Key Features

  • Compatible with Anechoic Chamber Reflection Requirements
  • Smooth Walking Surface Impervious to Water and Dirt
  • Supports up to 90.7 kg per .3 meters (200 lb ft2)

ETS-Lindgren's Extra High Performance Walkway Absorber is a special absorbent material that is compatible with anechoic chamber reflection requirements, yet provides a walking surface for personnel.

Low-density rigid polystyrene foam is used to encapsulate a standard pyramidal or wedge absorber. A thin sheet of semi-rigid polyvinyl chloride foam is adhered to the top to provide a walking surface, which is smooth and impervious to water, and dirt. The Walkway Absorber fabricated in this manner will support up to 90.7 kg per .3 meter (200 pounds per ft2) and is durable and easily maintained.

Reflections will occur at any foam surface, the magnitude of the reflection being dependent on the density of the material. The ETS-Lindgren walkway absorber utilizes the lowest possible foam density consie resin film, the highest temperature polymer available.
