An electrical insulator apparatus and method of manufacturing an electrical insulator apparatus includes a core strength member which is positioned at least partially within at least one end-fitting. A thermoplastic exterior body having a plurality of spaced fins is injection-molded over the core strength member and at least partially over the at least one end-fitting. The core strength member is attached to the at least one end-fitting without a mechanical compression to the at least one end-fitting and without an adhesive between the core strength member and the at least one end-fitting. One or more mechanical upset structures formed on the at least one end-fitting prevent movements of the injection molded thermoplastic exterior body relative to the at least one end-fitting.

A medical device includes an outer polymeric tubular member and an inner tubular member. The outer polymeric tubular member includes one or more cuts formed therein to increase flexibility of the outer polymeric tubular member and includes an inner surface. The inner tubular member extends through the outer polymeric tubular member and has an outer surface in slidable contact with the inner surface of the outer polymeric tubular member. The outer polymeric tubular member is able to move relative to the inner tubular member as the medical device bends. In an example, the outer tubular member may be formed of a heat shrink material.

To provide an insole more easily fitting to a purchaser's foot. A method for manufacturing an insole comprises: a first step of forming a footprint resin portion 12 having a footprint shape having a predetermined thickness using a thermoplastic resin which melts at a predetermined temperature; a second step of performing shrink processing such that the footprint resin portion 12 is covered with a film, and thereafter vacuum packing the footprint resin portion covered with the film in a nylon polyethylene bag; a third step of heating the insole 10 manufactured through the first step and the second step at a predetermined temperature; and a fourth step of attaching the insole 10 having the footprint resin portion 12 melt by the third step to the inside of a shoe 2 of a user, and hardening the footprint resin portion 12 by leaving the shoe 2 stand for a predetermined time period while the user is wearing the shoe 2.

Provided are a crystalline and easily recyclable polyester heat shrinkable film, having a three-layer structure of layer A/layer B/layer C, in which the layer A is prepared by raw materials consisting of polyethylene terephthalate glycol copolymer (PETG), a functional master batch and polyethylene terephthalate (PET), the layer B is prepared by raw materials consisting of a modified PET, PET, a nucleating agent, a chain extender, and a foaming agent.

An electronic core for a metal card, such as a transaction card, having a metal core and a cured polymer top surface, is manufactured by a process in which a two-part polymer mixture is introduced to a reservoir holding the metal core in a process chamber, and then a partial vacuum followed by pressurization with inert gas are used to reduce the volume of voids in the partially-cured polymer mixture, followed by curing outside of the process chamber, and then the top surface is removed by a treatment operation, such as milling or etching, to form a reduced upper surface with less surface irregularities which is more substantially plan the original top surface.

A shrink cap for receiving a temperature-dependent switch. The shrink cap includes an open first end for sliding onto the switch and a closed second end which is closed by a welded or embossed seam that extends from an end face arranged in an area of the second end and resulting from the welded or embossed seam. The welded or embossed seam is formed in such a way that a formed section of the welded or embossed seam bears against the end face directly or with an interposed joining agent.

A tube body production method includes steps of: disposing a fiber body with respect to an outer circumferential surface of a mandrel so that the fiber body extends in an axial direction of the mandrel and an axial direction end portion of the mandrel has an exposed region where the fiber body is not disposed; disposing a fixing member with respect to the outer circumferential surface of the mandrel so that the fixing member covers the fiber body and extends to the exposed region, the fixing member having a tubular shape and configured to fix the fiber body with respect to the outer circumferential surface of the mandrel; and impregnating the fiber body with a resin on the outer circumferential surface of the mandrel and then heating the resin to mold the resin.

Provided is a polyester-based shrink film having excellent predetermined impact resistance and having a uniform shrinkage ratio near the shrinking temperature.

Provided is a tube body intermediate including: a carbon fiber disposed with respect to an outer circumferential surface of a mandrel so as to extend in an axial direction of the mandrel; and a fixing member having a tubular shape and disposed with respect to the outer circumferential surface of the mandrel so as to cover the carbon fiber. Also provided is a tube body production method including: disposing a fiber body with respect to an outer circumferential surface of a mandrel so that the fiber body extends in an axial direction of the mandrel; disposing a fixing member with a tubular shape with respect to the outer circumferential surface of the mandrel so that the fixing member covers the fiber body; and impregnating the fiber body with a resin on the outer circumferential surface of the mandrel and then heating the resin to mold the resin.

A non-crosslinked polymeric heat shrink tubing including poly(ether-block-amide) (PEBA) and methods for making such non-crosslinked polymeric heat shrink tubing is provided. The non-crosslinked PEBA heat shrink tubing disclosed herein finds application, e.g., as a processing aid and final component in the manufacture of catheters and other medical devices.
