| 20080272513 | Process for the Coextrusion of Melt Streams of Different Composition - The invention relates to a method for coextrusion of at least two molten material flows having different composition by separating the molten material into at least two molten material flows, admixing additives in at least one of the molten material flows and bringing together the molten material flows by coextrusion in one or more extrusion tools. The method is particularly suitable for the production of PVB films with a color strip for composite glazings. | 11-06-2008 |
| 20090324889 | Embossed Plastic Films for Laminated Glass - The invention relates to a plastic film, at least one side of which is provided with a surface structure comprising parallel rows of elevations (a). Said elevations (a) are interconnected by means of webs (b) that are at least 10 percent lower than the elevations (a). The inventive films can be used for producing laminated glass. | 12-31-2009 |
| 20100086744 | PRODUCTION OF FILMS FOR COMPOSITE GLAZINGS BY MEANS OF INJECTION MOULDING OR INJECTION STAMPING METHODS - Foils based on softener-containing polyvinyl acetals are produced by injection moulding or injection stamping, and may preferably adopt a wedge-shaped cross-section not possible with extruded foils of polyvinyl acetal. The foils may be moulded to near net shape despite their very high area/thickness ratio, thus avoiding waste. | 04-08-2010 |
| 20100112267 | Method for Injection Molding of Thermoplastic Polymer Material with Continuous Property Transitions - The invention relates to a method for producing molded pieces with at least one continuous transition of physical and/or chemical properties by injection molding of thermoplastic polymer material wherein the continuous transition of the physical and/or chemical properties of the molded article is produced by modifying the portions of at least two melt streams, each with different physical and/or chemical properties, of the thermoplastic polymer material continuously and in opposite directions. Preferred produced molded articles can be films, in particular films suitable as interlayer for automotive laminated glass, and three-dimensional to components and molded articles. | 05-06-2010 |
| 20100193023 | PHOTOVOLTAIC MODULES COMPRISING PLASTICIZED FILMS BASED ON POLYVINYL ACETAL HAVING A HIGH SPECIFIC RESISTANCE - Plasticizer-containing films based on polyvinyl acetal having a glass transition temperature Tg of at least 20° C. are useful for the production of photovoltaic modules. The films preferably have a plasticizer content of a maximum of | 08-05-2010 |
| 20100193024 | PHOTOVOLTAIC MODULES COMPRISING PLASTICIZED FILMS HAVING A LOW MOISTURE ABSORPTION - Plasticizer-containing films based on polyvinyl acetals having a polyvinyl alcohol content of less than 20% by weight for the production of photovoltaic modules exhibit less water absorption at the edges of the modules. The films preferably have a glass transition temperature Tg of at least 20° C. and/or a plasticizer content of a maximum of 26% by weight. | 08-05-2010 |
| 20100206374 | PLASTICIZED FILMS BASED ON POLYVINYL ACETAL HAVING AN INCREASED GLASS TRANSITION TEMPERATUARE AND IMPROVED FLOW PROPERTIES - Plasticizer-containing films of polyvinyl acetal having a plasticizer content of a maximum of 26% by weight and containing a mixture of at least one high-viscosity polyvinyl acetal having a viscosity of 40-300 mPas and at least one low-viscosity polyvinyl acetal having a viscosity of 5-500 mPas are suitable for the production of photovoltaic modules. | 08-19-2010 |
| 20110229714 | INTERLAYER FILM FOR LAMINATED GLASS, METHOD FOR MANUFACTURING THE SAME, AND LAMINATED GLASS CONTAINING THE SAME - Provided is an interlayer film for laminated glass which is excellent in transparency, heat-shielding property, durability and electromagnetic wave permeability, and which has good adhesiveness with glass. Provided is an interlayer film for laminated glass made of a resin composition containing polyvinyl acetal (A), anhydrous zinc antimonate (B) and a plasticizer (C), wherein the anhydrous zinc antimonate (B) having a ZnO/Sb | 09-22-2011 |
