Abstract: An electrical connector adapted for portable power distribution systems and other applications in various embodiments includes a versatile lug which may be selectively and repeatedly coupled to a stranded or other conductor and mounted and re-mounted on a bus bar or other mounting surface via a variety of attachment features on the lug. The lug offers numerous ways to attach it to a power bus and is designed for thousands of installations and re-installations each requiring the appropriate torque on the connector rather than a few such installations for which a known connector is designed and rated. The attachment features included in various embodiments of the lug connector allow for horizontal, vertical, side by side and edge clamping among other mounting configurations.

Abstract: A hot melt adhesive comprises an ethylene ?-olefin copolymer, an acid anhydride modified polyolefin and a hydrogenated tackifying resin. The hot melt adhesive has excellent viscoelastic properties and can be used in a variety of applications. In one application, attaching an elastic band to a flexible film, the adhesive has excellent viscosity and, in a finished absorbent article, a minimal creep characteristic. Also disclosed is a disposable article using the adhesive to adhere adjacent surfaces within the disposable article including an elastic band to a polyolefin backing film, for example, in a diaper, incontinent article or other such structure.

Abstract: Disclosed are hot melt adhesive compositions comprising a metathesized unsaturated polyol ester wax. Typically, the metathesized unsaturated polyol ester wax is derived from renewable starting materials such as vegetable oils or animal fats. The metathesized unsaturated polyol ester wax typically replaces a portion or all of a petroleum-derived wax or synthetic wax in various hot melt adhesive compositions. The hot melt adhesives may be conventional hot melt adhesives or hot melt pressure-sensitive adhesives.

Abstract: Described herein are fugitive hot melt adhesive compositions having a substantial weight percent of renewable plant-based content. The adhesive compositions impart high initial adhesive bond strength between an object and a substrate quickly after application in the molten state, wherein the adhesive bond strength is spontaneously substantially reduced to a very low or near zero level after a short time, for example between about 1 minute and 60 minutes after application. Methods of use and articles formed using the compositions are also described.

Abstract: A novel spray-on adhesive composition is made from a high melt index polymer and a rosin ester tackifier that interact to produce a composition that can form a low VOC, non-tacky, hot melt adhesive material that can be used in disposable article manufacture. The adhesive provides surprisingly high initial adhesion. Additionally, the adhesive is thermally stable at hot melt application conditions, low in cost, easily applied, and produces high quality disposable articles.
