ECCOSORB(R) LS Lossy, Flexible, Foam Microwave Absorber Material Characteristics * * * * * * * ECCOSORB(R) LS is the most widely known, used, and recommended urethane foam sheet product. High loss, low density, and very flexible ECCOSORB(R) LS obtains it's microwave properties via a carbon loading system and is therefore, electrically conductive Very low cost solution for many applications over the thinner, more expensive rubber absorbers Not weatherproof but can be supplied with a weather resistant CERSEAL coating, see Availability below If UL-94-HF-1 fire retardancy is a requirement, see ECCOSORB(R) QR-13AF Can be easily cut with a knife, scissors, or die Instructions for Use * * * Being electrically conductive ECCOSORB(R) LS could cause a short in some microwave circuits, but only if the material comes in contact with components, see PEF film under Availability For high loss applications, ECCOSORB(R) LS-28 and LS-30 are recommended ECCOSORB(R) LS can be securely bonded to itself or to other materials such as metal, wood, and common plastic composites. The recommended adhesive is ECCOSTOCK(R) 13-111-NF if not ordered from the factory with a PSA. Typical Properties Applications * * * ECCOSORB(R) LS is used to lower cavity Q's in RF amplifiers, oscillators, cabinets containing microwave devices, computer housings, LNB's, and isolation of antennas by insertion loss ECCOSORB(R) LS is also used to reduce surface currents on radiating elements and outer ground-plane type surfaces. Reflectivity of an object (metal or otherwise) can be reduced somewhat by applying one or more layers of ECCOSORB(R) LS to its surface Frequency Range 1 to 26 GHz Service Temperature, F (C) -94 to 200 (-70 to 93) Color Black ' 3 - 20 ' 1.0 tan m 0.0 Fire Retardancy UL 94 HBF Availability * * * * * * * Standard sheets are 24" x 24" (61 cm x 61 cm) Standard thicknesses are 1/8" (0.3cm), 1/4" (0.6cm), 3/8" (0.9cm), 1/2" (1.3cm) & 3/4" (1.8cm) Upon special request, ECCOSORB(R) LS can be supplied with an anti-dust coating UMSEAL (UM), to prevent carbon fallout ECCOSORB(R) LS can be supplied with a CERSEAL coating to prevent moisture uptake in high humidity to moderately wet environments upon special request For applications requiring ECCOSORB(R) LS to be in close contact with electrical components, a PEF film is available on request to prevent electrical shorts ECCOSORB(R) LS can also be supplied with a Pressure Sensitive Adhesive (PSA).
