Kunststoffe international, 2005-11-21, Continued Strong Growth: PET in Beverage Packaging
Trend Report: Engineering Plastics PET in Beverage Packaging Continued Strong Growth. The raw material of PET has undergone a change. Modified product grades now permit even faster injection moulding cycles and higher cycling rates in bottle production. In addition, the grade of PET (in combination with different barrier materials) and the bottle design have been aligned to the bottled product. Kajetan Müller Frank Welle Polyethylene terephthalate (PET) is continuing to show high growth in th...

Kunststoffe international, 2005-11-21, Film Extrusion: PET Extrusion without Pre-drying?
Extrusion PET Extrusion without Pre-drying? Film Extrusion. The degassing technology represents a realistic alternative to pre-drying or at least a useful addition to it. Studies show that the processing of undried granules is possible on a single-screw extruder with the aid of degassing. Walter Michaeli Torsten Schmitz The market for polyethylene terephthalate (PET) over the last few years has been characterised by rapid growth. Everyone seems to be talking about the material and, not too lo...

Kunststoffe international, 2005-11-21, Innovations Today and Tomorrow: Polypropylene for Flexible Packaging
Packaging Polypropylene for Flexible Packaging Innovations Today and Tomorrow. The continuous improvement of flexible plastic packaging – driven primarily by the wishes of the consumer – is being helped along by the constant further development of polypropylene. With both flexible and rigid films – and especially with transparent cast film – enormous progress has been made in the last ten years. An important new impetus has also been provided by the development of new easy-to-open, easy-to-han...

Kunststoffe international, 2006-01-30, Plastics for Medical Technology: Long Life Ensured
Special. Long Life Ensured. Plastics for Medical Technology. In recent years, various raw material manufacturers have introduced new grades of plastics specifically tailored to applications in the medical segment. One aspect that is frequently overlooked, however, is that only if the formulation for these materials remains unchanged over a long period of time can the converter fully recoup the high investment needed for the particularly complex development of his products. Medical technology ...

Kunststoffe international, 2007-08-14, A Route to Cost-effective Photovoltaic Technology
A Route to Cost-effective Photovoltaic Technology Polymer Solar Cells The most recent branch of photovoltaics research involves polymer solar cells based on organic conjugated functional polymers. With semiconductor layer thicknesses around one-thousandth the thickness of a human hair, these polymer solar cells represent the thinnest of all thin-layer technologies. With their comparatively low investment and production costs, they are highly attractive. Steffi Sensfuss et al. Photovoltai...

Kunststoffe international, 2007-08-14, Direct Production of Packaging Films
Direct Production of Packaging Films Compounding A technology was developed years ago for preparing PET for flat-film extrusion that involves neither pre-drying the materials, nor crystallizing and agglomerating the recycling materials. In order to accommodate market demand, the process has meanwhile undergone steady further development to include other materials. Werner Wiedmann Sabine Schönfeld Compounding systems can be classified according to their design features, such as the number ...

Kunststoffe international, 2007-10-21, Flexible Where It Matters
Flexible Where It Matters Fluid Lines Fluid-assisted injection technology is a cost-effective way of manufacturing highly integrated hollow articles. The combination of this technology with multicomponent injection molding allows fluid pipes to be manufactured with mechanical, optical, electrical, chemical or thermal properties that differ from one segment to the next. This allows the functional range of parts to be significantly extended. Walter Michaeli Andreas Neuss Fluid-carrying hollo...

Kunststoffe international, 2008-04-14, Performance Enhancements for Highly Filled Compounds
Performance Enhancements for Highly Filled Compounds Dispersing Additives Compounds with high filler loadings are difficult to process. This results in sub-optimal dispersion of the fillers in the polymer matrix, which also has a negative influence on the mechanical properties. A new additive concept now allows processing and properties to be improved. Bärbel Gertzen Jörg Garlinsky Fillers are used in polymers in many ways to improve properties or reduce costs. A wide range of various diff...

Kunststoffe international, 2011-09-23, The Torque of the Twin Screw
At K2010, Coperion GmbH, Stuttgart, Germany, formerly Werner & Pfleiderer, introduced its ZSK Mc18, a new, even more powerful generation of compounding extruders for plastics (Fig. 1). The basic goal behind the further development of these co-rotating, closely intermeshing twin screw compounders was to strongly enhance user benefit. The ZSK Mc18 now offers a unique combination of top productivity, top product quality and top flexibility. The essential factor in this new development was a 30 ...

Kunststoffe international, 2014-03-21, MagnetPIM: One-Shot Production of Sintered Magnets
MagnetPIM is a process for producing complex multi-polar sintered magnets without the need for any assembly steps. The resulting scope for miniaturization and integration of functions opens up vast application potential, especially for sensor and drive technology. There are currently two main ways to manufacture magnetic components. Where high levels of magnetism are required, compression molding, optionally followed by sintering of the components, is the method of choice. However, geometric con...
