German sports electric car uses Lanxess (pinfa member) non-halogenated flame retardant nylon for charger heat dissipation. The charging system manufacturer is Leopold Kostal GmbH, Luedenscheid, Germany, a global automotive, solar and electrical contact system supplier. Up to 48 amps flow through plug contacts in the controller during EV battery charging. The PIN FR nylon 6 compound uses a special mineral filler to conduct heat, so avoiding overheating. The compound also offers reliable electrical insulation (CTI A 600) and fire resistance (UL 94 V-0 0.75 mm) to ensure safety. Mechanical performance, dimensional stability and good flowability enable production of intricate, miniaturised components. The heat-conductive PIN FR nylon compound also has applications in EV battery systems and heat exchangers and mounting plates for electronics.
