Product Description
Eccosorb LS-30/SS3 is a flexible polyurethane foam microwave absorber grade with an SS3 pressure-sensitive adhesive configuration. Carbon-black impregnation gives the foam its lossy, electrically conductive behavior for isolation, insertion loss, and cavity-resonance control above 1 GHz. Grade-level data for LS-30 include attenuation of 24 dB/cm at 3 GHz and 46 dB/cm at 10 GHz, with a maximum service temperature of 90 deg C. Multiple exact LS-30/SS3 thickness configurations are available for bonding to metal surfaces in RF amplifiers, oscillators, microwave cabinets, antenna-isolation structures, and other assemblies where reflection or surface-current reduction is needed.
Key features
- High-loss LS-30 grade: Typical attenuation is 24 dB/cm at 3 GHz and 46 dB/cm at 10 GHz.
- Flexible conductive foam: Carbon-black-impregnated polyurethane supports absorber placement on RF structures.
- SS3 adhesive configuration: Multiple exact LS-30/SS3 thickness configurations include pressure-sensitive adhesive.
Applications
RF amplifier and oscillator cavities, microwave-device cabinets, antenna isolation, reflection reduction, and surface-current control.
