The latex impregnation is disposed on at least one of the first and second surfaces and penetrates the non-woven fibrous material of the binderless core an impregnation distance.

Systems and methods for creating a grip surface (104) of a protectant glove (100). The method may comprise dipping a glove mold into a coagulant material (206); dipping the glove mold into a nitrile coating formulation to form an outer surface of the glove (208), wherein a biodegradable material is distributed throughout the nitrile coating formulation; vulcanizing at least the outer surface of the glove to form a protectant outer surface (212); washing at least the outer surface of the glove with an enzyme solution; decomposing, by the enzyme solution, the biodegradable material that is distributed throughout the outer surface of the glove, thereby forming a grip surface of the glove comprising an open-cell structure within the outer surface (216); and drying the glove to form a final glove comprising the grip surface (218).

Provided among other things is a method of forming a composite glove with a grip texture, comprising: (a) providing a coagulant-coated support layer that is a fabric layer or a polymeric layer; (b) dip applying to the support layer a foamed polymer dispersion comprising about 0.5% to about 2.0% by weight hygroscopic agent; (c) allowing a portion of the applied foamed polymer dispersion to coagulate based the coagulant diffusing from the support layer to form a partially coagulated foam layer; (d) washing the partially coagulated foam layer to remove uncoagulated polymer to form a coagulated foam layer; and (e) vulcanizing the coagulated foam layer to form a vulcanized open foam layer laminated to the support.

The present disclosure relates to an ultrasound phantom for a focused ultrasound wave. More specifically, the present invention provides an ultrasound phantom which mimics a body so as to correspond to a speed of sound in the body, in which agarose, sucrose, polydiacetylene vesicle, and distilled water are mixed, and a specific part onto which an ultrasound wave is irradiated by a focused ultrasound transducer is gradually discolored in accordance with a temperature.

A dip-molded article includes an external molded layer and internal molded layer. The external molded layer includes a content of an ethylenically unsaturated nitrile-based monomer-derived repeating unit is 35 wt % to 60 wt %, and the internal molded layer in which a content of an ethylenically unsaturated nitrile-based monomer-derived repeating unit is 10 wt % to 28 wt %.

A method of preparing a carboxylic acid-modified nitrile-based copolymer latex is provided. The method of preparing a carboxylic acid-modified nitrile-based copolymer later includes emulsion-polymerizing a monomer mixture including a conjugated diene-based monomer, an ethylenically unsaturated nitrile-based monomer, and an ethylenically unsaturated acid monomer in the presence of a cross-linking agent including glyoxal.

An animal toy is provided constructed from a latex or natural rubber material and formed into a ball. The ball is formed of an aggregate of particulate material that are bound together to form a substantially non-hollow construction. Pieces of latex are joined together to form balls, and the balls may be pressed together and constructed by hand or, alternatively, pressed into molds. By constructing the balls by hand, no two balls, even balls of similar size, are identical. Each ball has irregular outer surface that forms a variety of resilient protuberances that provide beneficial oral hygiene effects when chewed or rubbed against the teeth.
