negligible absorption in the high frequency range
ROHACELL® HF
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.
