Foam Absorbers

Foam AbsorbersARC’s family of low-density, high-loss flexible EMI absorbers are designed to solve a wide range of interference control problems easily, quickly and cost-effectively. Using proven formulas, ARC Technologies combines refined carbon powders with binding agents. The absorbent mixture is then integrated into an open cell, polyurethane foam structure.These precisely controlled, carbon loaded foam absorbers offer excellent suppression of unwanted electromagnetic signals for a variety of applications including telecommunications, high-speed computers, wireless technologies and microwave systems.By varying the thickness and loading levels of these uniformly loaded foam sheets, ARC’s Foam absorbers can be frequency-tuned for a specific application. Various types are available, see the Quicklinks menubar at the left side of this page.
