Global specialty materials and chemicals company Celanese Corporation has announced the global commercial launch of two new polyamide solutions for manufacturers of electric vehicle (EV) powertrain components and EV battery applications.
Excellent flame retardancy and CTI
Frianyl ® PA W series of flame-retardant polyamide solutions enable the manufacture of large, thick-walled flame-retardant components for electric vehicle batteries. With W
series solutions, manufacturers can improve the safety of these components, introduce novel designs and increase manufacturing efficiency. Potential applications include battery module housings, electronic box housings and covers, etc.
W-Series solutions achieve V-0 flame retardancy at 1.5mm with excellent flow characteristics. Compared to standard PA66 grades containing 30% glass fiber reinforcement, the new W
The same grades in the series have improved flowability in injection molds
10-20%, depending on the pressure applied. The improved process means manufacturers can consider new designs and fill molds more easily during machining, potentially shortening cycle times. W
Series solutions also feature outstanding laser marking capabilities for all common laser marking processes.
Additionally, Frianyl ® PA W Series solutions exhibit excellent relative tracking index even after 1,000 hours of aging at 125°C
(CTI). The long-term color stability of parts made from these materials is also remarkable when measured at 125°C, with no changes visible to the naked eye and even nominal changes when measured in a color laboratory.
Electrical-friendly options that can overcome failure challenges
Celanese also launched Celanyl ® PA B3 GF30 E, a new polyamide-based compound for semi-electric and structural electric vehicle powertrain applications. The material grade is available up to HB
Flame rating, CTI reaches 600 even after aging for 3,000 hours at 150°C. Celanyl ® PA B3 GF330 E
The extremely low halide content in the solution makes it an electrically friendly choice for applications such as connectors, switches, relays, busbars and sensors where failure or short circuiting may occur when voltage is applied.
Failure is usually caused by three factors: surface moisture, elevated temperatures, and trace amounts of halide ions (such as chlorine, bromine, or iodine) that can cause electrolytic corrosion. Celanyl ® B3 GF330 E
Solutions help manufacturers overcome these performance challenges.
The Frianyl ® PA W range and Celanyl ® PA B3 GF30 E solutions are now available globally.
