    Abstract: A polychloroprene article comprises a polymer which is more readily chlorinatable that polychloroprene. A method of making the article comprises forming the article from an aqueous dispersion or solution of polychloroprene, characterized in that one or more polymers which are more readily chlorinatable than polychloroprene are included in said dispersion or solution. Preferably, the article is a polychloroprene glove containing carboxylated nitrile rubber, carboxylated styrene butadiene or polyisoprene.

  • Publication number: 20120124714
    Abstract: Multilayer elastomeric articles and methods of making the same are disclosed in which the outside or outer distal surface of the article is a different color or otherwise visually distinct in appearance from the inside or wearer contacting surface of the article so that the user of the article can readily identify the article as a multilayer elastomeric article. In one aspect, elastomer emulsions, solvent solutions, or plastisols used to form each layer may be modified with the addition of base color and/or colorant components in order to form a colored or patterned layer. In another aspect, one or both of the surfaces of the elastomeric articles (or layers of the articles) may be coated with such a colorant component to sufficiently visually distinguish the layers from each other.

  • Publication number: 20120121838
    Abstract: This invention relates to an elastomeric article with improved lubricity and donnablity and reduced stickiness/tackiness. According to the methods of the invention, the internal surface of the elastomeric article is coated with a polyisoprene coating. The coating of the invention is formed from synthetic polyisoprene rubber that may or may not contain minor amounts of other components. The coating is preferably directly bonded to the underlying elastomeric article.

    Abstract: Elastomeric film-like products such as natural latex gloves are coated with novel lubricity compositions and compositions which protect the skin of the wearer from certain undesirable medical conditions. In powder-coated gloves, the coating composition comprises rice starch, and optionally USP-grade colloidal oatmeal in pharmaceutically accepted concentration. In powder-free gloves, the coating composition comprises colloidal oatmeal enhanced water or beta glucan solution, optionally in combination with one or more other starch components. Colloidal oatmeal enhanced water, and methods of making the colloidal oatmeal enhanced water are also disclosed. In addition, beta glucan solution, and methods of making the beta glucan solution are also disclosed. A liquid referred to herein as Polycoat may also be made by mixing colloidal oatmeal enhanced water with beta glucan solution, and the resulting liquid may be applied to elastomeric articles such as gloves.

  • Publication number: 20120084901
    Abstract: The invention relates to method for producing a crosslinked elastomer by radiating a polymer dispersion of at least one crosslinkable polymer with electromagnetic radiation in the ultraviolet (UV light) and/or visible spectral range, wherein the crosslinking is performed in at least two stages as pre-crosslinking and post-crosslinking and at least one photoinitiator is added to the polymer dispersion to trigger the crosslinking reaction prior to the pre-crosslinking. At least one photoinitiator is added once again to the pre-crosslinked polymer dispersion prior to and/or during the post-crosslinking, and the post-crosslinking is also performed with electromagnetic radiation in the ultraviolet (UV light) and/or visible spectral range.

  • Patent number: 8117672
    Abstract: An improved process and material for making elastomeric nitrile rubber articles is disclosed. In particular, the process and material formulation can produce nitrile rubber based articles, which exhibit force-strain characteristics that are comparable to those of natural rubber latex articles, while maintaining the tensile strength properties of nitrile rubber. The process includes an accelerator composition at the pre-cure stage having a dithiocarbamate, a thiazole, and a guanidine compound. The invention also includes an elastomeric nitrile rubber product made by the process, such as examination, surgical, or work gloves.

  • Patent number: 8088461
    Abstract: The present invention aims to provide anti-slip gloves which exhibit excellent anti-slipping effects under slippery conditions such as wet conditions caused by moisture, detergents or oils, provide an excellent durability in repeated use, keep down production costs, and can be used in various applications. The glove of the invention has an anti-slip layer comprising pulverized fragments of a foamed melamine resin, or a mixture of pulverized fragments of a foamed melamine resin and NBR particles contained in a resin or rubber formed on the surface thereof. The pulverized fragments of the foamed melamine resin are particulate subfragments obtained by pulverizing the foamed melamine resin. The foamed melamine resin has a three-dimensional lattice structure, and the pulverized fragments of the foamed melamine resin obtained by pulverizing the foam have cut limbs extending three dimensionally, which are obtained by cutting the lattice parts.
