Radar Absorbing material description
Main features: large thickness, good flexibility, high absorption rate, good stability (-40℃-120℃)
It has good absorption characteristics for both specular waves and surface waves.
Main applications: communication and radar system clutter suppression, anti-electromagnetic interference, microwave anechoic chamber, etc.
The flat-plate Radar Absorbing Foam sheet absorbing material is a solid foam absorber, which has good broadband absorbing performance under the conditions of vertical incidence and oblique incidence of electromagnetic waves and is widely used in various microwaves anechoic chambers.
Using a computer profiling cutting machine for polyurethane foam pyramid cutting, the appearance structure is beautiful, the size is accurate, there is no dust shedding, no moisture absorption, and discoloration.
The product specifications are complete to meet the requirements of different types of darkrooms and shielding boxes, and there are special materials suitable for corners, vents, lighting, and other special parts to meet special use requirements.
The flame retardant performance meets the requirements of the national B2 material standard, the oxygen index ≥28%, and meets the requirements of the NRL 8093 test standard.
Specially designed and manufactured production equipment and strict production process control are used to ensure the consistency, stability, and reliability of product performance, and to ensure the performance requirements of the overall microwave anechoic chamber.
