Sponge absorbing material, microwave darkroom shielding room, electromagnetic shielding material, detailed answer

Sponge absorbing materialIntroduction:

Main features: large thickness, good flexibility, high absorption rate, and good stability (-50 ℃ -150 ℃)

It has good absorption characteristics for both mirror waves and surface waves.

Main applications: clutter suppression in communication and radar systems, anti electromagnetic interference, microwave anechoic chambers, etc. PXB solid cone angle

Absorbing materials are a type of absorbing material that has been used for a long time and has a wide range of applications. They are widely used in the construction of radio waves

Darkrooms, microwave darkrooms, dark boxes, absorbing screens, and absorbing barriers are used to cover reflective objects in the testing environment,

Reduce background noise, clutter interference, and improve testing accuracy.

Radio anechoic chamber (anechoic chamber, microwave anechoic chamber, EMC electromagnetic compatibility anechoic chamber, etc.); Absorbing screens and walls, etc;

Covering the reflective objects in the testing environment, reducing background noise and clutter interference, and improving testing accuracy.

Indoor use, not suitable for outdoor use

    Flat plate absorbing materialIt is a solid foam absorber. When electromagnetic waves are vertically and obliquely incident

In all cases, it has excellent broadband absorption performance and is widely used in various microwave darkrooms.

The computer profiling cutter is used to cut the polyurethane foam corner cone, which has beautiful appearance and size

Accurate, no dust shedding, no moisture absorption or discoloration phenomenon. The product specifications are complete and meet the needs of different types of darkrooms

The use of shielding boxes requires special materials suitable for corners, ventilation openings, lighting, and other special areas

Special usage requirements.

The flame retardant performance meets the requirements of B2 level material standards, with an oxygen index of ≥ 28%, and meets the requirements of NRL 8093 test standards.

By using specially designed and manufactured production equipment and strict production process control, we ensure the consistency, stability, and reliability of product performance, and guarantee the overall performance requirements of the darkroom.
