A liquid latex emulsion is compressed to align the randomly arranged molecules to form rows of aligned molecules. A continuous flow of the liquid is created in the direction of the rows of aligned molecules. A first latex layer of rows of aligned latex molecules is created on a form by immersing the form into the continuous flow of compressed liquid at a first immersion angle. A second latex layer is created on the first latex layer, the second latex layer has rows of aligned latex molecules extending in a direction different the rows of aligned latex molecules of the first layer. The second latex layer is formed by immersing the form with the first latex layer into the flow of compressed liquid at an immersion angle different from the first immersion angle.

The present application relates to an elastomeric article, such as a glove, comprising: (i) an elastomeric film comprising one or more film layers, and including an external surface and an internal surface, (ii) an antimicrobial agent that is effective against both beneficial and harmful microorganisms on the external surface of the elastomeric film, and (iii) a skin-protective agent selected from a probiotic, a prebiotic, or a combination thereof on the internal surface of the elastomeric film; wherein the inner surface of the film is free of an antimicrobially-effective amount of an antimicrobial agent that is effective against both beneficial and harmful microorganisms. The elastomeric articles may further comprise a barrier film layer that provides separation between the antimicrobial agent and the skin-protective agent. Also described are methods for the manufacture of such articles.

Provided is a stretchable film that can prevent a delivery failure when delivered from a winding body. Also provided is a stretchable laminate including such stretchable film. Still also provided is an article including such stretchable laminate. The stretchable film of the present invention includes a laminated film of a plurality of elastomer layers, wherein the stretchable film includes an elastomer layer (A1), an elastomer layer (B), and an elastomer layer (A2) in the stated order, wherein the elastomer layer (A1) and the elastomer layer (A2) are provided as outer layers, and wherein each of the elastomer layer (A1) and the elastomer layer (A2) contains a fatty acid amide.

Provided is a method for manufacturing a laminated rubber hose that includes a first layer and a second layer laminated on an outer surface of the first layer, the first layer containing a thermosetting resin in an amount of 4.5 parts by mass or less relative to 100 parts by mass of a rubber component, the method including laminating the second layer on the outer surface of the first layer with the outer surface of the first layer maintained at a temperature range of 65 C. or more and 105 C. or less.

A roofing membrane comprising at least one layer of a cured rubber and expandable graphite dispersed within the cured rubber.

The invention relates to an article having a single-layered or multilayered main body having elastic properties, in particular an air spring bellows, a metal-rubber element or a vibration damper.

To improve the flame-retardant properties the main body of the article consists of or contains at least one layer D which is constructed from a rubber mixture which is free from halogen-containing flame retardants and contains at least one carbon black having a BET surface area according to DIN-ISO 9277 between 35 and 140 m.sup.2/g and an oil absorption number (OAN) according to ISO 4656 between 70 and 140 ml/100 g.

Crumb rubber obtained from recycled tires is subjected to an interlinked substitution process. The process utilizes a reactive component that interferes with sulfur bonds. The resulting treated rubber exhibits properties similar to those of the virgin composite rubber structure prior to being granulated, and is suitable for use in fabricating new tires, engineered rubber articles, and asphalt rubber for use in waterproofing and paving applications.

The present invention relates to a process for electroplating an adhesive composition onto at least one conductive element, in which the conductive element is placed in contact with the adhesive composition comprising: a phosphate salt and a resin based on: a compound A1, compound A1 being chosen from a compound A11 comprising at least two functions, one of these functions being a hydroxymethyl function and the other being an aldehyde function or a hydroxymethyl function, or a compound A12 comprising at least one aldehyde function, or a mixture of a compound A11 and of a compound A12; and a phenol A21. A potential difference is applied between the conductive element and the adhesive composition to coat the conductive element with an adhesive layer.

An adhesive includes a polymeric latex, a penetrant selected from the group consisting of: terpenes, polylimonene, limonene, carvone, a-pinene, citral, dipentene, 1,8-cineole, eucalyptol, citronellol, geraniol, citronellene, terpinen-4-ol, borneol, camphor, guayule resin, and combinations thereof; and a reinforcing filler. The adhesive has a solids content of 35-65% and a pH of 9 to 12. Articles of manufacture, such as tires and air springs incorporate the adhesive to join rubber interfaces. A method of making the adhesive is also is provided.
