Product Description
RF absorber foams are a type of foam that is used to absorb radio frequency (RF) energy, thus reducing electromagnetic interference (EMI) in electronic devices. These foams have a number of unique properties that make them ideal for use in a wide range of applications.
One of the key properties of RF absorber foams is their ability to absorb RF energy over a broad range of frequencies. This is due to their high loss tangent, which means they are able to convert RF energy into heat very efficiently. This property is particularly important in applications where a wide range of frequencies need to be absorbed, such as in communication systems and radar equipment.
RF absorber foams also offer excellent thermal and mechanical properties. They are able to withstand high temperatures and are resistant to moisture, making them ideal for use in harsh environments. They are also lightweight and flexible, which makes them easy to integrate into electronic devices and communication systems.
