prepared by dissolving an elastomer, such as rubber, and additives in a solvent mixture and then converting the resulting solution into an aqueous emulsion. The aqueous emulsion is concentrated and the solvent is stripped from it to yield a dilute latex. The dilute latex that is obtained is concentrated again. Articles made from the aqueous elastomer dispersion include medical gloves, condoms, probe covers, dental dams, finger cots, catheters and the like.

摘要： The invention disclosed herein relates to an improved process for making elastomeric polyisoprene articles. In particular, the process of the invention is a system which produces synthetic polyisoprene articles exhibiting tensile strength properties similar to that of solvent-based processes using natural rubber latex. The process comprises an accelerator composition at the pre-cure stage comprising a dithiocarbamate, a thiazole and a guanidine compound. In a preferred embodiment, the accelerator composition comprises zinc diethyldithiocarbamate (ZDEC), zinc 2-mercaptobenzothiazole (ZMBT) and diphenyl guanidine (DPG), in conjunction with a stabilizer, such as sodium caseinate. The invention also includes an elastomeric polyisoprene product made by the process, such as a surgeon's glove.

摘要： The invention described herein relates to a therapeutic, moisturizing coating composition for elastomeric articles which is applied directly onto the skin-contacting surface of the article as part of the manufacturing process. The coating composition is thermally stable and subsequently hydrates when contacted with a moisturized skin surface to convert into a liquid “lotion” form during wearing of the article. The coating composition provides therapeutic benefits to the wearer's skin as a result of wearing the article, such as improved skin moisturization, softness of feel, improved skin elasticity and firmness, and reduced redness and irritation. The invention is particularly useful in medical gloves, including examination and surgical gloves.

摘要： Powder-free natural rubber and synthetic elastomer gloves having an inner coating of a nitrile rubber with an intermediate layer of a rubber blend comprised of natural or synthetic rubber and nitrile rubber interposed between the nitrile coating and the base glove and their method of manufacture are described. The intermediate layer of the rubber blend interposed between the coating and the glove imparts a unique surface texture to the glove which aids donning and eliminates self-sticking of the inner glove surfaces, especially after the glove has been sterilized by radiation. Additionally the gloves of the invention exhibit good grippability, good donnability, superior tensile strength, elongation to break and stress at 500% elongation.
