More Information
Summary:This application relates to synthetic elastomeric articles, such as gloves, comprising the cured product of a synthetic latex composition, the synthetic latex composition comprising a synthetic carboxylated polymer and a cross-linking composition, the cross-linking composition comprising an aqueous solution of a negatively charged multivalent metal complex ion having a pH of at least 9.0. Also described are compositions for forming the articles, and methods for making the articles, based on the use of the described cross-linking composition. The articles, compositions and methods contain an aqueous solution of a multimetal oxide of the multivalent metal, a hydroxide of the multivalent metal, or a salt of the multivalent metal, such as sodium aluminate, in an amount of less than 0.3 phr. The articles produced have a thickness of between 0.01-3 mm and an unaged tensile strength of at least 15 MPa.
