Modified Materials For Wires And Cables

TPE TPU for EV Charging Cables

TPU for EV Charging HV Cables ‌Thermoplastic polyurethane (TPU)‌ elastomers enable flexible, high-reliability insulation/sheathing for DC fast-charging cables (>500V), meeting IEC 62893 standards. ‌Critical Performance‌ ‌Electrical Safety‌: Halogen-free formulations achieve ‌≥30 kV/mm‌ dielectric strength and V-0 flame rating (UL 94). ‌Extreme Environment‌: Retains flexibility (-40°C to 125°C), resists oils, UV, and hydrolysis. ‌Durability‌: Withstands >10,000 bend cycles and mechanical abrasion. ‌Material Advantages‌ ‌Processing‌: Extrusion at 195–220°C; recyclable vs. thermoset alternatives. ‌Sustainability‌: Bio-based TPU options (e.g., BASF Elastollan®, Arkema EcoPaXX®) reduce carbon footprint. ‌Applications‌ Insulation layers for 150–1000V DC cables Protective outer jackets in CCS2/CHAdeMO connectors
