SRCH Microwave Absorber Material, PolyIron

Unlike common Salisbury shields or gaskets, PolyIron magram absorber works to attenuate EMI by absorbing it, not by reflecting it. This is particularly important in small enclosures, where high frequencies cause cavity resonance—something shields do not really address. In today’s densely packed microwave devices where space is at a premium, PolyIron has significant advantages, because typically 0.2mm to 4.5mm thickness of PolyIron is all that is required.

PolyIron consists of a 5 to 1 pure iron oxide powder, mixed with various catalysts to form a flexible material that is non-conductive, so you may use it effectively even in the most confined of enclosures, such as a handset, for small spaces surrounding vehicle avoidance radar, or to reduce antenna sidelobe interference.
