The present invention provides a structure that improves sound absorption coefficient. The present invention provides a structure comprising: a foam resin layer formed of a foam material having a foaming ratio of 1.1 to 8 times; and a sound absorbing layer formed of a foam material having a foaming ratio of 10 to 30 times, the sound absorbing layer laminated on the foam resin layer.

The present disclosure relates generally to polymer structures, for example, suitable for construction products. The present disclosure relates more particularly to a thermoplastic construction product including a coextruded layer structure having a base layer including a first thermoplastic material, an outer layer including a second thermoplastic material, and an infrared-reflective intermediate layer that is coextruded with the base layer and the outer layer and is disposed between the base layer and the outer layer. In some embodiments the intermediate layer has a thickness of at least 30 micrometers. In some embodiments the infrared-reflective intermediate layer includes a reflective pigment dispersed in a matrix of one of the first thermoplastic material or the second thermoplastic material.

Described herein is a method for joining a first metal pipe with a second metal pipe, the pipes being joined together in an overlapping area by use of a two-component polyurethane adhesive that encapsulates the overlapping area, where the method includes the steps of:

(1) applying the two-component polyurethane adhesive onto an inner surface of a fixture;
(2) inserting one end of the first metal pipe into one end of the second metal pipe so as to form a pipe assembly having the overlapping area between the two ends, and putting the overlapping area of the pipe assembly into the fixture; (3) closing the fixture such that the overlapping area of the pipe assembly is fixed in the fixture, and such that the adhesive therein encapsulates the overlapping area of the pipe assembly; (4) curing the two-component polyurethane adhesive; and (5) optionally, removing the fixture from the pipe assembly.

A single layer/ply multi-use hose is contemplated. A thermoplastic polymer, such as polyurethane, is extruded through a woven tubular mesh of aramid fibers so as to encourage pillaring through gaps in the mesh of a sufficient amount to improve the overall durability and strength of the resultant hose. This wide diameter (at least 4 inches) and long continuous length (at least 300 feet) hose exhibits excellent durability (e.g., resistance to abrasion and/or punctures) and tensile ratios in excess of 2:1 so as to withstand tensile loads in excess of 100,000 pounds without delamination or bubbling within the hose wall.

A device and method for sealing or repairing a leaking and/or damaged location on an inner wall of a pipe, includes a volume-expandable bellow body configured to expand, with an increase in its volume, when the bellows body is positioned in the region of the leaking and/or damaged location in the interior of the pipe, with infiltration of a fluid, into a bellows-body interior. A carrier portion is formed on an outer surface of the bellows body, a resinated sealing mat being arrangeable on the carrier portion, the sealing mat being fastenable to the inner wall of the pipe, and being able to cure, in an expanded state of the bellows body in the region of the leaking and/or damaged location by being pressed against said-the inner wall. The device can also be used reliably in long-term use, such that the carrier portion is formed from Para rubber or silicone.

The present disclosure relates to articles and/or constructions with cohesive and to methods of making and using them. Many embodiments provide crush resistance in addition to customizability.

A tube container with a reduced resin usage amount compared to the prior art, and having the stiffness necessary for self-support of the container is provided. The tube container includes a tube-like body portion that is closed at one end and a spout portion mounted at the other end of the body portion, and the body portion is formed by a material composed mainly of paper.

A degradable containment includes an outer structural layer constructed of a pulp material, a central carrier layer constructed of a biopolymer, and an interior nanomaterial layer constructed of a nanomaterial.
