The mechanical and optical properties of the PC and PMMA materials already cover a wide range of applications. However, we also offer specially developed blends so you can use our profiles and tubes in other fields of application too. By precisely targeting different material properties, we are able to achieve the optical, mechanical and hygienic characteristics required for specific applications.
The use of an opal or diffuse material can be a problem when using LEDs (Light-emitting diodes). In lighting technology, LED spots do not appear completely bright at a single point. A homogeneous light appearance is therefore not achieved with these material mixtures.
We have therefore developed our own PMMA and PC LED blend especially for this application.
Our translucent material has both high light scattering (deflection of light waves at the material surface) and high transmission (transmission of light waves). The optimum balance between transmission and diffusion positively influences the efficiency (luminous efficacy) of your luminaire. In particular, the choice of material can influence whether or to what extent the individual LED spots can still be seen through the cover.
All listed measurement results were determined in an independent test laboratory in accordance with the valid technical and scientific standards (including DIN EN 13032-1 and -4).
A diffuse tube or profile provides a qualitative solution for distributing and directing light.
Within the material, the incident light beam from the light source is scattered homogeneously via volume scattering. This does not, however, affect the excellent light transmission of the material. The material appears milky here.
Further glare control of the light source can be achieved using an opal material. This causes a reduction in the luminance (brightness level). The visual perception of the material colour is perceived as white.
One of the countless applications of our tubes is in the clinical environment, for example as a sleeve for pneumatic tube systems. Hospitals use these systems to send blood units from the treatment room to the in-house laboratories as quickly as possible. Our special blend of materials prevents the formation of germs on the plastic surface, so our tubes offer maximum hygiene protection. The antibacterial material used for this purpose provides permanent antibacterial protection through silver ions embedded in a plastic matrix. Tests by an independent laboratory show that a reduction of E. Coli by 99.9% (3.0 Log 10) and MRSA germs by 99.98% (>3.72 Log 10). The test conditions are based on ISO 22169, over a period of 24 hours (35 °C, RH > 95%).
Increasing vandalism in public facilities as well as mechanically demanding applications often make the use of impact resistant materials necessary. With our material blends, we can modify the PMMA in such a way that the impact strength is increased. This reduces expensive repair and maintenance costs. As the illustration shows, our materials enable an increase in (Charpy) impact resistance of up to 400 % compared to a non-impact resistant PMMA type.
