Pyramidal absorber for medium power applications

PPG C-RAM^® SFC-MP is a series of high performance broadbanded RF absorbers made from specially treated low density polyurethane foam.

Using a steep pyramid design which provides an impedance gradient, PPG C-RAM SFC-MP provides premium performance in anechoic chambers at both normal and off-normal incidence angles.

These products meet all of the fire retardancy requirements:
• NRL Specification 8093 tests 1, 2, and 3
• MS-8-21 tests 1, 2, and 3
• T.I. drawing 2693066
• ASTM E-84-97a, Class A
• UL94 rated HF-1

PPG C-RAM SFC-MP is a series of very high-performance pyramidal absorbers capable of handling medium-power densities. It is an open cell, porous material, and is used in anechoic chambers or test environments where RF power densities will be higher than the standard PPG C-RAM SFC can withstand.
