Flexible, foam sheet-like, wideband electromagnetic wave absorber
The "AN" electromagnetic wave absorber is a lightweight, flexible, wideband, open-cell structure foam polyurethane absorber. It is a multilayered polyurethane sheet impregnated with carbon, with a frequency range from 600 MHz to 40 GHz. The reflection coefficient is -20 dB compared to a metal plate in the specified frequency band at normal incidence angles, and it has antibacterial properties according to MIL-STD-810E. It can be easily cut with a band saw, scissors, or a knife. 【Typical Characteristics】 ○ Front (incident surface) color: White ○ Maximum operating temperature: 120 ℃ ○ Power handling characteristics: 0.15 W/cm² ○ Thermal conductivity: 6.8x10^-5 cal - cm/ sec - cm² - ℃ ○ Flame retardancy: UL 94 HBF For more details, please contact us or download the catalog.

basic information
【Environmental Resistance Characteristics】 ○ It is not water-resistant, and normal properties cannot be obtained when wet. → However, since the impregnated carbon does not leach out even when wet, it will function normally after drying. ○ There is also a special coating agent, CERSEAL, for moisture prevention in high humidity to normal humidity environments. ○ For applications requiring waterproofing, AN covered with ANW or CERSEAL is recommended. 【Dimensions and Types】 ○ Standard dimensions are 61cm x 61cm. ○ Thickness varies depending on the lower frequency of the desired operating frequency band. ○ Non-standard dimensions, specific shapes, diagonal cuts, and pre-installed metal parts are available. ○ Custom products, such as three-dimensional curved shapes wrapped around a core, are also possible. ● For more details, please contact us or download the catalog.
