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

XLPE for Wires and Cables
Crosslinked polyethylene (XLPE) is a thermoset polymer engineered via chemical/peroxide or radiation crosslinking, enhancing thermal/mechanical properties over standard PE.
Critical Advantages
Thermal Stability: Continuous operation up to 180°C (vs. PE’s 75°C), resistant to thermal deformation.
Electrical Performance: Ultra-low dielectric loss, high insulation resistance (IEEE 48 standards).
Durability: Superior tensile strength, abrasion/chemical resistance, and reduced water treeing.
Key Applications
Energy Infrastructure: HV power cables (>500 kV), solar/wind farm wiring.
Industrial Systems: Fire-resistant building wires, submarine cables, and automotive harnesses.
Processing: Cured at 160–200°C; recyclable via thermoplastic conversion tech.
