Abstract: A water-based hydrogel polymer coating and a method of application to natural rubber or other elastomeric latex products are provided. The water-based hydrogel polymer is mixed with a blend of at least one elastomeric material to provide a hydrogel polymer blend composition. The water-based hydrogel polymer blend composition is applied in a single application to an elastomeric article, such as gloves, without additional solvents in the polymer blend composition and without a separate acid or chemical priming step. The water-based hydrogel coating herein provides increased lubricity to facilitate improved wet and dry donning of the elastomeric article.

Abstract: The invention relates to a protective device to be utilized on the handlebar of a vehicle equipped with control levers mounted on the handlebar adjacent to the handlebar grips. The device of the invention prevents control levers from imparting damage to the surroundings when the vehicle is transported. The device of the invention further protects the control levers and grips from damage by contact with nearby objects during transportation of the vehicle. The device of the invention further keeps a brake control lever in the fully pulled position, thus actuating the brake and preventing rotation of the braked wheel or wheels.

Abstract: Elastomeric articles, such as gloves, made from more than one layer, are provided. The gloves can include a first (grip side) layer in which a first colorant is compounded or integrated and a second (donning side) layer in which a second colorant is compounded or integrated. Alternatively, the gloves can include a translucent first layer and a second layer in which a colorant is compounded or integrated. Either arrangement can enable a breach of the first layer to be more easily detected, either due to the high level of contrast between the first layer and the second when a first colorant and a second colorant are utilized, or due to the translucence of the first layer as compared to the donning side layer, where the intensity of the second layer is increased upon a breach of the translucent first layer.

Abstract: A carboxylic acid-modified nitrile-based copolymer latex includes a carboxylic acid-modified nitrile-based copolymer including: 65.5 wt % to 82.5 wt % of a conjugated diene-based monomer-derived unit, 15 wt % to 30 wt % of an ethylenic unsaturated nitrile-based monomer-derived unit, and 2.5 wt % to 4.5 wt % of an ethylenic unsaturated acid monomer-derived unit, wherein the carboxylic acid-modified nitrile-based copolymer latex satisfies General Formula 1: 1.0 mm2/s≤CV0≤3.0 mm2/s [General Formula 1] wherein CV0 represents a capillary viscosity of the carboxylic acid-modified nitrile-based copolymer latex which is measured in a swollen state in a methyl ethyl ketone solvent.

Abstract: The present invention relates to a chloroprene copolymer latex composition, a molded article of chloroprene copolymer rubber, or a dip-molded product, and the chloroprene copolymer latex composition includes a chloroprene copolymer (A) and a vulcanization accelerator (B). The chloroprene copolymer (A) includes monomer units derived from chloroprene and from 2-methyl-1,3-butadiene. The chloroprene copolymer latex composition includes a carbamate-based vulcanization accelerator and a thiazole-based vulcanization accelerator as the vulcanization accelerator (B). The chloroprene copolymer latex composition enables production of a molded article having high flexibility and high tensile strength without use of a vulcanization accelerator that is feared to have skin sensitization.

Abstract: The technology relates to a method of producing a moulded polyurethane hydrogel, for example a condom. The method involves forming a solution of at least one polyurethane having a molecular weight of between about 40000 to about 500000 in a water:organic polar solvent comprising less than about 40% (v/v) water; applying a layer of the solution to a mould; drying the layer of the first solution to form a polyurethane film on the mould; and contacting the polyurethane film with a swelling agent under conditions such that the film forms a polyurethane hydrogel with a swelling agent content of between about 1% to about 95%.

Abstract: An improved glove has both anatomically correlating stress relief zones and/or reinforced zones to add support in areas opposite the stress relief zones to keep bunching or slipping of the glove from interfering with the bending of the user's joints. The glove may have corrugated relief zones over some or all of the joints and knuckles of the hand, wherein the relief zones are formed of peaks and valleys. A relief zone can also be provided over the webbing between the thumb and the palm. The vertical or longitudinal relief zones provide for improved glove quality while keeping manufacturing difficulty and costs at a minimum.
