A glove for food handling has luminescent material kneaded throughout the entire area of the glove main body for food handling The luminescent material is configured to emit light in response to ultraviolet rays so that even if a broken piece of the glove for food handling mixes in food, the broken piece can be easily found by irradiating the food with the ultraviolet rays from an ultraviolet light source such as a black light. Further, on a palm surface of the glove for food handling, a plurality of fine first projections are formed, and a plurality of fine second projections are formed on each of the first projections.

One embodiment of the present invention relates to a chloroprene copolymer latex, a method for producing a chloroprene copolymer latex, a chloroprene copolymer latex composition, and a molded article or dipped product of a chloroprene copolymer rubber. The chloroprene copolymer latex is a latex of a chloroprene copolymer including monomer units derived from 2-chloro-1,3-butadiene (chloroprene) and monomer units derived from 2-methyl-1,3-butadiene, wherein the tetrahydrofuran insoluble content in the chloroprene copolymer is 20% by mass or less, and the proportion of the monomer units derived from 2-methyl-1,3-butadiene is 10 to 27 mol % in the chloroprene copolymer.

The present invention relates to an article of manufacture useful as an aftermarket product for fuel and electric vehicle (EV) and, more particularly, for a hand protective device and system and/or method to protect the user from contacting germs, hazardous contaminants, grime, electrocution, and/or other potentially harmful conditions, e.g. while fueling a petroleum and/or an electric powered vehicles. The device and system may be formed in the glove-shape with a fastener means (e.g. from hook and loop fabric) having a hook portion disposed on, for example, a gas cap of a car and/or on a cover of the charging connector and a loop portion 132 affixed or otherwise fastened to the palm portion of the glove. The device and system may further include an opening in a side opposite the palm portion to allow the hand to be slidably inserted easily using a tab located at a wrist portion.

A rubber formed article includes a laminate in which a rubber layer of nitrile rubber is laminated on a fiber base material. The nitrile rubber contains a copolymer having 52 to 78% by weight of conjugated diene monomer units, 20 to 40% by weight of ,-ethylenically unsaturated nitrile monomer units, and 2 to 10% by weight of ethylenically unsaturated monocarboxylic acid monomer units. Stress at 50% elongation of the laminate is 20 N or smaller. A ratio of an area where rubber is visible when the laminate is viewed from the back side to an area of the laminate is 15% or less. The thickness of the rubber layer is 0.30 mm or less.

The method comprises of placing the palm side of a glove mold facing up, and raising the fingers portion of glove mold up, in such a way that the glove mold is tilting up at 15-45 in relative to horizontal position. The first pouring process is carried out by pouring silica gel liquid on the fingers portion of glove mold. Then adjust the glove mold to horizontal position, and rotate the glove mold by using its length as axis. Continue pouring silica gel liquid on the glove mold surface to carry out second pouring process. Let the silica gel liquid to be coated on the whole glove mold surface forming a semi-finished glove. Upon completion, let the glove mold to go through a dripping procedure for dripping treatment. After the dripping treatment, carry out vulcanization and cooling to obtain the corresponding silica gel glove.

A sanitary automatic glove dispensing apparatus and method of use. The automatic sanitary glove dispensing apparatus, based on one or more received dispensing events, dispenses pairs of connected protective gloves stored on a roll of protective gloves and overlapped in a pre-determined pattern, by both cuff ends so both finger ends of the protective gloves are not contaminated during dispensing. After a pair of protective gloves are dispensed by both cuff ends, no additional protective gloves are exposed from the apparatus until another protective glove dispensing event is received, thereby protecting remaining protective gloves in the apparatus from contamination by noroviruses and bacteria from a surrounding environment and from other users of the apparatus.

A composition for rubber, including a chloroprene-based polymer latex (A), a metal oxide (B), an antioxidant (C), a surfactant (D) and a pH adjuster (E), and being free of a vulcanization accelerator, in which a tetrahydrofuran (THT) insoluble matter content in a chloroprene-based polymer in the (A) is from 50 mass % to 85 mass %, and in which contents of the (B), the (C), the (D), and the (E) with respect to 100 parts by mass of a solid content of the (A) are from 1 part by mass to 10 parts by mass, from 0.1 part by mass to 5 parts by mass, from 0.1 part by mass to 10 parts by mass, and from 0.01 part by mass to 5 parts by mass, respectively.

One method for creating barrier products (for example, condoms and gloves) includes: (a) dipping a former into a tank of elastic compound. The former has an indentation extending inwardly from an outer surface for creating a first protrusion on a first face of the barrier product. The method further includes: (b) removing the former from the tank of elastic compound, whereby some of the elastic compound removably adheres to the former and fills the indentation; (c) applying supplemental material to the elastic compound, whereby creating a second protrusion on a second face of the barrier product; and (d) fully drying the supplemental material. One barrier product includes an elastic wall having opposed faces, and first and second protrusions respectively extend from the opposed faces. The first and second protrusions are in cross-sectional alignment whereby rotational input forces on the first protrusion create rotational output forces on the second protrusion.

A process for removing protein contents from a rubber glove includes heating the rubber glove in water for 10-30 minutes; heating the rubber glove in a sodium carbonate solution for 50-70 minutes; and washing the rubber glove at least 2 times in washing water.

The present invention discloses a rubber composition. The rubber composition includes a rubber matrix and a crosslinking system. The rubber matrix includes, in parts by weight, the following components: a branched polyethylene with a content represented as A, in which 0<A100, an EPM with a content represented as B, in which 0B<100, and an EPDM with a content represented as C, in which 0C<100. Based on 100 parts by weight of said rubber matrix, the content of the crosslinking system is represented as D: 1D15 parts. The crosslinking system includes at least one of a crosslinking agent and an auxiliary crosslinking agent. The branched polyethylene has a degree of branching of not less than 50 branches/1000 carbon atoms, a weight average molecular weight of not less than 50,000, and a Mooney viscosity ML(1+4) at 125 C. of not less than 2.
