Lossy Foam Block Absorber (EHP-LFBCL)

Broadband Block Absorber for Uncertain Environments

Extra High Performance Lossy Foam Block Combustion Limiting (EHP-LFBCL) broadband absorber is part of a line of combustion limiting polyurethane absorber made from urethane foam impregnated with a dielectrically matched conductive carbon, and cut into blocks to suit the application. LFB absorber effectively reduces reflections between 30 MHz to 100 GHz. ETS‑Lindgren guarantees its EHP series absorber to absorb 1/2 W/in² without material damage.

Developments in chemical engineering have allowed ETS‑Lindgren to utilize a non-hygroscopic, moisture-resistant substrate. ETS‑Lindgren absorber experiences a mass increase of less than 3% when subjected to 95% relative humidity at 100 degrees Fahrenheit for at least 240 hours.

Key Advantages:

• Reduces Reflections Between 30 MHz and 100 GHz
• Absorbs 1/2 W/in² 
• Customizable for Thickness and Dimensions for Any Application
