对常见电池电解质有良好的抵抗性
该混合物对机动车辆中使用的典型介质（如燃料，油，清洁剂和汽车护理产品）具有很强的抵抗能力，这在Lanxess为海拉胡克进行的广泛的介质储存测试中得到证实，符合供应规范LV 124，这一被许多汽车制造商认定的标准。该材料还显示出对广泛用于锂离子电池的电解质的良好抗性，对此也按DIN EN22088-3进行了负载测试。“样品即使在1,000小时的曝光后也没有明显的裂缝，还可以使用。”Marbach表示。
综合性的HiAnt服务
Lanxess在研发外壳组件方面为海拉胡克提供了额外的支持。这些服务是HiAnt客户服务包的一部分。例如，HPM提供了优化组件设计的建议，提供所有外壳组件电脑辅助设计是需要的材料性能数据以满足预期负载并进行模流分析，帮助进行起初的注塑成型试验。这家特种化学品公司进一步通过离子色谱法为Hella确定了混合物中卤化物含量，并对VDA 270进行了气味测试。

LANXESS launches new PBT compound for battery components in electric cars
S
pecialty chemicals company LANXESS has developed a new compound called Pocan AF4130 in collaboration with HELLA KGaA Hueck & Co., based in Lippstadt, Germany. It serves as a housing material for a battery management unit (BMU) and two cell monitoring units (CMU).
The blend of polybutylene terephthalate (PBT) and acrylic ester-styrene-acrylonitrile (ASA) contains 30 percent by weight glass fibers and a halogen-based flame retardance package. “The particular advantages of the material are its extremely low warpage and shrinkage, combined with its high flame retardance. We see great potential for application in precision components for vehicle battery systems,” says Marc Marbach, head of Sales Segments E&E in the LANXESS High Performance Materials (HPM) business unit. It took just two-and-a-half years to go from the initial idea to extensive testing and finally to use in full-scale production.
HELLA fabricates the BMU and CMUs for a German manufacturer of battery systems for motor vehicles. The very flat devices currently are used in the lithium-ion battery system of a German compact car.
