Abstract:
A method of bonding a first article to a second article is provided. The method involves the use of a flowable, adhesive composition that contains non-aggregated, surface-modified silica nanoparticles dispersed in an epoxy resin.
Abstract:
An adhesive tape is provided which comprises a woven cloth, a polymer embedded into the cloth so as to cause the warp and weft fibers of the cloth to bond together at their overlapping points but not to completely encase the fibers, and a pressure sensitive adhesive coated onto at least a portion of the polymer, wherein the adhesive tape is hand tearable in the down-web and in the cross-web direction. A method of manufacturing such a tape is also provided.

Abstract:
A pressure-sensitive adhesive comprising a blend of at least two components, wherein the first component is at least one pressure-sensitive adhesive and second component is at least one thermoplastic material, wherein the components form a blended composition having more than one domain and, wherein one domain is substantially continuous (generally, the pressure-sensitive adhesive) and the other domain is substantially fibrillous to schistose (generally, the thermoplastic material). The second component can be (a) at least one thermoplastic elastomer, (b) at least one elastomer with a tackifying resin or (c) at least one elastomer.

Abstract:
The invention provides a pressure-sensitive adhesive composition for medical applications comprising a blend of at least two components comprised of about 5 to about 95% by weight of a first component comprised of at least one acrylic pressure-sensitive adhesive and about 5 to about 95% by weight of a second component comprised of either (a) at least one elastomer with a tackifying resin, or (b) at least one thermoplastic elastomer, wherein the resulting pressure-sensitive adhesive demonstrates a T.sub.0 of at least 1 N/dm and a T.sub.48 of less than 12 N/dm when adhered to skin. The pressure-sensitive adhesive composition is prepared either in the presence of a solvent or is alternatively prepared by melt blending. A method of preparing such an adhesive is also disclosed.

Abstract:
A cable includes a plurality of conductor sets. Each conductor set extending along a length of the cable and includes two or more insulated conductors, each insulated conductor including a central conductor surrounded by a dielectric material that includes polyolefin, a brominated flame retardant, and antimony trioxide. First and second conductive shielding films are disposed on opposite first and second sides of the conductor set, including cover portions and pinched portions arranged such that, in transverse cross section, the cover portions of the first and second shielding films in combination substantially surround the conductor set, and the pinched portions of the first and second shielding films in combination form pinched portions of the conductor set on each side of the conductor set. The cable includes an adhesive layer bonding the first shielding film to the second shielding film in the pinched portions of the conductor set.
