Light fixtures (100, 200, 400, 500, 600, 700) are provided, including a lighting element (10, 20, 40, 50, 60, 70), an oriented crosslinked semi-crystalline polymer (12, 22, 42, 52, 62, 72) disposed adjacent to or connected to the lighting element, and a control mechanism (14, 24, 44, 64, 74). The control mechanism is in electrical communication with the lighting element (10, 20, 40, 50, 60, 70) and controls an energy output of the lighting element and a temperature of the oriented crosslinked semi-crystalline polymer (12, 22, 42, 52, 62, 72). Typically, when the control mechanism changes the temperature of the oriented crosslinked semi-crystalline polymer, the shape of the polymer changes. A method of making a light fixture (100, 200, 400, 500, 600, 700) is also provided. The method includes providing a lighting element (10, 20, 40, 50, 60, 70), forming a crosslinked semi-crystalline polymer (12, 22, 42, 52, 62, 72), and disposing the crosslinked semi-crystalline polymer adjacent to the lighting element (10, 20, 40, 50, 60, 70) or connecting the crosslinked semi-crystalline polymer to the lighting element. The method further includes electrically connecting a control mechanism (14, 24, 44, 64, 74) with the lighting element.

A flooring product includes a first oriented strand board layer, an acoustic barrier layer, and a second oriented strand board layer, where the acoustic barrier layer is secured between the first and second oriented strand board layers to form the flooring product. The plurality of flooring products can be positioned adjacently to comprise a complete flooring assembly. Such a flooring assembly can be facilitated by including features along edges of the flooring product for securing or engaging one flooring product to adjacent flooring products. For example, the flooring product can be arranged with one edge as a tongue and an opposing edge as a groove, where the tongue of one flooring product can be fitted into the groove of an adjacent flooring product to secure or engage the two flooring products together. In another example, edges of the flooring products can be arranged to form lap joints upon engagement.

A fluoropolymer composite film wire or cable wrap comprises an outer layer of expanded polytetrafluoroethylene (ePTFE) and an inner layer of melt processable fluoropolymer film. The inner and outer layers are laminated with each other in tape form, such as by the application of heat and/or pressure thereto. The fluoropolymer composite tape is wrapped about one or more wires or cables, and is heated or sintered after wrapping to bond the tape to the wire or cable, and bond the tape to itself at the seams.

A molding material comprising a fibrous reinforcement layer and a curable resin matrix. The fibrous reinforcement layer comprises a non-woven fabric comprising a single layer of unidirectional tows arranged at an angle greater than 0° in relation to the lengthwise direction of the fabric and a support structure for maintaining the arrangement of the tows.

The present invention is directed to a laminate having a first exterior surface and a second exterior surface, the laminate includes a first layer comprising a heat sealable material, a second layer comprising a cyclic olefin copolymer, a third layer comprising a metallic foil or metallized polymer material, and a fourth layer comprising a thermoplastic film or paper. The laminate provides high oxygen and/or moisture barrier properties and can withstand the corrosive effects of products containing solvents, halogens or strong acids and bases.

The waterproof sound-permeable membrane of the present disclosure is a waterproof sound-permeable membrane adapted to permit passage of sound and prevent ingress of water. The air permeability of the waterproof sound-permeable membrane, as expressed by Gurley number, is 20 seconds/100 mL or more. The water entry pressure of the waterproof sound-permeable membrane is 500 kPa or more. When a tensile strength at break of the waterproof sound-permeable membrane in a MD direction is denoted by T1 and a tensile strength at break of the waterproof sound-permeable membrane in a TD direction orthogonal to the MD direction is denoted by T2, a strength ratio (T1/T2) is in a range of 0.5 to 2.0.

A shrink film comprising a polyethylene-based film having a top surface, a bottom surface, and comprising one or more layers, wherein at least one layer of the polyethylene-based film comprises a low density polyethylene having a density of from 0.917 g/cc to 0.935 g/cc and melt index, I2, of from 0.1 g/10 min to 5 g/10 min, a linear low density polyethylene having a density of from 0.900 g/cc to 0.965 g/cc and melt index, I2, of from 0.05 g/10 min to 15 g/10 min, or combinations thereof, and optionally, a medium density polyethylene, a high density polyethylene, or combinations thereof, and a coating layer disposed on the top surface of the polyethylene-based film, wherein the coating layer comprises an adhesive and a near-infrared absorbent material.

A multilayer structure comprising at least one skin sealant layer, wherein the skin layer comprises a polyethylene having a crystallinity, C.sub.S; a tie layer which comprises a first polyethylene having a crystallinity, C.sub.T, wherein the tie layer is adhered to the skin layer; and a bulk layer which comprises a second polyethylene having a crystallinity, C.sub.B, wherein the tie layer is disposed between the bulk layer and the skin sealant layer; wherein C.sub.B>C.sub.T>C.sub.S; and wherein the layers are coextruded and the multilayer structure oriented by a semi-molten orientation process is provided. Also provided is a laminate comprising the multilayer structure and articles comprising the laminate.

A packaging film including an upper tab layer intermittently bonded to layers below it along a machine or longitudinal direction and suitable for forming a transverse easy opening feature in a formed package.

Methods for preparing oriented polymer tubes, such as biodegradable polymer tubes suitable for in vivo use, are provided herein. The disclosed methods provide alternatives to the typical extrusion/expansion methods by which oriented polymeric tubes for such uses are commonly produced. Advantageously, the disclosed methods can provide more homogeneous molecular orientation of crystallizable polymers within the tube walls, which can endow such polymeric tubes with enhanced strength (e.g., resistance to compression) and toughness.
