A new generation of absorbing material using polypropylene as the substrate, with the addition of high-performanceelectromagnetic wave absorbers, flame retardants, and other auxiliaries. After granulation, it is prepared into beadsusing carbon dioxide supercritical foaming technology, and then molded via compression molding. EPP absorbingmaterial is specifically designed for efficient electromagnetic wave absorption and offers outstanding performance. Itcan provide stable absorption effects across a wide frequency band.

Physical Propertes
● Pyramidal shape, black, detachable for easy transportation.
● Water absorption rate is typically low, around 2%-5%. Maintains good performance in humid environments, not easily affected by moisture, suitable for various environmental conditions.
● Can be processed into different shapes and sizes through cuting, hot pressing, and other methods, offering high plasticity to adapt to various customized requirements.
● Installation method: Modular assembly, facilitating anechoic chamber relocation, disassembly, and material replacement.
● Operating temperature: -60°C to 70°C.
Flame Retardant Properties
● The material thickness to wavelength ratio (d/λ) affects reflectivity; greater thickness results in lower reflectivity. Increasing material thickness can effectively improve its absorption performance and reduce electromagnetic wave reflection.
● When d/λ is 0.5, 1, 2, and 6, the normal incidence reflectivity (Rw) can reach -25, -30, -40, and -50 dB respectively.
Technical Specifications
● Operating Frequency Range: 30MHz-110GHz.
Environmental Properties
● Excellent environmental performance, high cleanliness.
● Contains no toxic or harmful substances, complies with international environmental standards, releases no harmful gases or pollutants during use, ensuring no harm
to the environment or human health.
Application Areas
● Scenarios requiring electromagnetic shielding such as communications, radar, military, aerospace, etc. Especially suitable for environments with high-power electromagnetic wave absorption and high reflection loss requirements.
Flame Retardant Properties
● Excellent flame retardant effect, can achieve Flame
● Retardant Grade B2 (GB8624-2012).
