Abstract
The present invention is directed to the production of elastomeric articles, such as elastomeric gloves, which can be easily stripped from forming molds, provide good tactile and gripping characteristics, and can be powder free with no halogenation or surface treatments. In general, the elastomeric articles of the invention include an ultra-thin outer layer formed of an acrylic-based polymer and a base polymer layer coagulated onto the surface of the outer layer which forms the primary matrix of the elastomeric article. The ultra-thin outer layer of the articles can be between about 0.25 microns and about 8.0 microns thick.
Claims28
An elastomeric article comprising:
- an ultra-thin outer layer comprising an acrylic-based polymer, said ultra-thin outer layer being between about 0.25 and about 8.0 microns thick;
- and
- a base polymer layer adjacent and attached to said ultra-thin outer layer, said base polymer comprising an elastomeric material which has been coagulated on said ultra-thin outer layer.
A glove comprising:
- an ultra-thin gripping layer comprising an acrylic-based polymer, said ultra-thin gripping layer being between about 0.25 and about 8.0 microns thick;
- and
- a base polymer layer, said base polymer layer comprising an elastomeric material selected from the group consisting of a natural latex rubber and a synthetic elastomer, said elastomeric material being coagulated onto said ultra-thin gripping layer through contact of said elastomeric material with a coagulant composition, said coagulant composition being applied to said ultra-thin gripping layer between said ultra-thin gripping layer and said base polymer layer.
A process for producing a glove comprising:
- forming an ultra-thin gripping layer comprising an acrylic-based polymer on a glove-shaped former, said ultra-thin gripping layer being between about 0.25 and about 8.0 microns thick;
- contacting said ultra-thin gripping layer with a coagulant composition;
- and
- forming a base polymer layer on said ultra-thin gripping layer, said base polymer layer comprising an elastomeric material, said elastomeric material coagulating on said ultra-thin gripping layer upon contact of said elastomeric material with said coagulant composition.
