EMI/RFI Shielding Formulations

Surround™ EMI/RFI Shielding Formulations

Protects Electronics

Surround is an electrically conductive, long fiber thermoplastic material formulated specifically to work in critical electronic applications such as advanced driver assistance systems (ADAS), medical devices, and wire and cable and electrical connectors. These formulations provide electromagnetic and radio frequency interference (EMI/RFI) shielding at a weight reduction of up to 60% as compared to aluminum, copper and other metals.

福彩3d三天计划两胆码Additional benefits and features of Surround formulations vary depending on the reinforcing additives used, such as nickel-coated carbon fiber and stainless steel fiber. A variety of base resins can be used to create Surround formulations.
