| Polymer-Chemie at K in Düsseldorf  Newly developed glass fibre-reinforced PVC compounds as well as compounds with improved general properties will be the focal point of the presentation of Polymer-Chemie GmbH, Bad Sobernheim, at this year's "K" in Düsseldorf. The trade fair for the plastics and rubber industry will occupy all of the exhibition halls at the Düsseldorf Trade Fair Center from Wednesday, 24 October to Wednesday, 31 October 2007. Among the innovations of Polymer-Chemie's Business Unit PVC Compounds will be both glass fibre-reinforced PVC compounds and, as a première, long glass fibre-reinforced compounds with PVC as the matrix material. For example, the newly developed long glass fibrereinforced PVC compound – the strands are of pellet length – can be used for the production of window frame reinforcing sections capable of replacing parts hitherto manufactured in metal.Besides their weight-saving advantage, these reinforcing sections not only improve thermal insulation but also open up new design possibilities. The scope of R & D work also includes compounds with sustainable raw materials. A further exhibition theme is "Fillers with a Function". In this context, Polymer-Chemie's presentation will include new graphite-filled compounds for a whole range of applications, from packagings for electronic products through to moulded structural parts for use in the construction industry. All PVC compounds can be processed by the usual methods, e.g. extrusion and injection moulding. Especially in the case of long glass fibre-reinforced compounds, gentle but thorough dispersion is absolutely essential. Homogeneous dispersion – without causing excessive breakage of the fibres – is a decisive factor for such part properties as high impact resistance, strength, rigidity and heat resistance. Backed by many years' compounding know-how, Polymer-Chemie has developed a process that ensures an uniform embedding of the strands in the matrix, beginning with a special pretreatment of the continuous strands prior to their introduction into the compounding line, where they are gently worked into the PVC matrix. The resulting rod-shaped pellets feature strands of full pellet length. These compounds are available under the trade name SorVyl with different pellet lengths and hence different strand lengths and different glass fibre contents. write your comments about the article :: © 2007 Construction News :: home page |
