A peelable heat-shrink tubing includes a base polymer comprising fluorinated ethylene propylene (FEP), and at least one fluoropolymer coextruded with the base polymer. The peelable heat-shrink tubing may have a haze between about 40% and 80%, inclusive, and/or a total luminous transmittance between about 70% and 85%, inclusive. In some embodiments, the haze may be between about 50% and 70%, inclusive, and/or the total luminous transmittance may be less than about 80%. The base polymer may comprise FEP NP-130 and constitute between about 87.5% and 92.5% by composition of the peelable heat-shrink tubing, inclusive, and the at least one fluoropolymer may comprise ethylene tetrafluoroethylene (ETFE) and constitute between about 7.5% and 12.5% by composition of the peelable heat-shrink tubing, inclusively. In some embodiments, the at least one fluoropolymer may comprise 7.5% of ETFE and 5% of perfluoroalkoxy alkane (PFA), each by composition of the peelable heat-shrink tubing, inclusive.

The invention provides a heat-shrinkable polyester film characterized by (1) a hot-water heat shrinkage rate in a width direction of the film of 40%-80% by immersing the film in hot-water at 90 C. for 10 seconds; (2) a hot-water heat shrinkage rate in a longitudinal direction of the film of 5%-10% by immersing the film in hot-water at 90 C. for 10 seconds; (3) a maximum peak height Sp on at least one surface of the film of 0.8-3.0 m; (4) an arithmetical mean height Sa on at least one surface of the film of 0.03-0.2 m; and (5) a degassing time for removing air from between the two identical polyester films is 14 seconds or less, wherein the films are formed by stacking a front surface of the one film on a back surface of the other film.

This ball joint is provided with: a ball stud, one end being fastened to a suspension device/stabilizer, and the other end having a ball part; a housing that rotatably supports the ball part of the ball stud; and a ball seat provided so as to be interposed between the housing and the ball part, the ball seat having an inner spherical part for accommodating the ball part. The ball seat is provided to the housing by insert injection molding. The inside diameter dimension of the inner spherical part formed by separate injection molding is set to a dimension corresponding to the anticipated amount of molding shrinkage of the resin during the insert injection molding.

To provide a composite preform that can ensure that worsening of the appearance of a surface of a plastic member caused by near-infrared heating prior to blow molding is effectively prevented and that an inner preform is efficiently heated. The composite preform of the present invention includes a preform and a heat-contractive plastic member, the preform including a mouth part; a trunk part linked to the mouth part; and a bottom part linked to the trunk part, and the heat-contractive plastic member being disposed so as to surround the outside of the preform and including at least a colored layer that contains a resin material and a colorant, wherein the heat-contractive plastic member has a near-infrared transmittance of 50% or higher.

A tape-shaped product and a belt for a ball chain are provided. A tape-shaped product of synthetic resin includes a tape of a thermoplastic resin, and a preliminarily stretched fibrous member of a thermoplastic resin contained therein along longitudinally parallel edges or in proximity thereto of the tape. A belt for a ball chain, includes a tape-shaped product of synthetic resin formed by injection molding, together with a fibrous member as an insert of a resin of the same kind as that of the fibrous member so that the fibrous member is disposed along the longitudinal edges or in proximity thereto, ball-insetting holes are disposed at equal intervals, and ball-retaining projections are disposed around the holes.

The combination of 3D printing technology plus the additional dimension of transformation over time of the printed object is referred to herein as 4D printing technology. Particular arrangements of the additive manufacturing material(s) used in the 3D printing process can create a printed 3D object that transforms over time from a first, printed shape to a second, predetermined shape.

A portable device for attaching a connector to an optical fiber, the optical fiber having an end, the device comprising means for receiving the optical fiber at the end of the optical fiber; and a connector station for autonomously attaching the connector to the optical fiber.

A cylindrical shrink label is provided with a heat-shrinkable label base material; and a joint formed by cylindrically forming the label base material so that the edges thereof overlap, and then solvent welding the inner surface of the outside edge, which is positioned on the outside of the cylinder, and the outer surface of the inside edge, which is positioned on the inside of the cylinder. A resin layer, which is soluble in a hot alkaline aqueous solution, is formed on the abovementioned inner surface and/or the abovementioned outer surface, which form the joint.

Examples are disclosed that relate to textile coverings for electronic devices and methods for manufacturing textile coverings for electronic devices. In one example, a textile covering for an electronic device comprises one or more structural fibers woven into a seamless tube, the seamless tube configured to encircle at least a portion of the electronic device. The textile covering also comprises one or more heat-shrink fibers and/or one or more adhesive fibers woven into the seamless tube. The heat-shrink fibers shrink when the seamless tube is heated above a threshold temperature, thereby constricting the seamless tube around the electronic device. The one or more adhesive fibers adhere the textile covering to the electronic device.

Protective coverings herein have a coated woven material with a first edge parallel with a warp direction and a second edge opposite the first edge, and have a first edge band proximate the first edge and a second edge band proximate the second edge. The coated woven material has a woven scrim made of a plurality of weft tapes and a plurality of warp tapes, but the warp tapes positioned in the first and second edge bands are high-shrinkage warp tapes and the warp tapes positioned in between the first and second edge bands have a shrinkage that is less than a shrinkage of the high-shrinkage warp tapes, and has a coating on at least one major surface of the woven scrim. The plurality of high-shrinkage warp tapes shrink upon application of heat. Methods of covering a load, such as stacked lumber, with the protective covering are also disclosed.
