ARCs 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, ARCs 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.Features and Benefits:Absorption of electromagnetic energy from 2GHz to 40GHz Flexible, lightweight and conformable Broadband performance characteristics Standard thicknesses from.125" - 2.0" (3.18mm - 50.8mm) Custom thicknesses up to 6.0" (152.4mm) Low cost EMI solution Integrated ground plane availableControls surface current Environmentally protective surface coatings available Choice of dielectric properties to optimize absorptive performance Easily attached with pressure sensitive adhesive UL94 HB flammability rating (UL file no. E204422) Easily cut, die-cut or flexed to any shape or size
