Compositions especially suitable for forming fibers and films having good elasticity and relatively high modulus are disclosed. Surprisingly, compositions including a styrenic block copolymer having a relatively high melt flow rate, and a detackifier, and optionally, but preferably in some embodiments a polyolefin (co)polymer, and/or polystyrene polymer, and/or a softener have good draw down performance and are processable into fibers having low tack, relatively high modulus and tensile strength. The fibers produced from the composition can be processed easily and are useful to manufacture articles such as fabrics, both woven and non-woven, webs, threads, and yarns. In various embodiments, unique fiber structures are produced having low tack and desirable elasticity.

Fiber forming compositions, fibers and methods for production

An expandable hose assembly that is able to expand one or more of longitudinally along the length-wise axis of the hose between hose ends and radially, to an expanded state in response to application of at least a minimum fluid pressure to an inner tube of the hose. Once the fluid pressure falls below the minimum fluid pressure, the hose will contract. The hose includes a thermoplastic elastomer inner layer and a slip coating layer thereon having lubricating properties that increases the life of the hose assembly. The hose assembly can include an outer sheath or covering that covers the inner tube and slip coating layer.

Multi-layer expandable hose

Thermoplastic elastomer compositions having a desirable soft touch feel to skin, and in particular grip, especially during wet, soapy and humid conditions. In one embodiment, the composition is part of a composite system, wherein the composition is connected, for example molded, overmolded or co-extruded to a substrate, such as a thermoplastic, glass or metal. The compositions and composites are suitable for use wherever desirable feel and grip are needed, such as handles or grips of household or industrial items.

Thermoplastic elastomer with desirable grip especially during wet conditions

A tube assembly including a flexible tube joined to a connector with the tube having an insert liner located therein at least in an area of a distal end of the connector that provides improved retention force between the tube and connector. Methods for preparing the tube assembly are disclosed and include the use of adhesives or solvent for bonding the tube to the connector.

Tube assembly and method for making the assembly

An adhesive system including a cyanoacrylate adhesive composition having a polymerization retarder that slows the polymerization rate of the cyanoacrylate, increases the lubricity to achieve proper assembly and aids in achieving desirable bonding properties of the adhesive; and a phosphorous-based primer that assists in preparing the components to be bonded. Methods of connecting dissimilar materials, preferably those used in medical applications, utilizing the adhesive system and the resulting adhered assemblies are disclosed.

Adhesive system, method of assembly of distinct components therewith

An adhesive system including a synergistic combination of a light curable silicone-containing adhesive composition and an amine-containing primer composition that provides desirable bond strength between two articles preferably one of the articles including a polyolefin or polyolefin-based thermoplastic elastomer. Methods of connecting articles, preferably those utilized in fluid transfer applications, utilizing the adhesive system and the resulting adhered assemblies are disclosed.

Curable adhesive system, method of assembly of distinct components therewith

Compositions including a thermoplastic elastomer or thermoplastic vulcanizate derived from a styrenic block copolymer having a reactive or crosslinkable hard block including aromatic vinyl repeat units and also preferably a crosslinkable soft block, and a non-olefin thermoplastic polymer or copolymer and preferably a compatibilizer such as the reaction product of a non-olefin thermoplastic polymer and a functionalized polymer such as a maleic anhydride functionalized styrenic block copolymer that is compatible with the styrenic block copolymer having a reactive or crosslinkable hard block, and optionally a linking compound. The vulcanizates are prepared by crosslinking the styrenic block copolymer in the presence of the non-olefin thermoplastic polymer and a suitable crosslinking agent, and optionally the compatibilizer, preferably utilizing dynamic vulcanization. In a further embodiment, thermoplastic vulcanizate compositions are provided including the styrenic block copolymer, a polyolefin polymer or copolymer, a non-olefin thermoplastic polymer and the compatibilizer.

Elastomer and vulcanizate compositions having desirable high temperature properties

Flame retardant polymeric blend compositions including a synergistic combination of flame retardants, including a halogenated flame retardant and a nanoparticulate, such as an organically modified clay or a natural nanoclay. The compositions are thermoplastic elastomers, include a polyolefin and a styrenic block copolymer, and exhibit high char formation upon burning as well as desirable vertical burn characteristics. In a preferred embodiment, the flame retardants include at least a halogenated flame retardant and a metal oxide.
