A pipe includes an outer surface with a polyolefin-based protective coating covering a substantial portion thereof In addition, an end wrap material is disposed on the protective coating proximate to an end of the pipe, where the end wrap material is bondable to a polymer-containing protective material, such as a heat shrink sleeve or cover. The end wrap material can bond a heat shrink cover or sleeve in place over a girth-weld, thus substantially reducing the likelihood of the disbandment or movement of the sleeve from the welded pipe ends over time.

A pipe system comprises first and second pipes having first and second ends welded together forming a girth-weld and a heat recoverable polymer material comprising a plurality of holes extending therethrough covering the girth-weld. The heat recoverable polymer material can include a surface having an adhesive coated thereon disposed on the girth-weld. Air trapped underneath the recoverable polymer material can be released through the plurality of holes during shrinking of the heat recoverable polymer material. Also, a portion of the adhesive can flow through the holes during a shrinking of the heat recoverable polymer material.

A pipe system includes first and second pipes having first and second ends welded together forming a girth-weld and a corrosion coating covering the girth-weld. In addition, a flexible sheet is provided to cover the girth-weld. The flexible sheet comprises a first structured layer that mechanically couples to the corrosion coating, where the corrosion coating permeates a substantial portion of the first structured layer. The flexible sheet also includes a second layer comprising a polymer layer adhered to the first layer, the second layer protecting the corrosion coating from mechanical or environmental damage. Alternatively, the protective cover comprises a polymer material and includes a port formed therethrough adapted to receive a delivery mechanism that delivers a corrosion coating to the girth-weld.

An earplug system that includes a foam earplug and a deformable sheath that individually surrounds at least the body of the foam earplug in a noncompressed condition. The deformable sheath allows the earplug to be compressed with a person's fingers in the sleeve before being placed within the user's ear. In this manner, the earplug can be inserted into the ear canal without being soiled or otherwise contaminated from a wearer's unclean hands.

Light management film constructions contain a first optical film having a first major surface and a second major surface opposite the first major surface. The first major surface is a micro structured surface with asymmetrical structures. The asymmetrical structures form an ordered arrangement of a plurality of multi-sided refractive prisms, with the multi-sided refractive prisms having a cross section of 3 or greater sides. A second optical film contacts and is bonded to substantially all of the structures of the first major structured surface of the first optical film. The light management constructions can be incorporated into optical articles such as windows.

The present invention is directed to a novel polymodal asymmetric elastomeric block copolymer and a pressure sensitive adhesive and tape made therefrom. The novel block copolymer comprises from about 4 to about 40 percent by weight of a polymerized monovinyl aromatic compound and from about 96 to about 60 percent by weight of a conjugated diene. The block copolymer has the general formula Q. sub. n Y where Q represents an individual arm of the block copolymer and has the formula S-B; n represents the number of arms and is at least 3; and Y is the residue of a multifunctional coupling agent. Furthermore, S is a nonelastomeric polymer segment endblock of a polymerized monovinyl aromatic homopolymer, there being at least two different molecular weight endblocks in the block copolymer. The number average molecular weight of the higher molecular weight endblock (Mn). sub. H is in the range of from about 5,000 to about 50,000, and the number average molecular weight of the lower molecular weight endblock (Mn). sub.
