Kunststoffe international, 2005-11-21, Attractive and Robust
...otential outdoor applications. The chemical resistance extends to cleaning agents, thawing salt and de-icing sprays, for example. A further polyamide undergoing trials for decoration purposes is a semi-aromatic, micro-crystalline polyamide (grade: Trogamid CX7323). This is a highly-transparent product with outstanding chemical resistance and excellent strength at low temperatures. Decoration Techniques Both classical and highly modern printing techniques are employed for decorating films. Thes...
Kunststoffe international, 2005-11-21, High-performance Polymers: Metal Substitution and Miniaturisation
... low internal stresses, while avoiding birefringence. The innovative polyethersulphone successfully passed its first test run as a display sheet in a mobile phone. Polyamides for Covers, Armrests and Automotive Parts “Trogamid CX was conceived because amorphous plastics generally offer little resistance to chemicals,” is how Degussa justifies the development of its CX 7323 grade polyamide. The stress cracking-resistant moulding compound is intended to produce lamp covers that are much more im...

...ss achieved with the two polyamides, coupled with a high bursting pressure. Together with their low sliding friction, these properties ensure that the catheter can be applied gently and without any pain, as far as possible. Transparent and Robust Trogamid CX is the name of a semi-crystalline polyamide whose crystallites are so small, thanks to the selective combination of monomers, that they do not scatter visible light – a property denoted micro-crystallinity. Trogamid CX is thus a crystal cl...
Kunststoffe international, 2005-11-21, Nanoscale NIR Absorbers: Permanently Mark Highly Transparent Plastics
... largely on the chemical composition of the polymer and the laser parameters. Because of the difference in the refractive index, the marking is easily recognised and exhibits high contrast and sharp edges. Fig. 2 shows the transmission curve of Trogamid CX7323 containing NIR absorbers. Examples: Transparent PA and PMMA While highly transparent, semi-crystalline polyamide (PA) based on cycloaliphatic diamines (grade: Trogamid CX7323) can be laser-marked without an additive, the marking exhibits l...

...echnology has the potential to increase the aesthetics of transparent plastics, e.g. for architectural uses. It is not only acrylic glass that carries the potential for engraving high-resolution 3D motifs in parts. Other materials, such as Trogamid (semicrystalline polyamide), can also be used.

Multiple stopcocks produced from PA PACM 12 (grade: Trogamid CX, manufacturer: Degussa, Düsseldorf/Germany) and polycarbonate were tested for their suitability and stress cracking resistance in contact with the following medical substances: cyclosporin, lipids, phenytoin sodium salt and propofol 1%. The...

By way of example, Fig.4 shows the measured transmission and reflection as well as the absorption calculated from these values for a 2mm-thick test specimen of unpigmented PA6-3-T (grade: Trogamid T5000, manufacturer: Evonic) as a function of wavelength between 400nm and 2,600nm. The spectrum exhibits three regions characteristic of plastics: At visible and near-infrared wavelengths up to 1,500nm, many plastics are more or less transparent (translucent or opaque), and...

... Germany, to evaluate the influence of these additional test parameters. Heat aging tests were conducted on more than ten grades – PA12, PA612, PA 6-3-T – some plasticized, impact-modified or reinforced (grade: Vestamid and Trogamid, manufacturer: Evonik). The indicative properties investigated were the results of tensile tests according to ISO 527, impact tests according to ISO 179 (notched and unnotched) and penetration tests according to ISO 6603. The results of this evaluation are not the su...

The titanium hinge on the temple joint of the first generation of Lensbond lenses has now been replaced by polyamide as well. The properties of the materials employed meet the unique needs with pinpoint accuracy, i.e. the material for the nose pad is flexible whereas that for the temple is stiff. The path to property-optimize...

For example, Evonik found a new substitute material of polysulfon (PSU). Its Trogamid RS6121 is a transparent and steam-sterilizable polyamide with a density 20 % lower than that of PSU. Steering in the same direction, Ems introduced to the market its new Grilamid TR material, which features a transparency similar to that of polycarbonate,...
