The present invention relates to a latex composition for dip-molding and a molded article produced therefrom. More specifically, the composition not only has gentle syneresis, and excellent tensile strength, elongation and modulus, and excellent durability against perspiration, but also is capable of preparing the dip-molded articles having excellent wearing sensation.

A latex formulation for making an elastomeric product, more particularly an elastomeric glove. The formulation comprises a mixture of at least one base polymer, a cross-linker; and a pH adjuster, where the pH adjuster provides a pH range of 9.5 to 10.5 to the latex composition. Still further, the present invention discloses a method for preparing a latex formulation for making elastomeric products, such as an elastomeric glove, without using accelerators, zinc oxide or sulphur.

The invention relates to a method for the manufacture of a prophylactic article, especially of a glove, from a (carboxylated) diene rubber, according to which a layer of a (carboxylated) diene latex is applied on a former and the (carboxylated) diene latex is cross-linked with a cross-linking agent, which is immobilized on inorganic and/or organic particles with formation of modified particles, and the modified particles are added to the (carboxylated) diene latex.

A method for producing a glove includes a step of forming a dip-molded layer by dip-molding a latex composition containing a latex of a carboxyl group-containing conjugated diene rubber (A) that does not have an isoprene-derived monomer unit, and a metal compound (B) including a divalent or higher metal, and a step of irradiating the dip-molded layer with radiation.

The present invention relates to a latex composition for dip-molding comprising a mixture of latex pigment and carboxylic acid-modified nitrile based copolymer latex which are two types of latex having Tg different to each other, and a dip-molded article produced therefrom.

The dip-molded article according to the present invention does not use sulfur and a vulcanization accelerator and thus has a low risk of allergies and can have excellent elasticity, while maintaining the physical properties such as tensile strength and modulus in the trade-off relationship opposite to each other at the levels equal to or higher than those of the prior art, so that the dip-molded article can be easily applied to industries in need thereof, such as industry of rubber gloves, etc.

Described are systems, devices, and methods for stripping a formed thin film elastomeric article such as a latex or synthetic polymer medical or surgical glove from a mold, inverting the article, and transferring and securing the inverted article to a mandrel for further on-line processing, integrating dip forming and off-line surface treatment processes into a single, continuous on-line process. The system can include a stripping apparatus including an actuation device for peeling the article from the mold and inverting the article, and a donning device to receive the inverted article. The system may position the article about a mandrel of the donning device. The mandrel may expand or separate to engage the interior of the inverted article to securely hold the article on the mandrel. The donning device may be coupled to a continuous loop conveyor chain to carry the donning device and the mounted article through on-line secondary processing.

The problem to be solved is to provide a technique which allows hand-mask users to effectively make use of the waiting time with the hand masks on their hands, and perform skin care or a similar treatment on their hands without feeling stressed. This problem is solved by a hand mask including: a glove part made of a liquid-retentive material and having a shape that wraps around the entirety of five fingers inclusive of the fingertips as well as the back and palm of a hand; and a cutoff line formed in a finger-covering portion in the glove part along a circumferential direction of the finger-covering portion, for allowing a fingertip-wrapping portion to be cut off.

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

The present invention is to an improved glove having 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.
