摘要： Parts made by additive manufacturing are often structural in nature, rather than having functional properties conveyed by a polymer or other component present therein. Printed parts having piezoelectric properties may be formed using powder particulates comprising a thermoplastic polymer and piezoelectric particles, wherein the piezoelectric particles are located (i) in the thermoplastic polymer at an outer surface of the powder particulates, (ii) within a core of the powder particulates, or (iii) combinations thereof. Additive manufacturing processes, such as powder bed fusion of powder particulates, may be employed to form printed objects in a range of shapes from the powder particulates. Melt emulsification may be used to form the powder particulates.

摘要： The present invention generally relates to a method for manufacturing phase change material (PCM) pellets. The method includes providing a melt composition, including paraffin and a polymer. The paraffin has a melt point of between about 10° C. and about 50° C., and more preferably between about 18° C. and about 28° C. In one embodiment, the melt composition includes various additives, such as a flame retardant. The method further includes forming the melt composition into PCM pellets. The method further may include the step of cooling the melt to increase the melt viscosity before pelletizing. Further, PCM compounds are provided having an organic PCM and a polymer. Methods are provided to convert the PCM compounds into various form-stable PCMs. A method of coating the PCMs is included to provide PCMs with substantially no paraffin seepage and with ignition resistance properties.

摘要： Speriodal polymer beads having a uniform size are prepared by polymerizing uniformly sized monomer droplets formed by dispersing a polymerizable monomer phase over a cross-flow membrane into an aqueous phase. A shear force is provided at a point of egression of the polymerizable monomer phase into the aqueous phase, the direction of shear substantially perpendicular to the direction of egression of the monomer phase. The polymer beads can be employed in applications where beads having uniform diameters of 10 to 180 μm are useful.

摘要： A method and a device for producing superficially crystalline spherical granules by means of air-cooled hot die face pelletizing in a cutting chamber. A crystallizable plastic material can be melted and then extruded through a perforated plate. During the air-cooled hot die face pelletizing, at least one cutting blade can be moved relative to the perforated plate. The perforated plate can be temperature-controlled while maintaining a viscosity of the plastic material within nozzle openings. A superficial cooling to a crystal nucleation temperature of the dry-cut granules is performed by means of a centripetally inflowing process gas. The crystal nucleation temperature is below an optimum crystal growth temperature and above a glass transition temperature. By controlling the quantity of process gas at an adiabatic temperature, an average granule temperature is maintained in a range of an optimum crystal growth temperature.

摘要： Provided are: a powdered material for slush molding; and a manufacturing process therefor. The powdered material is less odorous, exhibits excellent powder fluidity, and does not suffer from troubles resulting from the sliding-down or agglomeration of a pigment even when the resin particles have been pigmented on the surfaces thereof. Thus, the powdered material ensures high productivity. The powdered material is a powdered polyurethane urea resin composition which comprises (D) a polyurethane urea resin that has a total content of bimolecular condensate of acetone, bimolecular condensate of methyl ethyl ketone, and bimolecular condensate of methyl isobutyl ketone of 1,000 ppm or less and (N) an additive, wherein the polyurethane urea resin (D) takes the form of thermoplastic polyurethane urea resin particles (P) that have a volume-mean particle diameter of 20 to 500 μm and that have protrusions and recesses on the surfaces. The powdered polyurethane urea resin composition is manufactured by a manufacturing process which includes a step of mixing (A) an isocyanato-terminated urethane prepolymer with (B) an alicyclic diamine and/or an aliphatic diamine in an aqueous medium by stirring to form the resin particles (P).
