Elastomeric chemical barrier articles

An elastomeric glove providing a chemical barrier, the glove having a layered structure comprising:

• (a) an aqueous latex-based elastomeric polymeric barrier layer formed by dipping a former into a colloidally stable blend comprising greater than about 50% by weight of a rubber lattice blended in an aqueous elastomeric latex, the rubber lattice comprising natural rubber, chloroprene rubber, butyl rubber, acrylonitrile butadiene rubber, styrene-butadiene rubber, polyurethane, or a combination thereof;
• (b) a non-reactive tie adhesive resin layer comprising oxo (—(C═O)—) groups, disposed by dipping on the aqueous latex-based elastomeric polymeric barrier layer each comprising a carbon atom doubled bonded to an oxygen atom;
• and
• (c) a polyamide layer disposed on the non-reactive tie adhesive resin layer by dipping, comprising polyamide polymer;
• wherein one or more of the layers are dried and cured after said dipping;
• wherein the layered structure has a first side nearest the aqueous latex-based elastomeric polymeric barrier layer and a second side;
• wherein, for permeation time measured pursuant to EN 16523-1:2015 and compared to a comparative layer of material of the aqueous latex-based elastomeric polymeric barrier layer of a thickness of the layered structure, the layered structure is effective to provide an acetone chemical permeation time superior to that for the comparative layer, whether the acetone is applied on the first side or the second side, and an ethyl acetate and a methanol permeation time superior to those for the comparative layer when applied to the first side, wherein for one such measurement the permeation time is about five-times or more superior to the comparative layer, and
• wherein the aqueous latex-based elastomeric polymeric barrier layer is less than 50% by weight polyolefin, and
• wherein the aqueous latex-based elastomeric polymeric barrier layer provides greater than about 50% of a thickness of the glove.
