PolyOne, based in Cleveland, Ohio, is rebranding its ElectriPlast material technology as Surround EMI/RFI shielding formulations.

This portfolio of conductive long fibre thermoplastic materials shields sensitive electronics from both electromagnetic interference (EMI) and radio frequency interference (RFI). Surround weighs up to 60% less than aluminium or copper, and brings increased design freedom compared to metal.

Surround long-fibre material is well suited to housings for advanced driver assistance systems (ADAS) because of its capability to replace metal in shielding applications. As car makers continue to add ADAS functionality to vehicles, more electronic control units (ECUs), cameras and sensors are needed to make the systems function properly. In addition to minimising cross talk between electronic components, Surround material is lighter weight and easier to process than traditional materials such as aluminium or copper. Injection moulding also permits more complex shapes and fewer design constraints, all without compromising on dimensional stability of the component during use.

With its integrated EMI/RFI shielding capabilities, Surround material adds depth to PolyOne’s existing electrically conductive and shielding material line-up. It is also well positioned for additional shielding applications, including camera housings and connectors beyond the automotive market.
