Rohacell® HF is a closed-cell rigid foam with extremely low dielectric constants and particularly favourable 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. It is also used in Radomes and mammography plates
Rohacell® WF is a closed-cell rigid foam which has been designed for use primarily in aerospace applications. It satisfies the usual industry requirements and also the MIL and CMS Rohacell® WF rigid foam can be processed at pressures of up to 0.7 MPa and temperatures of up to 130°C. It is therefore highly suited for autoclave prepreg processing and all typical resin infusion after heat treatment, Rohacell® WF can even tolerate curing temperatures of 180°C at a pressure of 0.7 MPa. Rohacell® WF is easy to shape with CNC routing equipment.
Rohacell® RIST is a closed-cell rigid foam It has been specially developed for use as a structural core in connection with vacuum infusion processes. Its mechanical and thermo-mechanical properties are similar to those of RohacellL® WF. Its cell size, however, represents an optimal compromise between low resin uptake, about 50% less than for the WF grade and satisfactory bonding of the facings to the foam core. Its optimized cell structure makes Rohacell® RIST particularly suitable for vacuum infusion and RTM processes, where it can be used at temperatures of 130°C and up to a pressure of 0.7 MPa. Heat treated Rohacell® RIST-HT allows safe and stable processing at a temperature of 180°C with pressures of up to 0.7 MPa. Rohacell® RIST can easy be shaped by CNC digital machining.
