Patent application number | Description | Published |
20100010116 | Process for Preparation of Rubber Mixtures Containing Silicon Dioxide - Rubber mixtures are prepared by using, alongside the other constituents, pyrogenically prepared silicon dioxide in the form of crusts whose tamped bulk density (to DIN EN ISO 787-11) is from 185 to 700 g/l. | 01-14-2010 |
20100029818 | THERMOPLASTIC COMPOUND/MATRIX - Thermoplastic matrix/compound, comprising thermoplastic polymer and silanised, structurally modified, pyrogenically produced silica. | 02-04-2010 |
20100092710 | PROCESSING AID FOR THERMOPLASTIC POLYURETHANES - A processing aid is used in the processing of thermoplastic polyurethanes to give various articles including a self-supporting film. The processing aid contains a) 10-50% by weight of hydrophobized, at least partially aggregated, metal oxide particles selected from the group consisting of aluminium oxide, silicon dioxide and mixtures thereof, b) 20-75% by weight of one or more thermoplastic polyurethanes, c) 0.5-25% by weight of one or more isocyanates, d) 0.5-15% by weight of one or more compounds which act as lubricant and dispersant, the sum of the constituents a) to d) amounting to at least 90% by weight, based on a total weight of said processing aid. | 04-15-2010 |
20100179269 | PYROGENICALLY PREPARED SILICON DIOXIDE COMPACTED TO GIVE CRUSTS - Pyrogenically prepared silicon dioxide is compacted to give crusts, in that it is subject to preliminary de-aeration, and is compacted to give crusts, and the crusts are broken and, if appropriate, classified. The tamped bulk density (to DIN EN ISO 787-11) of the silicon dioxide compacted to give crusts is from 185 to 700 g/l. It can be used as filler in rubber mixtures. | 07-15-2010 |
20110034590 | THERMOPLASTIC ELASTOMERS - Thermoplastic elastomer, which comprises a fumed, hydrophilic or hydrophobic silica, which has been structurally modified and also a process for the improvement of the mechanical properties of thermoplastic elastomers. The thermoplastic elastomers are produced by preparing a masterbatch from the components (e.g. thermoplastic resin component and fumed silica) and compounding this with further thermoplastic elastomers. | 02-10-2011 |
20110112219 | THERMOPLASTIC ELASTOMER MIXTURES - Thermoplastic elastomer mixture which comprises at least one thermoplastic elastomer TPE, with the exception of a thermoplastic polyurethane TPU, and at least one filler from the group of precipitated silica, or precipitated silicate or carbon black. | 05-12-2011 |
20130020744 | PROCESSING AID FOR THERMOPLASTIC POLYURETHANES - Processing aid comprising a) 10-50% by weight of hydrophobized, at least partially aggregated, metal oxide particles b) 20-75% by weight of one or more thermoplastic polyurethanes, c) 0.5-50 by weight of one or more prepolymers comprising isocyanate groups the sum of the constituents a) to c) amounting to at least 80% by weight, based on the processing aid. | 01-24-2013 |
20130245173 | PROCESSING AID FOR THERMOPLASTIC POLYURETHANES - A processing aid is used in the processing of thermoplastic polyurethanes to give various articles including a self-supporting film. The processing aid contains a) 10-50% by weight of hydrophobized, at least partially aggregated, metal oxide particles selected from the group consisting of aluminium oxide, silicon dioxide and mixtures thereof, b) 20-75% by weight of one or more thermoplastic polyurethanes, c) 0.5-25% by weight of one or more isocyanates, d) 0.5-15% by weight of one or more compounds which act as lubricant and dispersant, the sum of the constituents a) to d) amounting to at least 90% by weight, based on a total weight of said processing aid. | 09-19-2013 |
