Embodiments described herein relate generally to systems and methods for manufacturing a master batch with a graphitic material dispersed in a polymer matrix. In some embodiments, a method for manufacturing the master batch can include combining the graphitic material with a polymer, adding a supercritical fluid to the mixture, and depressurizing the supercritical fluid to remove the supercritical fluid. In some embodiments, the method includes mixing the graphitic material and the polymer for a first time period to form a first mixture and transferring the supercritical fluid to the first mixture to form a second mixture. In some embodiments, the method includes mixing the second mixture for a second time period and depressurizing the second mixture to allow the supercritical fluid to transition to a gas phase.

A method of forming an insulated structure for an appliance includes forming a structural enclosure having an outer wrapper and an inner liner and an insulating cavity defined therebetween, forming an insulating powder material, compacting the insulating powder material to form a pre-densified core material, disposing the pre-densified core material within an insulating cavity, wherein the insulating cavity is defined between the outer wrapper and the inner liner and expressing at least a portion of the gas contained within the insulating cavity, wherein the insulating cavity is hermetically sealed to define a vacuum insulated structure.

Disclosed is a friction-reducing and anti-wear composite material for a wading kinematic pair and a method of preparing the same. The friction-reducing and anti-wear composite material is prepared from carbon fiber (CF) among inorganic fillers, polyimide (PI) and polyether ether ketone (PEEK). These three materials are wet-mixed, dried and placed in a mold followed by curing by a heat press. The cured product is cooled and demolded to obtain the CF/PI/PEEK friction-reducing and anti-wear composite material for a wading kinematic pair. Tribological properties of the PEEK material are enhanced due to synergistic effect arising from hybrid organic-inorganic filling. The friction-reducing and anti-wear composite material provided in the invention has significantly reduced friction coefficient and wear volume loss under the seawater environment.

A fully formed, freestanding, curvilinear geometric shaped, hashish cigarette product. A method of making the product consisting, substantially of hashish, the method comprising applying pressure to a collection of kief via a press for a period of time sufficient to form a pliable sheet of hashish having a thickness of 0.5 to 1 mm, cutting or trimming the pliable sheet into a substantially rectangular section, rolling the section of pliable sheet around an object having a curvilinear geometric shape at least one full rotation, and separating the rolled section of pliable sheet from the object, leaving only the fully formed, freestanding, curvilinear geometric shaped, hashish cigarette product.

A compression device, means for controlling the compression device, a drum having an inner chamber, means for rotating the drum, and first and second delivery devices for delivering first and second materials into the inner chamber of the drum while the drum is rotating. The compression device compresses the first and second material in the inner chamber of the drum while the drum is rotating about the center of the drum in response to the means for controlling the compression device. The apparatus may include a stirring device; and a means for controlling the stirring device; wherein the stirring device is configured with respect to the drum so that the stirring device can be moved up and down to a desired depth within the drum and rotates within the inner chamber of the drum to stir the first and second materials in the drum while the drum is rotating.

In addition, in a preferred embodiment of the crystalline radical polymerizable composition for sealing electrical and electronic component according to the present invention, the crystalline radical polymerizable compound is characterized by comprising one or more selected from unsaturated polyester, epoxy (meth) acrylate, urethane (meth) acrylate, polyester (meth) acrylate, -polyether (meth) acrylate, radical polymerizable monomer and radical polymerizable polymer.

Drug tablets that include a controlled release layer of a moisture-sensitive active agent are prepared with a lipidic matrix forming excipient, a water-soluble, channel forming excipient and a filler, each being non-hygroscipic. The tablets are formed in a process where the components are blended in the absence of moisture and in particulate form.

A resin-impregnated fiber bundle that can provide a molded article with a high surface impact strength is prepared by impregnating and integrating 100 parts by mass of a bundle of a fiber material (A) with 25 to 300 parts by mass of a thermoplastic resin (B). The fiber bundle has a flattened shape with a lateral cross-sectional shape having a major axis and a minor axis (length of the major axis>length of the minor axis). An average length (D1) of the major axis is 0.5 to 2.0 mm. An average flatness ratio (D1/D2), determined from the average length (D1) of the major axis and an average length (D2) of the minor axis, is 1.2 to 8.01. The fiber bundle has a length (L) of 11 to 50 mm, a ratio (L/D1) between L and D1 is 10 to 50, and a bulk density is 0.1 to 0.4 g/cm.sup.3.

A rigid nylon porous material sheet is produced by the adhesive bonding of kinked nylon fibers having lengths of 1 to 5 inches. These fibers are cut from melt spun nylon or harvested from clean carpet fibers by shearing. The adhesive used is glycol, which attacks nylon at 180 C. forming a gel on the surface of the kinked fibers, but does not attack the nylon fibers when the kinked fiber assembly is cooled to 150 C. to precipitate ultrafine nylon within the gel. The fiber assembly is heated to 160 C. to bond the nylon fibers. It is then washed in hot water to remove unused glycol. The other adhesive is polyurethane, which is applied to the kinked fibers using coupling agents of aqueous resorcinol and vinyl pyrrolidone.

A panel for forming a floor covering, where this panel includes a substrate including at least a layer of thermoplastic material, where the panel, above the layer, comprises at least also a printed decor and a translucent or transparent wear layer. The layer also includes at least individual fibers having a length greater than 1 millimeter, where the individual fibers are loose and freely distributed within the layer of thermoplastic material.
