As a cable material for charging cables of new energy vehicle charging piles, TPU (thermoplastic polyurethane) has a series of significant advantages, making it an ideal choice for this application:
Abrasion resistance: TPU material has excellent abrasion resistance, which is essential for the durability of charging cables in frequent use.
Mechanical strength: TPU has high tensile strength and tear resistance, which can effectively resist physical damage that may be encountered during use.
Chemical resistance: TPU has excellent tolerance to oils and many chemicals, suitable for use in various environmental conditions.
Low temperature and heat resistance: TPU materials can maintain good performance in a wide range of temperatures, from extremely low cold temperatures to higher operating temperatures.
Flexibility: TPU cable material is soft and easy to install and wire, especially when frequent bending and movement are required between the vehicle charging interface and the charging pile.
Environmental characteristics: TPU is an environmentally friendly material that does not contain halogens, which meets the current demand for green and sustainable materials.
Halogen-free flame retardant: TPU materials usually have halogen-free flame retardant properties, which helps to improve the safety of charging piles and charging cables.
Weather resistance: TPU materials can resist the influence of ultraviolet rays and adverse weather conditions, and are suitable for long-term outdoor exposure.
Oil resistance: TPU has good resistance to oils and can maintain stable performance even in oily environments.
Economical: Although the cost of TPU materials is relatively high, its excellent performance and durability reduce long-term maintenance costs and have good economical efficiency.
