Parker Chomerics look to protect advanced automotive electronics from EMI
Published: 12 February 2020 - Christian Lynn
Chomerics Europe has launched the Premier PBT-250FR for EMI shielding in automotive applications. This new polybutylene terephthalate (PBT) plastic will come to the assistance of any design engineer seeking a single pellet, electrically conductive, flame retardant material offering high levels of reliability whenever there is potential for fuel exposure or issues surrounding automotive fluid compatibility, thus providing complete peace of mind for the customer and end user.
Of particular note, at 2.5mm thick, the material has been designated 5VA, the highest flammability rating from UL94, the standard for safety of flammability of plastic materials for parts in devices and appliances. This level of flame retardant performance is obviously essential when the application involves highly flammable fluids. A 5VA rating means burning stops inside 60 seconds on a vertical specimen without dripping (and without creating a hole in the specimen). For those who require a thinner EMI housing, Premier PBT-250FR carries a UL 94 rating of V-0 at 1.5mm thick.
“In ongoing discussions with our partners, one request we kept hearing over and over was how an electrically conductive plastic with a 5VA flammability rating would address a major gap in the marketplace,” states John Beswick, engineered plastics solutions business unit manager, Parker Chomerics.
