High power handling microporous pyramid absorbers

High power handling microporous pyramid absorbers 3690

Microporous pyramid absorbers can support inside and outside ventilation circulation

High power handling microporous pyramid absorbers can support inside and outside ventilation circulation, which would further improve the power handling capacity of such absorbers; it is mainly applied in high power shield cabinet, ventilation vents of anechoic chambers, and etc.

Characteristics

Good flame retardant characteristics, it won’t burn when it encounters fire, it has oxygen index ≥ 60% and flame retardant B1 level.
Good power handling property, power handling under forced air cooling (continuous wave) can be up to 8-10kW/m2.
It uses keel mounting method, without any adhesive.
