Conductive foam divider is a composite product that combines the properties of conductive material and foam. It is usually composed of foam substrate (such as polyurethane or polyethylene) and conductive coating (such as carbon black, metal powder, etc.), through a special process will be tightly combined to form a conductive foam material. This material maintains the flexibility of the original foam at the same time, but also has a good electromagnetic shielding effect, can effectively prevent the accumulation of static electricity, and reduce electromagnetic interference.
Features
- excellent conductivity: conductive foam divider surface covered with a thin layer of conductive material, so that the entire material has a good conductivity.
- efficient EMI / RFI shielding performance: for electromagnetic waves have a very good absorption, can effectively block the external electromagnetic fields on the internal circuitry.
- good physical properties: in addition to conductive, the product also inherited the ordinary foam lightweight, flexible, cushioning shock absorption and other characteristics.
- easy processing: can be cut into various shapes and sizes as needed, easy to install and use.
- Strong environmental adaptability: wide temperature range, can work stably in a wide range of temperatures; at the same time, it has a certain degree of corrosion resistance and water resistance.
Applications
- Electronic equipment: used in cell phones, tablet PCs and other portable electronic products for screen edge sealing, can play a role in dustproof and waterproof, but also to enhance the overall electromagnetic compatibility of the equipment. Applied to the inside of the computer chassis, as a filler at the interface, in order to achieve the purpose of isolating the external electromagnetic interference.
- Automotive industry: used for sensor protection in automotive electronic control systems to ensure that signal transmission is not affected by external factors. In-car entertainment systems and navigation equipment around the use of such materials to improve its anti-interference ability.
- communication base station: in the process of communication base station construction, the use of conductive foam divider for isolation between key components, to ensure the safety and reliability of information transmission.
- medical equipment: high-precision medical instruments often contain a large number of sensitive components, the use of conductive foam cutter card can help build a clean and interference-free working environment.
- Other fields: such as aerospace, military equipment and other fields also have a wide range of applications, especially in the need to strictly control the electromagnetic environment is more important.
