LIGHTING vegaform evolution

Product catalog summary

Introduction
Vegaform Evolution is a range of aluminum-based reflector materials designed for applications requiring hollow forming and deep pressing. These materials are pre-anodized and coated with high reflectance PVD layers, ensuring excellent optical performance even after deformation.

Specifications
The product is available in medium to soft temper and can be deformed using specially adapted pressing techniques. It maintains high reflectance and coating adhesion, with a total reflectance of about 95% before deformation. After deformation, reflectance slightly reduces but remains significantly higher than post-anodized materials.

Reflective Performance
Vegaform Evolution retains high reflectivity even after elongation. For example, after a 7.5% deformation, the VFE95100 variant maintains over 90% reflectance. The product is available in various thicknesses and finishes, suitable for different reflector applications.

Mechanical Properties
The product range includes different alloys and tempers, each with specific tensile strength, proof stress, and elongation properties, catering to various forming requirements.

Environmental and Durability Tests
Vegaform Evolution has been tested for temperature resistance, humidity, and salt spray. It shows no reduction in reflectance or visual changes after exposure to high temperatures and humidity. While its salt spray resistance is slightly lower than anodized aluminum, it remains suitable for outdoor use with appropriate IP ratings.

Conclusion
Vegaform Evolution offers a high-performance solution for reflector applications, combining excellent optical properties with durability and adaptability to various forming processes.

Catalog excerpts

vegaform evolution benefit performance of our PVD coated finishes in applications requiring hollow forming and deep pressing. vegaform evolution is a range of medium to soft temper, aluminium based, reflector materials produced from pre-anodized aluminium coated with special high reflectance PVD layers designed to provide high light output even after deep drawing operations. The high reflectance coatings are applied to coil and flat sheet products. vegaform evolution can be deformed using specially softned adapted pressing techniques and the coating technology employed allows the reflector shape...

Environmental tests Temperature resistance Panels of vegaform evolution VFE95100 have been held at a temperature of 250°C for 7 days and no reduction in reflectance values or change in visual appearance was observed. In the case of hard rolled products there would be, of course, a softening of the aluminium after this treating but as vegaform evolution is already produced in a softened condition it is not so affected. Humidity tests In humidity tests, at 100% humidity at 38°C (ISO 6270-1), the evolution products show the same good resistance to deterioration as anodized aluminium. This has been...
