A method for cleaning medical equipment by scrubbing the equipment with an open-cell melamine-formaldehyde foam comprising an antibacterial active composition, and wherein the open-cell melamine-formaldehyde foam is prepared from a melamine-formaldehyde precondensate, wherein the molar ratio melamine to formaldehyde of the melamine-formaldehyde precondensate is smaller than 0.5.

The present invention relates to foam. In particular, the present invention relates to profiled foams and processes for profiling absorbent foam products. More particularly, the present invention relates to processes for producing a profiled absorbent polyurethane foam product, comprising the steps of foaming, curing, profiling and drying, wherein profiling occurs before drying; and absorbent aliphatic polyurethane foam products having at least one profiled surface.

Disclosed herein are matrices, compositions and methods of making matrices. The matrix comprises a biomolecule and the matrix is a dried, cross-linked foam. The matrix is not lyophilized. The method comprises foaming the composition, crosslinking the composition and drying the composition. Matrices disclosed herein are useful as wound dressings and treating wounds.

The present invention relates to a super absorbent polymer. The super absorbent polymer exhibits excellent initial absorption capacity, and thus can provide a sanitary material such as a diaper or a sanitary napkin which can quickly absorb body fluids and impart a dry and soft touch feeling.

The present invention relates to superabsorbent polymer and a method for preparing the same. The present invention can provide a superabsorbent polymer in which a hydrophobic material having an HLB of 0-6 and a surface cross-linking agent are mixed into a base resin prepared in the presence of water dispersible silica, thereby having improved rewetting characteristics and permeability through surface-modification of the base resin.

Embodiments herein are related to hydrophilic open cell foams with particulate fillers. In an embodiment, an article is provided that has an open cell foam structure including a hydrophilic polymer and about 0.1 wt. % to about 40.0 wt. % of a particulate filler dispersed within the hydrophilic polymer. The open cell foam structure can exhibit a rate of absorption of water greater than an otherwise identical foam lacking the particulate filler. Other embodiments are included herein.

A High Internal Phase Emulsion (HIPE) foam having cellulose nanoparticles.

This invention relates to a thermoplastic elastomer composition having a type A hardness (i.e., the momentary value) of 55 or less in accordance with JIS K6253, which comprises 35 to 65 parts by weight of an olefin-based thermoplastic elastomer (A) having a type A hardness (i.e., the momentary value) of 75 or less in accordance with JIS K6253 and 65 to 35 parts by weight of a styrene-based thermoplastic elastomer (B) having a type A hardness (i.e., the momentary value) of 60 or less in accordance with JIS K6253 (with the total amount of components (A) and (B) being 100 parts by weight) and a molded thermoplastic elastomer product obtained via molding of such composition.

A latex or natural rubber composition or formulation, latex or rubber products made using the same, and methods of preparing a vulcanized rubber and latex or natural rubber products are disclosed. The composition/formulation includes latex or natural rubber, 0.1-5 phr of a vulcanization activator, and 0.5-10 phr of one or more accelerators and/or additional activators. At least one accelerator and/or additional activator is a nanocomposite zinc oxide. The method includes. mixing a source of the latex or rubber with a vulcanization activator and one or more nanocomposite zinc oxides in a tank or vessel to form a latex or rubber formulation, dipping or at least partially immersing one or more molds or formers in the latex or rubber formulation to form a latex or rubber coating thereon, and curing the latex or rubber coating to vulcanize the latex or rubber coating. The vulcanized latex product is strong and has antimicrobial properties.

The present invention relates to a super absorbent polymer. The super absorbent polymer contains polymer particles formed of large pores in a certain amount or more, and thus can exhibit large surface area and excellent initial absorption capacity. Therefore, when the super absorbent polymer is used, it can provide a sanitary material such as a diaper or a sanitary napkin which can quickly absorb body fluids and impart a dry and soft touch feeling.
