The WX-A series of Waveguide Absorbers have been specifically designed with high permeability, temperature and corrosion resistance. They operate from 100 MHz to 18 GHz and are available in sheets with a thickness of 0.005 inches to 1 mm. The sheets provide superior EMI absorption by combining proprietary, high-performance magnetic materials into a flexible, resilient elastomer. By precisely blending refined fillers in exacting ratios with polymer substrate materials, they have created a thin, flexible EMI absorbing sheet that will attenuate from 100 MHz to 18 GHz. The WX-A series is a Halogen free product and passes the ASTM salt fog test.
