Eccosorb® LS Lossy, Flexible, Foam Microwave Absorber LOSSY, FLEXIBLE FOAM ABSORBER Eccosorb LS is the most widely known, used, and recommended polyurethane foam absorber for both isolation/ insertion loss as well as cavity resonance purpose. Eccosorb LS obtains its microwave properties via impregnation with a carbon black dispersion and is therefore electrically conductive. It is a cost efficient solution for many applications over the thinner rubber absorbers. FEATURES AND BENEFITS MARKETS  Flexible, foam material  High loss, low density  Tuned serie     Commercial Telecom Test Boxes Security and Defense Sensor SPECIFICATIONS TYPICAL PROPERTIES ECCOSORB LS Max.

This includes die-cut and kiss cut parts to reduce installation labor by allowing quick assembly.  Usually Eccosorb LS is supplied with a pressure sensitive adhesive.  Upon special request, Eccosorb LS can be supplied with an anti-dust coating to prevent carbon fallout.  It can also be supplied, upon request, with a coating to prevent moisture uptake in high humidity to moderately wet environments. INSTRUCTIONS FOR USE  For optimal performance, Eccosorb LS should be bonded to a metallic surface.  To obtain a strong bond, the surface should be thoroughly cleaned with a degreasing solvent.  It can be securely bonded to itself or to other materials such as metal, wood and common plastic composites. Our specific Eccostock® foam adhesive is recommended or the selfadhesive version can be used.  The material can be easily cut with a sharp knife, scissors or die. dB Insertion Loss Approximate Insertion Loss at 3 GHz and 45° 60 LS-30 LS-28 LS-26 LS-24 LS-22 LS-20 LS-18 LS-16 LS-14 50 40 30 20 10 0 3.2 USA: +1.866.928.8181 6.4 9.5 12.7 19.1 Thickness (mm) Europe: +49.8031.24600 Asia: +86.755.2714.1166 www.laird.com RFP-DS-LS 070116 Any information furnished by Laird Technologies, Inc. and its agents is believed to be accurate and reliable.
