Surround™ EMI/RFI Shielding Formulations

Formulations combining the EMI/RFI shielding properties of metal with the lightweighting and processing ease of a plastic

SurroundTM 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.

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. 


  • Integrated EMI/RFI shielding, eliminating the need for secondary operations like painting or vacuum metallization
  • Injection moldable, long fiber technology enables increased design freedom and thinner wall housings as compared to aluminum, without compromising on dimensional stability 
  • Surface resistivity targeted at 100 to 102 ohms/sq
  • Promotes device and device housing miniaturization
  • Lighter weight and easier to process than aluminum or copper
  • Durable and non-corrosive
