RF Absorber
EPP Absorber

Specification

  • Flammability: DIN 4102 Class B2, B1 class option available

  • Little carbon dust, excellent moisture resistance

  • Base size: 500*500mm, 600*600mm

Details

EMCPIONEER EPP absorbers are made from expanded polypropylene (EPP) beads with carbon powder evenly distributed through the absorber cone. Furthermore, the minimal shedding of carbon particles allows these materials to be used in environments containing precision electronic equipment or in cleanrooms, thereby reducing the risk of equipment failure caused by dust contamination.

The pyramidal structure reduces unwanted reflections in EMC test chambers, anechoic and semi-anechoic chambers, and antenna measurement facilities.
