TPE (Thermoplastic Elastomer) as a cable material for new energy vehicle charging piles has the following advantages:
Simple processing technology: TPE material is easy to process and can be extruded by common thermoplastic material processing methods, which improves production efficiency.
Low density: TPE cable is relatively light and easy to install and wire.
Moderate price: Compared with other high-performance materials, TPE cable materials are more cost-effective.
Soft overall cable: TPE material provides good softness, making the cable easy to bend and operate, especially in occasions where frequent movement or bending is required.
Temperature resistance: TPE cable can maintain stable performance over a wide temperature range, generally cold-resistant temperature up to -50°C, temperature resistance up to 120°C.
Chemical resistance: TPE material has good tolerance to a variety of chemicals, including acids, alkalis and oils.
Weather resistance: TPE cable can be used for a long time in outdoor environments and has good UV and ozone resistance.
Environmental protection characteristics: TPE material does not contain halogens, produces less toxic gases when burned, and meets environmental protection requirements.
Wear resistance: TPE material has a certain wear resistance and is suitable for use in environments where it may be subject to wear.
Flexibility: The flexibility of TPE cable material makes it more convenient during installation, especially when frequent bending is required between the vehicle charging port and the charging pile.
