  • Patent number: 11639433
    Abstract: Methods for fabricating rubber-based elastomeric materials are disclosed. In an embodiment, a method for fabricating a rubber-based elastomeric glove includes milling diene rubber to form first and second milled diene rubber portions; forming a first mixture by mixing a silica reinforcing component and a first antiozonant wax with the first milled diene rubber portion; forming a second mixture by mixing a second antiozonant wax with the second milled diene rubber portion; mixing the first mixture, the second mixture, and a solvent to form a viscous solution; and dipping a glove mold into the viscous solution for a selected number of dips, and evaporating the solvent from the glove mold between dips to form the rubber-based elastomeric glove, wherein the elastomeric glove has a thickness of at least about 30 mils, and wherein the elastomeric glove exhibits a flexural modulus of less than about 0.06 MPa.

  • Patent number: 7005478
    Abstract: The present invention is directed to methods of making natural or synthetic latex articles without the use of accelerators, thiurams or carbamates. The method includes making an elastomeric material by mixing a base polymer containing carboxylate groups with a carboxylic acid or derivative thereof, a divalent or trivalent metal, an amine or amino compound, and a neutralizing agent. The elastomeric material is formed into a latex article. The present invention is also directed to a latex article made according to this method. The latex article does not contain any accelerators, thiurams or carbamates.
