A thin organic solvent resistant glove is disclosed including: a first polymeric layer in a shape of a glove including at least one of a blend of a polyisobutylene material and a nitrile-butadiene material, or a nitrile-butadiene material; a second polymeric layer in a shape of a glove including at least one of a polyisobutylene material or a blend of a polyisobutylene material and a nitrile-butadiene material, disposed on the first polymeric layer, and a third polymeric layer in a shape of a glove including a nitrile-butadiene material or an acrylic polymer material disposed on the second polymeric layer.

Thin organic solvent resistant glove

A thin organic solvent resistant glove () is disclosed including: a first polymeric layer () in a shape of a glove including at least one of a blend of a polyisobutylene material and a nitrile-butadiene material, or a nitrile-butadiene material; a second polymeric layer () in a shape of a glove including at least one of a polyisobutylene material or a blend of a polyisobutylene material and a nitrile-butadiene material, disposed on the first polymeric layer, and a third polymeric layer () in a shape of a glove including a nitrile-butadiene material or an acrylic polymer material disposed on the second polymeric layer.

The present disclosure relates to synthetic polyisoprene elastomeric articles including: one or more cured blend compositions of pre-vulcanized synthetic polyisoprene particles and non-prevulcanized synthetic polyisoprene particles, wherein the pre-vulcanized synthetic polyisoprene particles and the non-prevulcanized synthetic polyisoprene particles are bonded by mono-sulfidic and/or di-sulfidic, and poly-sulfidic crosslinks, wherein the poly-sulfidic crosslinks are present in an amount of 60 to 79 percent of the total amount of crosslinks in the cured blend composition. Methods of making synthetic polyisoprene elastomeric articles such as gloves or condoms is also disclosed.

Compositions for synthetic polyisoprene latex articles

Polymeric gloves having stress-reducing ridges, and methods and formers for manufacturing polymeric gloves having stress-reducing ridges, are disclosed.

Stress reducing polymeric glove

A synthetic polyisoprene latex emulsion has pre-vulcanization composition and post vulcanization composition. The pre-vulcanization composition comprises soluble sulfur with high Sring structure that is catalytically broken by a zinc dithiocarbamate. Surfactants present in the pre-vulcanization composition wets synthetic polyisoprene particles and permeates small sized sulfur and accelerator molecules into the interior of these particles thereby pre-vulcanizing the particles. The degree of pre-vulcanization is verified by isopropanol index test. The latex emulsion has post-vulcanization composition with accelerators that crosslink inter-particle region during post vulcanization cure cycle. The dipped synthetic polyisoprene article is substantially uniformly cured both in the inter-particle and intra-particle regions and reliably exhibits high cross link density, uniform distribution of double bonds in TEM and zinc segregation at the boundaries or original particles by electron microprobe analysis. The films exhibit high tensile strength, tensile modulus, tear strength, burst pressure and burst volume.

Dip-formed synthetic polyisoprene latex articles with improved intraparticle and interparticle crosslinks

Polymer compositions that include polyisoprene and polychloroprene and methods for manufacturing protective articles from the polymer compositions are disclosed.

Provided herein are powder-free elastomeric articles exhibiting good antimicrobial and anti-blocking properties. Also provided herein are methods for the manufacture of such articles substantially free from antimicrobial interfering materials, as well as packaging means for maintaining antimicrobial efficacy.

Condoms having an elastomeric layer and coating containing an anhydrous warming lubricant and at least one or more ingredients dispersed therein, the coating being disposed on one or both surfaces are provided. The ingredients disposed on the elastomeric layer can be solid particles or encapsulated ingredients that are insoluble in the anhydrous warming lubricant and soluble in water. Methods of producing and using these condoms are also provided.

Condom with multifunctional coating

A latex glove article with a fibrous coating bonded to the skin-contacting surface. Long length soft moisture absorbing fibers are attached to latex layer of a glove with a thin layer of polymeric latex adhesive forming a fibrous lining. The long length fibers extend or project from the polymeric latex adhesive coating. The fibers penetrate the polymeric latex adhesive layer at one end or both end of the fiber to a depth of about 60% to about 100% of the adhesive thickness, leaving a substantial portion of the fiber available for soft contact with skin and sweat absorption. Due to the substantial thickness of the fibrous lining, which is between about 4 and about 100 times the thickness of the thin layer of polymeric latex adhesive, an air gap is created between skin and the impervious latex layer establishing continual evaporation of absorbed sweat and evaporative cooling.

Latex articles with geometrically defined surface structure providing enhanced grip characteristics in dry, wet or oily environment; and a method of making same comprising applying a polymeric coagulant coating to a smooth former surface, wherein the coating becomes tacky during drying, applying discrete coagulant particles of selected size, shape and distribution to the tacky coating to attach and protrude from the former surface with the polymeric coagulant coating, dipping the former into an aqueous latex emulsion, wherein the polymeric coagulant coating and the discrete coagulating particles destabilize the latex, thereby developing a latex layer, vulcanizing and stripping the latex article inside out, and dissolving the discrete coagulant particles in water or suitable solvents to reveal the geometrically designed texture with pre-selected size, shape and distribution of impressions providing improved dry, wet and oily surface grip by removal of a fluid boundary layer.
