ECCOSORB® LS is a series of light-weight, flexible, dielectrically loaded, polyurethane foam materials. These foams, black in color and UL 94 HBF fire retardant rated, achieve their lossy behavior using a conductive carbon loading system. ECCOSORB® LS is not weatherproof, but can be supplied with a special coating called CERSEAL for outdoor use or where the absorber may come in contact with fuel, lubricants, or hydraulic fluids. ECCOSORB LS can be easily cut with a knife and held in place with a Pressure Sensitive Adhesive (PSA) or attached with a liquid based contact cement called ECCOSTOCK® 13-211-NF.
ECCOSORB® LS is available in a wide range of dielectric properties that are best characterized by their insertion loss. They are also available in a wide range of thicknesses to optimize insertion loss properties where isolation is necessary.
ECCOSORB® LS is used to absorb electromagnetic energy in a variety of applications. It can be used to line the interior of a cavity to lower its Q in RF amplifiers, oscillators, cabinets containing microwave devices, computer housings, or LNB’s. It can also be used for the isolation of antennas by insertion loss. Reflectivity of an object (metal or otherwise) can also be reduced to a small degree by applying one or more layers of ECCOSORB® LS to its surface.
