ROHACELL HF Performance Foams

ROHACELL HF is a closed-cell rigid foam based on polymethacrylimide (PMI) chemistry that is completely free of CFC’s. With its extremely low dielectric constants and particularly favorable transmission properties at high frequencies, ROHACELL HF is ideal for use in antenna applications.

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
