| 20090221744 | PROCESS FOR PREPARING A HIGH-COHESION PSA - A process is presented for the preparation of a high-cohesion non-thermoplastic pressure-sensitive adhesive (PSA) on the basis of elastomers, in which neither a solvent nor thermoplastic additives are used and yet thermal breakdown during compounding is kept low. This is achieved through the addition of a vaporizable process agent which is introduced into the adhesive after the constituents have been premixed and which undergoes flash vaporization therein, thereby quenching the adhesive. Furthermore, the use of water to cool the adhesive is proposed, and the high-cohesion PSA thus produced, and also a pressure-sensitive adhesive tape with an adhesive of this kind, are presented. | 09-03-2009 |
| 20090289381 | METHOD OF ENCAPSULATING OPTOELECTRONIC COMPONENTS - Method of encapsulating optoelectronic components, by embedding the components to be encapsulated between a first transparent polymer layer and a second polymer layer, which is filled with unactivated foaming agent, and then activating the foaming agent, so that the two polymer layers join to one another, in particular weld to one another, and the components are enclosed between the two polymer layers. | 11-26-2009 |
| 20100147443 | ADHESIVE TAPE, PARTICULARLY FOR BONDING PHOTOVOLTAIC MODULES - The present invention relates to the use of an adhesive tape for adhesively bonding photovoltaic modules, more particularly for adhesively bonding a PV laminate in the frame of a PV module, where the adhesive tape has at least one adhesive layer and where there is at least one polymer layer comprising a foaming agent. | 06-17-2010 |
| 20110120615 | RADIATION-CROSSLINKABLE FOAMED SELF-ADHESIVE BASED ON VINYLAROMATIC BLOCK COPOLYMERS - Self-adhesive consisting of a mixture having at least one tackifier resin, expanded polymeric microbeads and a polymer blend made up of thermoplastic and/or non-thermoplastic elastomers with at least one vinylaromatic block copolymer containing a fraction of more than 30% by weight of 1,2-linked diene in the elastomer block. | 05-26-2011 |
| 20110256395 | Pressure-sensitive adhesives based on natural rubber and polyacrylates - A pressure-sensitive adhesive consisting of a homogeneous mixture of at least one natural rubber component and at least one polyacrylate component displays significantly improved properties in cohesion and aging and weathering resistance compared to the individual components. Particularly good properties are achieved when the adhesive contains x% by weight of at least one natural rubber component, y% by weight of at least one polyacrylate component, v% by weight of at least one adhesive resin component and w% by weight of additives, where 10≦×x≦80, 10≦y<95, 0≦v≦50, 0≦w≦10 and x+y+v+w=100. A single- or double-sided adhesive tape consisting of at least one support and at least one layer of such a pressure-sensitive adhesive therefore likewise has good cohesion and aging resistance properties. | 10-20-2011 |
| 20110281964 | Process for preparing foamable polymer compositions, process for preparing foamed polymer compositions therefrom, foamed polymer compositions and adhesive tape therewith - The invention relates to a process for preparing a foamed polymer composition using expandable hollow microbeads,
