PU Anechoic Chamber Absorbing Material Polyurethane Foam Sound Absorbing Chamber

Polyurethane foam (PU) Anechoic Chamber Absorbing Material

Polyurethane foam (PU) absorbing material is a porous functional material with polyurethane as the base, which is made by introducing absorbing agents (such as carbon materials, magnetic particles) into the foam body. This material is light in weight, flexible and easy to be processed into shapes such as sharp splits. It is a key material for building microwave anechoic chambers and simulating free-space environments, and is widely used in fields such as electromagnetic compatibility testing and stealth technology.
