RF WALKWAY ABSORBER

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

DMC 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.

  • Frequency range 500MHz to 40GHz
  • Typical reflectivity as high as -45dB
  • Max load capacity 302 kg/m2
  • Power handling capacity 4.8kW/m2, 1353 V/m CW Radiated field strength
  • Fire Retardant per NRL-8093 1,2,3, UL 94:2013, HBF and DIN 4102 and Class B2
  • Continuous working temperature up-to 120°C
  • Clean Room suitable per ISO 14644 Class5
  • Water Resistant per GB/T 4208-2017
  • RoHS and REACH Compliant
  • Zero Carbon dust
