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 40% as compared to aluminum, copper, and other metals. They also can eliminate additional painting steps to an application in need of shielding protection.
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 to either concentrate (intended to let down at the press) or direct-to-mold fiber loadings.
Lightweighting
Impact
- Provides integrated EMI/RFI shielding on par with metals
- Eliminates need for secondary operations
- Design freedom of injection molding, including thinner walls
- Lighter weight and easier to process than aluminum or copper
- Durable and non-corrosive
