LANXESS Announces New PBT Alloy Materials for Battery Parts for Electric Vehicles

On July 21, 2017, Shanghai — LANXESS, a leading specialty chemicals company, in collaboration with the Hella Hook Group from Lippstadt, Germany, introduced a groundbreaking composite material called Pocan AF4130. This innovative PBT (polybutylene terephthalate) and ASA (acrylonitrile-styrene-acrylate) alloy is specifically designed for use in housing components of battery management units (BMUs) and dual battery detection units (CMUs). The material contains 30% glass fiber and a halogen-based flame retardant, making it ideal for high-performance automotive applications. Marc Marbach, Sales Director of LANXESS's High Performance Materials (HPM) business unit, highlighted the material’s key advantages: "This PBT/ASA alloy offers extremely low warpage and shrinkage, along with excellent flame resistance. We believe it has significant potential in precision parts for electric vehicle batteries." The development of this material took just two and a half years, from initial concept to full-scale production. It was developed in response to the needs of a German automotive battery system manufacturer, which relies on Hella for BMU and CMU components. These parts are thin and used in lithium battery systems of compact German vehicles. One of the main challenges was achieving tight dimensional tolerances, as the connector pins must remain straight when mounted on printed circuit boards. The Pocan AF4130 alloy, with its superior dimensional stability, ensures that the fit between connectors and pin jacks remains precise. In terms of safety, the material passed the UL94 fire test, achieving the V-0 rating at 0.75 mm thickness, meeting the stringent requirements of the German car manufacturer. It also holds UL 94 5VA certification at 1.5 mm thickness, and is UL r1 certified for outdoor use, offering UV and water resistance. This makes it suitable for electronic components like photovoltaic plugs and sockets. Another important feature is its low volatility and emissions. According to VDA 278 testing, the thermoplastic material emits very little, making it suitable for interior automotive parts where low emissions are required. Additionally, the material shows strong resistance to common battery electrolytes and automotive fluids such as fuels, lubricants, and cleaning agents. Testing according to DIN EN 22088-3 confirmed that the samples showed no significant cracks after 1,000 hours of exposure, demonstrating its long-term durability. LANXESS also provided comprehensive support through its HiAnt service package. This included design optimization, CAD modeling, and mold flow analysis to ensure the component met all performance requirements. The company also conducted ion chromatography tests to determine halide content and odor testing according to VDA 270. With its combination of performance, safety, and reliability, Pocan AF4130 represents a major step forward in materials for electric vehicle battery systems.
