| 162138000 | Electrical or magnetic product characteristic | 6 |
| 20100032114 | Compositions containing expandable microspheres and an ionic compound as well as methods of making and using the same - This invention relates to composition containing expandable microspheres and at least one ionic compound and having a zeta potential that is greater than or equal to zero mV at a pH of about 9.0 or less at an ionic strength of from 10 | 02-11-2010 |
| 20100051220 | EXPANDABLE MICROSPHERES AND METHODS OF MAKING AND USING THE SAME - Expandable microspheres formed by suspension polymerization using a shot growth method are provided. The microspheres are formed of a continuous, gas impermeable shell surrounding a blowing agent. The shell includes a first polymer layer formed from primary monomers and a second layer that includes a chemically reactive monomer or a high Tg monomer. To form the microspheres, the primary monomers are polymerized in a reaction vessel to an approximate 90% polymerization, at which time a secondary monomer that is either a monomer having a Tg of at least 85° C. or a chemically reactive monomer, is added to the reaction vessel to drive the polymerization reaction to completion. The outer layer thus contains either a larger amount of the high Tg monomer or a chemically reactive monomer that possesses the ability to covalently bond a cationic species. The microspheres may be used in papermaking processes to increase the paper bulk. | 03-04-2010 |
| 20140034256 | CONDUCTIVE ARAMID PAPER AND METHOD FOR PRODUCING SAME - Provided is a conductive aramid paper comprising an aramid short fiber, an aramid fibrid, and a conductive filler, and having a density of 0.45 to 1.10 g/cm | 02-06-2014 |
| 20140231035 | PROCESS FOR OBTAINING MAGNETIC CELLULOSE PAPER AND THE RESPECTIVE PRODUCT - “PROCESS FOR OBTAINING MAGNETIC CELLULOSE PAPER AND THE RESPECTIVE PRODUCT” refers to a method for the production of magnetic paper and the respective paper, belonging to the field of paper products; in its usual form, the magnetic sheets, known as magnetic paper, are composed by magnetic blankets covered with cellulose sheets, and this setting results in a sheet of high thickness and high cost, in order to solve these disadvantages, the object of the present patent application was developed, referring to a magnetic paper, which differentiates itself from others because it has magnetic particles in its fibers, and also in its production process, more specifically in the magnetic cellulose sheet, in presentation is comprised by paper sheet ( | 08-21-2014 |
