High Performance RF and Microwave Walkway Absorber – Expanded Polypropylene (EPP) and Foam Polyurethane (PU)

High Performance RF and Microwave Walkway Absorber

DMC RF walkway absorber structure is topped with a higher density Polypropylene laminate. PP-WW series offer excellent load bearing and wear characteristics. The material’s ability to withstand higher loads than most walkway materials is due to the construction technique. The standard Walkway absorbers are available in 600mmx600mm or 600mmx1200mm footprint dimensions. Custom sizes and shapes can be provided. The walkway absorber is taller than standard absorber. We generally recommend using walkways one size smaller than surrounding absorbers. Typical reflectivity data can be provided upon request.
