**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**

## **APPLICATIONS** 

- Eccosorb 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 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 LS to its surface. 

## **Eccosorb® LS** 

## Lossy, Flexible, Foam Microwave Absorber 

## **AVAILABILITY** 

- Standard sheets are 610mm x 610mm (24”x24”). 

- Standard thicknesses are 3.2 mm (1/8”), 6.4 mm (1/4”), 9.5 mm (3/8”), 12.7 mm (1/2”), 19.1 mm (3/4”). 

- All Eccosorb LS types can be delivered in special sizes or customer specified configurations upon request. 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.
