ROHACELL® in antennas and electronics 

Are you looking for a material for dielectric applications that combines the RF transparency of air with unrivalled processing performance at up to 190 °C (374 °F) and superior mechanical properties? Look no further: ROHACELL® rigid foam is doing the trick! 

Because ROHACELL® offers such a high permittivity, the material is ideally suited for substrates or dielectric spacers in antennas. ROHACELL® HF is designed for direct contact with metallic antenna panels. The ultrafine cell structure allows for high precision shaping of even the most delicate structures and makes it an ideal spacer for mobile and stationary antenna technology..

Its low loss properties also make ROHACELL® foam the first choice for radome sandwich cores. The high strength and stiffness contribute significantly to protecting the most sensitive antenna designs while maintaining transparency for electromagnetic waves, enabling maximum efficiency in antenna operation.  By applying an efficient thermoforming process, the material can be formed into complex and even double-curved shapes. 

Real 5G. ROHACELL® is a clear choice

We sat down with Tobias Björnhov, CEO of Corebon (Malmö, Sweden) to talk about the reason they use Evonik’s ROHACELL® foam, and where the future of 5G communication is going.
