ROHACELL® HF: Negligible Absorption in the High Frequency Range

With its extremely low dielectric constants and particularly favorable transmission properties in the high frequency region, ROHACELL^® HF has been specially designed for antenna applications.

Applications range from miniature antennas in cell phones to large fixed ship-based and stationary antenna structures. Other advantages of ROHACELL^® HF in such applications are its extremely fine cell structure that ensures minimal resin uptake, and problem-free compatibility with metallic facing materials due to the absence of corrosive effects.
ROHACELL^® HF is also used in radomes and mammography plates.

Fine-cell materials can be processed by hand lay-up, prepreg, or vacuum infusion techniques at pressures up to 0.3 MPa and temperatures up to 130°C.
