Abstract:
A composite core material and methods for making same are disclosed herein. The composite core material comprises mineral filler discontinuous portions disposed in a continuous encapsulating resin. Further, the method for forming a composite core material comprises the steps of forming a mixture comprising mineral filler, an encapsulating prepolymer, and a polymerization catalyst; disposing the mixture onto a moving belt; and polymerizing said encapsulating prepolymer to form a composite core material comprising mineral filler discontinuous portions disposed in a continuous encapsulating resin.
Abstract:
This invention relates to a roofing, cladding, or siding module, comprising an underlapping region extending from a head edge of the module and an exposed region extending from a foot edge of the module. The length of the foot edge defining the length of the module. The underlapping region is adapted to be substantially covered by the exposed region of an adjacent or overlapping module when installed on a building surface. The module is formed of at least one layer of extruded material. The layer so formed comprises at least 40% w/w filler and/or reinforcement, and one or more polymer(s).
Abstract:
The invention relates to the field of additive manufacturing, i.e. the manufacture of three-dimensional physical objects by the successive deposition (layering) of polymer materials, and more particularly relates to 3D jet printing techniques. The present method of printing on a 3D jet printer includes the controlled displacement of a 3D printer printing head, the supply of at least two filaments of a fusible material to the printing head, the heating of the filaments by temperature-controlled heaters, the alternate activation of one of the nozzles by means of a printer control module, and the pressurized supply of a filament to the active nozzle. During switching of the nozzles, the printer control module activates a printing head displacement module, which transfers one of the nozzles into an active position. The movement of a movable platform alters the position of the nozzles relative to a valve for the nozzles, closing off the openings of the inactive nozzles and freeing the opening of the active nozzle. Once the movable platform has been completely secured in an active nozzle activation position, the printer continues printing using the active nozzle. The technical result is an increase in the quality of the 3D models produced.

Disclosed are multilayer film structures including a layer (B) that includes a crystalline block copolymer composite (CBC) or a specified block copolymer composite (BC), including i) an ethylene polymer (EP) including at least 80 mol % polymerized ethylene; ii) an alpha-olefin-based crystalline polymer (CAOP) and iii) a block copolymer including (a) an ethylene polymer block including at least 80 mol % polymerized ethylene and (b) a crystalline alpha-olefin block (CAOB); and a layer C that includes a polyolefin having at least one melting peak greater than 125 C, the top facial surface of layer C in adhering contact with the bottom facial surface of layer B. Such multilayer film structure preferably includes (A) a seal layer A having a bottom facial surface in adhering contact with the top facial surface of layer B. Such films are suited for use in electronic device (ED) modules including an electronic device such as a PV cell.
Abstract:
A grip member and a method of making such a grip member including at least a polymerized region with two or more polymers. The first and second polymers cooperate to each form a portion of the top surface of the region. The region may be combined with a substrate to form a sheet. The sheet may be formed into a grip interface having any of a number of shapes including a panel shape. In the case of a panel shaped grip interface, the panel can then be attached to an underlisting sleeve to form the grip. Some versions of such a grip reduce impact shock and provide a feeling of tackiness in the manner of a spirally wrapped polyurethane-felt grip while allowing the use of multiple colors being polymerized together. The grip may be easily installed onto a golf club shaft and may further accommodate the use of polymers including various different characteristics including level of tackiness or durometer.
Abstract:
A protective film has a soluble polyimide polymer base layer and an exterior layer directly contacting the base layer exterior surface. The base layer is less than 12 microns thick, and is at least 2 meters long. The exterior layer includes at least one of a fluorinated polymer, a dielectric layer, one or more metallic layers, a metalloid layer, or a plurality a dielectric layers where each dielectric layer has a dielectric layer thickness that varies no more than 3%. The exterior layer or the base layer can also include additives, as desired.
Abstract:
A method of preparing a polymer film having an oriented dispersed material includes casting a multi-layer polymer solution having a first polymer solution layer and a second polymer solution layer where the second polymer solution layer is at least partially immiscible with the first polymer solution layer. The method further includes passing the multi-layer polymer solution through an electric field application zone, to thereby induce orientation of the dispersed material. A multi-layer polymer film can then be formed by drying the solvent from the multi-layer polymer solution. An apparatus for preparing polymer films includes a top electrode made from a flexible metal mesh coated with a non-stick, non-conductive coating.
