Thermoplastics compounder RTP Company has developed new EMI shielding compounds ideal for replacing metal or conductive coated plastic housings in automotive sensing systems.
Automotive radar and sensing systems designed to maintain vehicle safety and reliability require EMI protection to eliminate “noise” that could interfere with signal processing, the company says. As the automotive industry continues to incorporate more electronic safety systems into vehicles, these EMI shielding materials are required to be lighter in weight and provide greater design flexibility.
“The automotive industry is putting more emphasis on reducing mass in order to meet fuel efficiency and emissions regulations,” Neil Hardwick, marketing manager for conductive products at RTP company, said. “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 new EMI compounds from RTP Company 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 to provide both an EMI shield and heat sink. Other performance enhancements such as EMI absorbers, flame retardants and structural reinforcement can also be incorporated during compounding.
