HYFRAL APM is a range of high performances broadband electromagnetic absorbers. Each absorber consists of a single block of high tech polyurethane foam, pyramidal-shaped and impregnated carbon-based aqueous solution. HYFRAL APM are suitable for broadband applications, and are used to line semi-anechoic chambers for EMC, Radar Cross Section, compact ranges, antenna pattern, telecom, military applications (see "Compact EMC test chamber").
SIEPEL R&D engineers work with state-of-the-art electromagnetic numerical simulation software, in order to constantly optimise both shape and impregnation agents of the absorbers, over broad frequency ranges.
SIEPEL is the only manufacturer in the world to propose plastic paint coating for pyramidal absorbers. This special painting treatment has been developed to provide good fixing of the carbon and very good ageing process. Moreover, plastic paint is partly responsible for excellent shape memory features and fire retardant properties of APM absorbers. This plastic paint can be proposed in several incomparable colours : please contact us for your company's name or logo printing in your chamber !
