Bright-dg leading manufacturer of Electromagnetic Shield and silicone products. Our products are widely used in mobile phones, laptops, pcs and so on. We are looking for global agents. An electromagnetic shield is a device or material that is used to block or reduce the passage of electromagnetic waves. Electromagnetic waves are a type of energy that includes radio waves, microwaves, X-rays, and gamma rays. They can be harmful to electronic equipment and can also cause interference with radio and other communication systems. Electromagnetic shields are often made of metal, such as copper or aluminum, which can reflect or absorb electromagnetic waves. They can also be made of other materials such as conductive rubber or plastic, which can absorb electromagnetic waves. Electromagnetic shields are used in a wide range of applications, including electronic equipment, automobiles, aircraft, and buildings. They can be used to protect electronic equipment from interference, to prevent the transmission of radio signals from inside a building, and to protect people from exposure to harmful electromagnetic radiation. There are different types of electromagnetic shields, such as Faraday cages, which are used to completely enclose a piece of equipment and shield it from all external electromagnetic fields. Another type is the electromagnetic gasket, which is used to seal the interface between two parts of an electronic device or an enclosure to prevent electromagnetic interference from entering or leaving.
