Radio frequency interference (RFI) and electromagnetic interference (EMI) are forms of electromagnetic energy that can interfere with both electronic and electrical systems. These types of interference can cause the destruction of electrical equipment, interference with other wireless equipment, and data transmission errors. In order to prevent this interference, shielding and absorbing materials can be used.

One of the most common types of shielding and absorbing materials are 21164155. This type of material is a polyurethane foam that has a shielding effect against both RFI and EMI. It is able to absorb and block the radiation from both types of interference. This material is typically used in applications such as shielding electrical cabinets, power switches, and industrial control systems.

The working principle of this type of material is to absorb and block the radiation from the interference sources. The polyurethane absorbs the energy from the radiation and effectively blocks it from reaching the equipment. This material also has the ability to reflect some of the energy, reducing the amount of radiation that gets through to the equipment.

Another type of shielding and absorbing materials are corkboard. This type of material is also effective at blocking both RFI and EMI, as well as reflecting some of the energy. Corkboard is typically used in applications such as shielding control panels, power outlets, computers, and telecommunications systems.

The working principle of this type of material is similar to 21164155. It absorbs and reflects the radiation, preventing it from reaching the equipment. Additionally, corkboard is able to dissipate some of the energy, further preventing it from reaching sensitive equipment.

In addition to shielding and absorbing materials, there are also other types of materials that can be used to reduce the amount of interference. Shielded cables and shielding fabrics are two such materials. These materials are typically used to further protect sensitive equipment against RF and EMI interference.

Overall, 21164155 and corkboard are two of the most common types of shielding and absorbing materials used to reduce the interference caused by RFI and EMI. They work by absorbing and blocking the radiation and dissipating some of the energy, thus preventing it from reaching the electronics or electrical equipment. Additionally, these materials can also be used in conjunction with other types of materials, such as shielded cables and shielding fabrics, to further protect the equipment against interference.
