ECCOSORB AN-77

ECCOSORB® AN-77 is a lightweight, flexible polyurethane foam sheet broadband microwave absorber designed for electromagnetic energy absorption and reflection reduction in RF and microwave environments. As part of the ECCOSORB AN family, AN-77 is engineered to provide greater than 17 dB reflectivity reduction above 1.2 GHz when mounted on a metal surface. Its carbon-loaded multilayer construction combines broadband absorption performance with low weight, making it suitable for antenna isolation, anechoic chamber treatments, radar testing, and test chamber lining applications. The material is RoHS and REACH compliant and can be supplied in standard sheets or custom configurations to accommodate specific installation requirements.

Key features

• Broadband microwave absorption: Designed to achieve greater than 17 dB reflectivity reduction above 1.2 GHz when mounted on a metal surface.
• Lightweight flexible foam construction: Polyurethane foam design allows easier handling and integration into RF test and antenna systems.
• Carbon-loaded multilayer structure: Supports effective free-space absorption for reflection control and antenna isolation applications.

Applications / Suitable for

• RF and microwave test chamber lining
• Reducing crosstalk between adjacent antennas
• Antenna shrouding to improve radiation pattern control and reduce backlobes
• Radar cross-section (RCS) measurement shadowing applications
• Shadowing posts and supports in anechoic chambers
• Absorbing blankets for radar system testing
• Antenna and component isolation applications
