Disclosed is a powder slush molding system that molds a slush skin by melting and adhering a powder resin material to an inner surface of a mold that is heated. The powder slush molding system includes a heating device, a rocking device, a cooling device, a demolding device, and a transfer device configured to transfer the mold between these devices. The cooling device includes a cooling bath and a table configured to turn upside down vertically above the cooling bath. The mold fixedly placed on an upper surface of the table faces the cooling bath side when the table is turned upside down. The table is configured to allow the mold to be placed also on a back surface of the table. The back surface faces upward when the table is turned upside down.

Disclosed is a silicone dipped glove, comprising a glove core and a dipping layer. The dipping layer is a silicone mixed compound layer, and the silicone mixed compound layer is composed of the following components at the following proportions by weight: 70-90% of silicone, 5-20% of a curing agent, 5-20% of a diluent, and 0-10% of a color paste. The silicone mixed compound layer of the present invention is composed of silicone, a curing agent and a diluent.

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%.

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 invention relates to the film products and methods of their preparation that demonstrate a non-self-aggregating uniform heterogeneity. Desirably, the films disintegrate in water and may be formed by a controlled drying process, or other process that maintains the required uniformity of the film. The films contain a polymer component, which includes polyethylene oxide optionally blended with hydrophilic cellulosic polymers. Desirably, the films also contain a pharmaceutical and/or cosmetic active agent with no more than a 10% variance of the active agent pharmaceutical and/or cosmetic active agent per unit area of the film.

An article comprises a laminate with a layer comprising a first latex composition containing a cross-linker component selected from sulfur, organic peroxide, vulcanizing activators, and vulcanizing accelerator; and a second layer comprising a second latex composition free of the cross-linker component. The laminate is formed by dipping a mold into the first latex composition then into the second latex composition forming a laminated film, then curing the laminated film by heating to a temperature between 90° C. to 140° C. Lastly, the laminated film is removed from the mold via inversion such that the second layer is inwards and the first layer is outwards.

There is provided a method and system for forming a composite material. The method includes: combining a first component element with a second component element to form a composite mixture; subjecting the composite mixture to a first force to in order to form ligaments and disperse the first component element and second component element in relation to each other, wherein the first force is a mechanical force, subjecting the ligaments to at least one second force in order to form attenuated ligaments and further disperse the first component element and second component element in relation to each other, wherein the at least one second force imparts both shear flow deformation and extensional flow deformation to the ligaments to form the attenuated ligaments; and collecting the attenuated ligaments. There is also provided a composite material prepared using the method described above.

An organic peroxide composition is provided which is liquid or near liquid at 25° C. or a low melting solid and which includes at least one ethylenically unsaturated organic peroxide (i.e., an organic peroxide containing at least one carbon-carbon double bond) and at least one saturated organic peroxide. The organic peroxide composition may further include at least one mono- and/or poly-unsaturated compound and at least one free-radical trap. The organic peroxide can be blended into a polymer such as a powdered or granular polyethylene resin. This peroxide-containing polymer can be used in rotational molding, wherein the polymer is added to a mold which is heated in an oven with rotation, thereby melting the polymer and coating the inside of the mold.

A latex of a styrene-based block copolymer includes a styrene-based block copolymer and water. The styrene-based block copolymer includes a toluene insoluble content of 30 to 95 wt %. The latex of the styrene-based block copolymer is superior in the processability and can provide a molded film such as a dip-molded product having the high tear strength, the high stress retention and the soft texture.
