| 20100261809 | Polymer Composition with Uniformly Distributed Nano-Sized Inorganic Particles - The present invention provides a polymer composition wherein inorganic particles are uniformly dispersed at the nano level in the polymer without having said inorganic particles being surface-treated. It further provides a method for manufacturing a polymer composition wherein a co-aggregate which is obtained by uniformly mixing polymer dispersion with an inorganic particle colloidal solution and co-aggregating the polymer primary particles and inorganic particles which are heterogeneous particles, is separated from the solvent and dried so that the inorganic particles are uniformly dispersed at the nano level in the polymer; and the polymer composition which is obtained by said method. | 10-14-2010 |
| 20100197861 | Fluoropolymer Molding Process and Fluoropolymer Molded Product - A fluoropolymer molding process is provided for molding a mixture of at least two of fluoropolymers having different melting points at a temperature that is at or above the melting point of the fluoropolymer with the lowest melting point and is less than the melting point of the fluoropolymer with the highest melting point, and the resultant fluoropolymer molded product has excellent resistance to chemical and gas permeation and a low coefficient of linear expansion. | 08-05-2010 |
| 20100000771 | COPPER-CLAD LAMINATE, PRINTED-WIRING BOARDS, MULTILAYER PRINTED-WIRING BOARDS, AND METHOD FOR MANUFACTURING THE SAME - The present invention is to significantly improve copper-foil adhesion strength (copper-foil peel strength) without roughening or blackening a copper-foil surface, and thereby to provide a copper-clad laminate used favorably in a high frequency range. The copper-clad laminate ( | 01-07-2010 |
| 20090297751 | Fluoropolymer Blends with Inorganic Layered Compounds - Perfluoropolymer composites are provided which are obtained by dispersing layered-silicates having properties of swelling or cleaving in dispersion media in perfluoropolymers and having the ratio of the viscosity, V | 12-03-2009 |
