High Loss UHF and Microwave Magnetic Absorber
PPG C-RAM® FF-2 is a thin, flexible, ferrite filled silicone rubber sheet stock, which has high magnetic loss at UHF frequencies up to X-band.
PPG C-RAM FF-2 is electrically non-conductive and it has a high dielectric strength.
PPG C-RAM FF-2 has a high magnetic loss tangent from about 500 MHz to 10GHz. In the UHF range, PPG C-RAM FDSS will perform in an equal fashion; it has different magnetic filler which exhibits high loss tangents at UHF frequencies, but PPG C-RAM FF-2 should be used if absorption above 2 GHz is also desired.

Standard sheet size is 12 in. x 12 in. (305 mm x 305 mm). PPG C-RAM® FF-2 is available in thicknesses ranging from 0.010 in. up to 0.125 in.
PPG C-RAM FF-2 can be supplied in other sizes, thickness or per customer specified configurations upon request.
PPG C-RAM FF-2 can also be supplied with a peel-and-stick pressure sensitive adhesive backing, order as FF-2/PPGA.
As a standard, the PPG C-RAM FF-2 base material is silicone, but it can also be supplied in a urethane base version.
