PU Foam Microwave Pyramidal Absorber

Pyramidal Microwave absorber is carbon and retardant chemicals loaded polystyrene absorber,it`s designed to give excellent performance at broadband. Features:Rigid structure so that it does not sag under it`s own weight even higher than 2metres longExcellent performance from 30MHz to 18GHz and does not suffer the compromises of the ferrite + pyramidal hybrid systemBe easily mounted using kits, no glueFire retardant to UL94 HBF,DIN4102-B2,NRL8093Ⅰ Ⅱ ⅢRoHS and REACH compliantZero shedding(clean room class ISO14644-1 class 4)Longer service life expectancy(20years+) JA microwave pyramidal absorber aligned light blue quadrangular pyramid, possessing goodfireproof performance which fulfills American NRL Report 8093.Servicetemperature:-50 ℃~70 ℃. It is of good vertical incidence . oblique incidence . scattering and isolated decay performances at thewideband range. It is mainly used for subject material of anechoic chambers.
