  • Patent number: 10500797
    Abstract: Provided for example is a method of forming texture comprising: (I) providing a polymeric layer with first and second sides, wherein the polymeric layer is made from a polymeric material that gels on contact with a gelling agent, and wherein the first side is gelled, with gelling extending into the polymeric layer but not to the second side; (II) contacting the second side of the polymeric layer with a foamy aqueous solution of surfactant (one or more), the aqueous foam being in the process of collapsing during the contacting, wherein the aqueous solution of surfactant is effective to gel the polymeric material; (III) applying a aqueous medium to the second surface with sufficient force or agitation so as to remove a portion of the polymeric material; and (IV) curing the remaining polymeric material without, following the contacting step, further contacting the polymer layer with a gelling component.

  • Publication number: 20150037529
    Abstract: Provided for example is a method of making an lined elastomeric article comprising: (I) applying to a base elastomer layer a foamed or unfoamed composite of flock fibers and aqueous elastomer, wherein (a) if the elastomer base layer polymer component is (i) not predominantly NR or (ii) not predominantly NR plus NBR, then the elastomer of the composite comprises NBR, wherein NBR and if present acrylic latex are (1) substantial in the composite or (2) predominate in the composite, and/or wherein (b) the elastomer of the composite comprises acrylic latex, NBR and, if the elastomeric base layer is not predominantly NBR, the major elastomer of the base layer.

  • Patent number: 7122593
    Abstract: A latex article is provided that contains chromium oxide particles dispersed throughout a cured latex layer. The chromium oxide particles render the latex article, or smaller pieces of the latex article, magnetically detectable. The chromium oxide may be present within the latex in combination with magnetically detectable ferrite. The article may include multiple cured latex layers having chromium oxide or magnetically detectable ferrite dispersed throughout the cured latex layers.

  • Patent number: 7048884
    Abstract: A process for producing an article in a flexible foamed polymer material, including treating a former with a coagulant; dipping the treated former in a latex foam mixture to form a layer of the mixture on the former that includes air cells; curing the layer to gel the foam mixture to a cross-linked open cell structure; and stripping the layer from the former; where the latex foam mixture includes a natural latex polymer as a primary polymer component, and a synthetic latex polymer as a secondary polymer component, which synthetic latex polymer is selected to enhance the evenness and/or fineness of said open cell structure.
