Eccosorb® SLJ Dual-band flexible rubber sheet absorber DUAL-BAND FLEXIBLE RUBBER SHEET ABSORBER Eccosorb SLJ is a flexible nitrile rubber-based flat absorber and is designed to have minimum reflection at 2 frequency bands i.e. X- and Ku bands. Between these 2 resonant frequencies, reflectivity remains typically below -10dB.The nitrile matrix is a very durable material. It has good outdoor weathering characteristics, good resistance to moisture and hydraulic fluids and has proven excellent performance in naval applications. Water and salt water immersion tests showed after 1 month immersion a weight increase of only 0.5 - 0.7 %. No influence on reflectivity was noticed. FEATURES AND BENEFITS

APPLICATIONS
- Eccosorb SLJ is suited for applications requiring reflectivity reduction at several frequencies in harsh environments, particularly on objects with contoured shapes.
- Typically used on masts of ships, wall’s, etc. to reduce reflections and echoes to nearby antennas or attached to vehicles to reduce overall radar signature. AVAILABILITY
- Eccosorb SLJ is available as flat rubber sheets of 600 x 600 x 6.7 mm. Americas: +1.866.928.8181 Asia: +86.755.2714.1166 www.lairdtech.com

INSTRUCTIONS FOR USE
- The design of SLJ requires that its back surface is in intimate contact with a conductive surface.
- If this is not the case, one must first bond a conductive layer, such as aluminum foil, to the surface of the substrate or the back surface of the absorber.
- To obtain a strong bond of the absorber to the object, the metallic surface should first be thoroughly cleaned with a degreasing solvent.
- Bonding can be done with a suitable adhesive for nitrile rubber such as acrylic based adhesives. Typical reflectivity of ECCOSORB SLJ -40 -35 -30 -25 -20 -15 -10 2 4 6 8 10 12 14 16 18 Frequency in GHz Reflectivity in dB ECCOSORB SLJ
