Articles comprising an expanded polytetrafluoroethylene membrane having serpentine fibrils and having a discontinuous coating of a fluoropolymer thereon are provided. The fluoropolymer may be located at least partially in the pores of the expanded fluoropolymer membrane. In exemplary embodiments, the fluoropolymer is fluorinated ethylene propylene. The application of a tensile force at least partially straightens the serpentine fibrils, thereby elongating the article. The expanded polytetrafluoroethylene membrane may include a microstructure of substantially only fibrils. The articles can be elongated to a predetermined point at which further elongation is inhibited by a dramatic increase in stiffness. In one embodiment, the articles are used to form a covered stent device that requires little force to distend in the radial direction to a first diameter but is highly resistant to further distension to a second diameter (stop point). A large increase in diameter can advantageously be achieved prior to reaching the stop point.

Provided are a three-dimensional object additive manufacturing method and device, a storage medium and computer apparatus, where the method includes: forming a powder material layer by using a powder material; applying a liquid material onto the powder material layer according to layer printing data, where the liquid material dissolves at least part of the powder material, and the liquid material includes an active component capable of polymerization; and supplying energy to the powder material layer so that the active component in the liquid material is polymerized, the powder material itself is not polymerized and does not polymerize with the active component, and an area of the powder material layer to which the liquid material is applied is molded to obtain a slice layer of a three-dimensional object.

There are provided a substrate film, a laminate, and method of manufacturing a polarizing film. The present application provides a substrate film capable of effectively manufacturing a polarizing film having a thickness of about 10 m or less, about 8 m or less, about 7 m or less, about 6 m or less, or about 5 m or less and having an excellent function such as polarization performance, a laminate, and a method of manufacturing the same. According to the invention, it is possible to prevent tearing, curling, or the like from occurring in the elongation process and manufacture a polarizing film by easily elongating a polarization material such as a PVA-based resin.

Disclosed herein are compositions including a thermoformable sheet having three of more layers. Two layers include one or more monovinylidene aromatic monomer containing polymers which are impact modified by a rubber, one or more monovinylidene aromatic monomer and unsaturated nitrile containing copolymers, or a blend of one or more monovinylidene aromatic monomer containing polymers and a polyolefin, which exhibit resistance to environmental stress cracking. At least one of the two layers is an outer layer. An inner layer includes post-consumer recycled monovinylidene aromatic monomer containing polymers which are impact modified by a rubber, post-industrial recycled monovinylidene aromatic monomer containing polymers which are impact modified by a rubber. Optionally, the composition may include virgin monovinylidene aromatic monomer containing polymers which are impact modified by a rubber. Optionally, the composition may include an outer layer which is a gloss layer.

A semiconductive roller (1) is produced by: preparing a rubber composition containing a rubber component including an NBR and an EPDM in a mass ratio of NBR/EPDM=70/30 to 30/70, at least one selected from the group consisting of SAF, ISAF and HAF, sulfur, a peroxide crosslinking agent and a sulfenamide accelerating agent; extruding the rubber composition into a tubular body; crosslinking the tubular body in a vulcanization can or with the use of a continuous crosslinking apparatus; and forming an oxide film (5) in an outer peripheral surface (4) of the tubular body by irradiation with ultraviolet radiation with a shaft (3) inserted through the tubular body.

Methods and equipment for the recycling of carpet are disclosed that produce a clean fiber product suitable for industrial use. The methods allow the recovery of face fiber material, for example a polyester, polyolefin, or a polyamide, from carpets that includes a face fiber material, a polypropylene backing material, and an adhesive, and include the steps of mechanically impacting the carpet to break the bonds between the adhesive and the fibrous components, treating the fibrous components to remove adhesive granules from the fibrous components, and optionally separating the polypropylene backing from the face fiber. A clean adhesive/calcium carbonate product can also be produced from this process.

An example method of forming a biodegradable component includes extruding a mixture of biodegradable material and water through a die. The method further includes dividing the extruded mixture to form a plurality of biodegradable pellets. The method further includes forming the plurality of biodegradable pellets into a component. The water acts as a binding agent to bind the plurality of biodegradable pellets to one another.
