The use of shielding and absorbing materials is becoming increasingly widespread in our modern world. Guided by the actual need of protecting the environment from the dangers of electromagnetic interference (EMI), companies have developed the 3M CN4490 0.875" X 54.5YD shielding and absorbing material. It is 100% polyester woven fabric, featuring both flame retardancy and good electrostatic discharge (ESD) properties. Its application field is mainly used in the automotive, military and aviation sectors, and its working principle is based on the principles of Faraday cage shielding.

The basic function of the Faraday cage is to provide an electrical shield by allowing the formation of an electrical shield that can be used to prevent the unwanted influence of electromagnetic fields. By the action of this electromagnetic shielding material and its electrostatic features, the 3M CN4490 0.875" X 54.5YD shielding and absorbing material is able to absorb the radiation emitted by electrical and electronic equipment and prevent it from affecting the environment. The shielding and absorbing material also offers excellent protection against RF and EMI.

The 3M CN4490 0.875" X 54.5YD shielding and absorbing material works by preventing the electromagnetic energy fields from propagating into the surrounding area by reflecting the radiation on its own surface and redirecting it back towards the source. This electromagnetic shield is capable of protecting nearby spaces and provide a safe environment. Additionally, it also serves the purpose of reducing electric field disturbances and consequently increasing the signal integrity and accuracy of the data being transmitted.

Furthermore, the 3M CN4490 0.875" X 54.5YD shielding and absorbing material also works by dissipating the electric charge that accumulates on its surface. This phenomenon is known as the ‘Faraday cage effect’ where the electric charge accumulates on the material’s surface and gradually dissipates. This effect is important for ensuring that the electric charge does not build up on the surface of the shielded environment and damage the equipment. This material is also effective in eliminating static electricity, reducing radiation and noise, and increasing transmission speed and reliability.

These properties make the 3M CN4490 0.875" X 54.5YD shielding and absorbing material the ideal choice for any application that requires shielding or absorption. It can be used to protect electronic components from toxic or corrosive elements, to ensure the safety of people operating machinery or performing experiments where electric or electromagnetic fields are present, and to safeguard sensitive components from EMI and RF. Its ability to reduce and absorb electromagnetic radiation can significantly improve the performance of many systems and equipment.

The 3M CN4490 0.875" X 54.5YD shielding and absorbing material is durable and highly effective in providing a safe and shielded environment. The material is relatively easy to install and can be used for a variety of applications across various industries. It is able to protect from the dangers of both EMI and RF, and its use can help improve the accuracy and signal quality of electronic systems and equipment.
