| 20120061870 | METHODS FOR MICROCELLULAR INJECTION MOLDING - In a method of microcellular injection molding, a polymer and a supercritical fluid are processed. A condition of processing the polymer and/or the supercritical fluid is adjusted to control a weight of a plastic part and/or a surface characteristic of a plastic part produced. In another method of producing a plastic part using microcellular injection molding, a polymer is heated and melted and a supercritical fluid is added thereto. The resulting mix is a single-phase polymer-gas solution comprising the polymer and the supercritical fluid. The polymer and/or the supercritical fluid are adjusted to control the weight of the plastic part and/or a surface characteristic of the plastic part. Once adjusted, the melted polymer with the supercritical fluid is injected into a mold. Upon injecting the melted polymer and supercritical fluid, a pressure drop causes the supercritical fluid to nucleate in the melted polymer, thereby causing nucleation of bubbles. | 03-15-2012 |
| 20120061867 | POLYMER PELLETS CONTAINING SUPERCRITICAL FLUID AND METHODS OF MAKING AND USING - A process for the manufacture of a plastic part, the process comprising providing a polymer, heating the polymer, introducing a gas or supercritical fluid into the polymer, mixing the polymer and the gas to produce a first melt, extruding the first melt, pelletizing the extruded first melt to form pellets, transforming the pellets into a second melt, and molding the second melt to form the plastic part. In pelletizing the first melt, individual cells of gas are included in the resulting pellets. Before the cells can nucleate, the polymer is solidified to keep the gas contained therein. After the polymer is pelletized, the pellets are considered to be unfoamed. In molding the second melt to form the plastic part, nucleation of the cells is initiated through favorable process conditions and/or additional cell nucleating agents, thereby resulting in the second melt being foamed. | 03-15-2012 |
| 20110173738 | POLYMER LATEX COMPOUND - A polymer latex composition has an acrylonitrile component, a polychloroprene component, and a natural latex component. When these components are blended together and formed into a film, the film exhibits a resistance to ozone that is greater than a resistance to ozone of materials in which acrylonitrile is not included. Furthermore, the combination of acrylonitrile and chloroprene imparts a synergistic effect to the composition with regard to ozone resistance. The film can be formed into a glove having a resistance to ozone that is improved over the resistance to ozone of gloves not including acrylonitrile. The glove may include an antimicrobial agent. | 07-21-2011 |
| 20100268182 | TAMPON PLEDGET WITH IMPROVED BY-PASS LEAKAGE PROTECTION - A tampon pledget is made by assembling one or more pads in a pad compression configuration, radially compressing the pad compression configuration in a traverse direction into a cylindrical form, and axially compressing the cylindrical form in a direction along a vertical axis to form the tampon pledget. In one embodiment, the axial compression is performed as a pressure is applied to at least one of a first and a second end of the cylindrical form. In one aspect of the present invention, the formed tampon pledget has an absorbent capacity as measured by the syngyna test of between about 6.0 grams to 9.0 grams and a density of about 0.4603 grams/cubic centimeter. In another aspect of the invention, the formed tampon pledget has an absorbent capacity as measured by the syngyna test of between about 9.0 grams to 12.0 grams and a density of about 0.4755 grams/cubic centimeter. | 10-21-2010 |
| 20100036309 | LOW ABSORBENCY TAMPON PLEDGET AND METHOD OF TESTING - An improved light duty tampon is defined by a quantity of an absorbent material arranged in substantially cylindrical form and having a lower dry bulk density, lower expansion values, and lower fluid absorption rates, as compared to similar absorbent capacity tampon pledgets. A method of testing a light duty tampon includes determining absorbent capacity, density, radial expansion width, and expansion rate of the tampon. | 02-11-2010 |
| 20090234268 | TAMPON PLEDGETS WITH IMPROVED LEAKAGE PROTECTION - An increased absorbency tampon pledget with an absorbent capacity of 15-18 grams and an increased dry bulk density has a density of at least 0.20 g/cc and can be housed in a smaller applicator than typically provided with commercially available increased absorbency applicator tampons. The increased dry bulk density provides better leakage protection, placement control, and user comfort. | 09-17-2009 |
