Celanese launches new PA solutions to improve performance of electric vehicle components

Celanese Corporation, a global speciality materials and chemical company, announced on 16 Oct 2023 the global commercial launch of two new polyamide (PA) solutions for manufacturers of electric vehicle (EV) powertrain components and EV battery applications. The Frianyl PA W-Series of flame-retardant PA solutions enables the manufacturing of large, thick-walled, flame-retardant components for EV batteries. With the W-Series solutions, manufacturers can improve the safety of these components, introduce novel new designs and enhance manufacturing efficiency. Potential applications include battery module housings, e-box housings and covers, and more. The W-Series solutions achieve V-0 flame retardance at 1.5 mm, combined with excellent flow characteristics. Compared to standard PA66 grades with 30% glass fibre reinforcement, the equivalent grade of the new W-Series offers a 10-20% improvement in flow in an injection mould, depending on the pressure applied. Improved flow means manufacturers can consider new designs and more readily fill moulds during processing, potentially leading to cycle time reductions. The W-Series solutions also have excellent laser markability with all common laser marking processes. In addition, the Frianyl PA W-Series solutions exhibit an excellent Comparative Tracking Index (CTI) even after aging at 125 degC for 1000 hours. Long-term colour stability of parts manufactured from these materials, measured at 125 degC, is also notable with no visible change to the eye, and even only a nominal change when measured in a colour lab. Celanese also introduced Celanyl PA B3 GF30 E, a new PA-based compound for semi- and structural EV powertrain applications. With this grade, the HB flame class is achieved, as well as a CTI of 600 even after 3000 hours of aging at 150 degC. The extremely low halide content in the Celanyl PA B3 GF330 E solution makes it an electrically friendly option for applications like connectors, switches, relays, busbars and sensors that can malfunction or short circuit when voltage is applied. Malfunctions often occur because of three factors: surface moisture, elevated temperature and traces of halide ions such as chlorine, bromine or iodine that can lead to electrolytic corrosion. The Celanyl B3 GF330 E solution helps manufacturers overcome these performance challenges. The Frianyl PA W-Series and Celanyl PA B3 GF30 E solutions are now commercially available globally.
