... ethylene and norbornes. By modifying the norborne content, it is possible to vary the properties of the material over a broad range and align them to the specific requirements of the application in question. Hence the heat resistance of the COC Topas can be set at between 60 and 170°C, as required. Since Topas was launched on the market four years ago, the crystal-clear transparency, high purity and low water-vapour permeability of the COC has repeatedly come under close scrutiny. These charact...

An extended transmission range to below 200 nm is provided by the special grade Topas 8007X10. This is an essential prerequisite for its use in UV spectrosocopic analysis. In conjunction with COCs' high resistance to aqueous and polar organic media, such as acetone, ethanol, DMSO and acetonitrile, applications in medical dia...

Since April, Polyplastics has been marketing Ticona's Topas COC material in the entire Asia-Pacific region. The Japanese company is intending to increase sales of this high-tech material, which is used inter alia in medical engineering and optical applications and also in the packaging industry, to 2000t by...
Kunststoffe international, 2005-11-21, High-performance Polymers: Metal Substitution and Miniaturisation
...The reason for this is the increased demand for printable films for PET beverage bottles, whose production volumes increased hugely following the introduction of the deposit on cans. The cycloolefin copolymer Topas 9506F-04 offers Ticona customers a shrink film with good printing properties, high stiffness for fitting on the bottles, a durable vapour barrier and 80% shrinkage, which is essential for irregular shaped bottles. The glass-like UV transmission of COC makes the copolymer ideal for med...

These benefits contributed to the decision of the glass specialist Schott to introduce a new series of prefillable syringes manufactured from Topas COC at the beginning of 2004. There is also great potential for diagnostic applications. These range from microtiter plates, lab CDs, biochips, cüvettes, and graduated vessels to tubes, pipettes and much more. The combination of transparency, purit...
Kunststoffe international, 2005-11-21, Production Monitoring: Particle Monitoring on the Extruder
...The New Particle Sensor The Leibniz Institute of Polymer Research in Dresden has developed an innovative laser-optical particle sensor in close cooperation with the Chair of Mechanical Process Engineering at the Technical University of Dresden and Topas GmbH, Dresden (Fig. 2). This sensor is based on the optical principle of light extinction. As soon as particles in the plastic melt pass through the laser beam, absorption and scatter effects cause a corresponding change in the signal on the dete...
