| 20100300572 | ENCASED PIPELINE - A pipeline laid trenchlessly and/or without a sand bed is produced using a metallic conduit which is encased with an extruded layer of a polyamide moulding material. In this way, the durability of the outer shell required for trenchless laying techniques without a sand bed is ensured. | 12-02-2010 |
| 20100300573 | USE OF A POLYAMIDE MOLDING COMPOUND FOR LINING CONDUITS - In a method for the introduction of an inliner into a pipe or a pipeline, where the external diameter of the inliner is greater than the internal diameter of the pipe or of the pipeline, and where the action of an external force is used to reduce the cross section of the inliner prior to the introduction, the inliner is composed of a polyamide moulding composition which comprises at least 50% by weight of polyamide which is not PA11. The recovery behaviour of said polyamides is similar to that of polyethylene usually used for this purpose. | 12-02-2010 |
| 20110165358 | PROCESS FOR PRODUCING A MOLDING COMPOSITION OR A MOLDING WITH AN INCREASE IN THE MELT STIFFNESS - A polyamide moulding composition is condensed up in the melt by means of a masterbatch containing a compound having at least two carbonate units and also a polyetheramide in which at least 50% of the end groups are present as amino end groups, whereupon the melt mixture is discharged and solidified to give a moulding composition or a moulding. The product obtained has an increased amino end group content and consequently an improved hydrolysis resistance. | 07-07-2011 |
| 20110209768 | USE OF A COMPOSITION FOR CONTACT WITH SUPERCRITICAL MEDIA - A moulding composition which comprises at least 50% by weight of the following constituents: | 09-01-2011 |
| 20110217559 | JOINING OF MOULDINGS OF DIFFERENT POLYAMIDE COMPOUNDS - A moulding compound for joining two mouldings each made of a PA11 and/or PA12 moulding compound contains at least 50% by weight of a polyamide component so chosen that it is preparable from linear aliphatic diamines and dicarboxylic acids and/or lactams or ω-aminocarboxylic acids, there being 11 to 12 carbon atoms present per carboxamide group in the repeating units, and, furthermore, this polyamide component containing not more than 80% by weight of either one of the polyamides PA11 and PA12. With this compound a firm weld is obtained both to a PA11 moulding and to a PA12 moulding. | 09-08-2011 |
| 20110244209 | TRANSPARENT MOLDING COMPOSITION - A polyamide molding composition which can be used for production of a printable or printed item contains a) at most 90 parts by weight of a polyamide obtained from a lactam or from an amino carboxylic acid having at least 10 carbon atoms; and b) from 10 to 100 parts by weight of PA1010, wherein a total of components a) and b) is 100 parts by weight. | 10-06-2011 |
