High-loss, low density, flexible, carbon loaded foam sheets

Eccosorb LS is a series of light-weight, flexible, dielectrically loaded, polyurethane foam materials.  These foams, black in color, achieve their lossy behavior using a conductive carbon loading system.  Eccosorb LS is not weatherproof, but can be supplied with a special coating for outdoor use or where the absorber may come in contact with fuel, lubricants, or hydraulic fluids. Ecoosorb LS can be easily cut with a knife and held in place with a Pressure Sensitive Adhesive (PSA) or it can be attached with our sprayable glue, Eccostock 13-111.

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.
