With the rapid growth of new energy vehicles (NEVs) and the electric vehicle (EV) industry, automakers and cable manufacturers are shifting to high-performance cable material solutions to meet strict technical demands.
Beyond cross-linked polyethylene (XLPE), thermoplastic polyurethane (TPU) compounds have emerged as a game-changing material. They offer a unique balance of durability, flexibility, and strong weather resistance.
Angreen New Materials Technology is a CNAS-certified leader in polymer and cable material innovation. The company focuses on premium TPU compounds that improve the durability, safety, and efficiency of EV systems.
Angreen has an annual TPU compound capacity of 15,000 tons and a top-tier R&D team. The team develops high-quality TPU formulations to meet demanding requirements for wire and cable insulation, internal components, and battery housing applications.
NEV systems require materials that perform under heat and stress.
Compared with traditional rubber or PVC, TPU compounds offer:
High tensile strength (20–60 MPa)—withstands vibration and impact.
Excellent abrasion resistance—protects cables and seals from long-term wear.
Wide temperature range (-40℃ to 120℃)—stable in hot battery packs and cold climates.
EV components are often exposed to oils, coolants, and UV radiation.
TPU compounds are well suited for these conditions due to:
Resistance to oils and solvents—critical for BMS and charging cables.
Hydrolysis resistance—prevents degradation in humid environments.
UV stability—maintains integrity of exterior parts.
Lightweight design for extended driving range
TPU compounds have lower density than metals and many plastics.
They offer an excellent strength-to-weight ratio and no corrosion risk, unlike metal alternatives.
TPU compounds play a key role across multiple NEV systems. They deliver tailored solutions for high-performance needs.
Thanks to high dielectric strength and flame-retardant properties, TPU is ideal for high-voltage cable insulation. It helps reduce fire risks in high-energy battery systems.
In battery housing seals, TPU provides flex-fatigue resistance and chemical protection. It shields battery packs from moisture and dust while handling constant compression cycles.
Charging pile cable benefit from TPU abrasion resistance and shape memory. These features help maintain safe electrical connections during repeated charging cycles.

Angreen TPU compounds outperform competitors in flame retardancy, fire safety, wear resistance, and sustainability.
They are well suited for next-generation EV applications, including charging cables, high-voltage cable insulation and jackets, and automotive Ethernet cables.
Angreen develops TPU materials specifically for high-performance electric vehicles, including:
Flame-Retardant TPU—meets UL94 V-0 and IEC 60332-3 battery safety standards.
Micro-bundle tube TPU—designed for optical cables above 3.0 mm and in-vehicle Ethernet cables.
Electrical insulation TPU—prevents short circuits in high-voltage EV systems.
Thermally conductive TPU—improves battery cooling efficiency.
Bio-based TPU—reduces carbon footprint without sacrificing performance.
Supported by advanced research from leading universities in China, Angreen continues to improve its TPU compounds to meet automotive standards such as ISO 6722, SAE J2642, and LV 312-1.
