EMI Shielding Compounds for Auto Radar and Sensing Components

Lighter weight materials can replace metal or conductive-coated plastic housings.

Global custom engineered thermoplastics compounder RTP Company has developed EMI shielding compounds that it says are ideal for replacing metal or conductive coated plastic housings in automotive sensing systems.

“The automotive industry is putting more emphasis on reducing mass in order to meet fuel efficiency and emissions regulations,” said Neil Hardwick, marketing manager for conductive products at RTP. “RTP Company’s EMI shielding compounds are an ideal solution for engineers who need to replace metal components with lighter-weight materials that are simple and economical to produce without sacrificing critical EMI shielding performance.”

The compounds can be “tuned” to provide the precise range of EMI protection required for individual automotive systems. Thermal management properties can also be combined with EMI protection in a single ready-to-mold compound, which is advantageous because, like metal, it can be used in a dual role as an EMI shield and a heat sink.

RTP can also incorporate other performance enhancements during compounding, such as EMI absorbers, flame retardants and structural reinforcement.

EMI shielding and other properties can be incorporated into a wide range of resin systems including popular nylons (PA), polybutylene terephthalate (PBT), polycarbonate (PC), or polyetherimide (PEI).
