Explore the innovative application of TPU materials in electric vehicle cables

China [CN]

Description: As a key component for electric vehicle charging and power transmission, the performance and quality of electric vehicle cables are crucial. As a high-performance material, thermoplastic polyurethane elastomer (TPU) has been widely used in the production of electric vehicle cables. This article will introduce TPU materials and their applications in electric vehicle cables in detail.

Product material: TPU is a (AB) n-type block linear polymer consisting of a flexible soft segment and a rigid hard segment. In its molecular structure, A is a high molecular weight polyester or polyether, B is a diol containing 2 to 12 straight-chain carbon atoms, and the chemical structure between the AB segments is diisocyanate. TPU has excellent comprehensive properties such as high strength, high toughness, wear resistance, and oil resistance, good processing performance, and can be recycled and reused, and has excellent environmental protection performance.

Excellent wear resistance: Electric vehicle cables need to withstand various frictions and wear during use, so wear resistance is one of the important performance indicators of cables. TPU material has excellent wear resistance, and its Taber abrasion value is extremely low, which is the smallest among plastics. This makes TPU an ideal choice for electric vehicle cable sheath materials, which can effectively extend the service life of the cable.

Good high and low temperature resistance:

Electric vehicle cables need to work at different ambient temperatures, so the material is required to have good high and low temperature resistance. TPU materials can maintain good physical properties and elasticity in the temperature range of -62℃ to 120℃, which enables TPU cables to work normally under extreme climatic conditions.

As a power transmission component, the flame retardant performance of electric vehicle cables is directly related to the safety of the vehicle. After adding environmentally friendly or halogen-free flame retardants to TPU materials, the flame retardant properties of the cables can be significantly improved, ensuring that the cables will not burn and spread rapidly in extreme situations such as fire, thereby ensuring the safety of vehicles and personnel.

The production process of TPU electric vehicle cables mainly includes material preparation, extrusion molding, cooling and shaping, winding and packaging. Among them, extrusion molding is the key link, and parameters such as extrusion temperature, pressure and speed need to be strictly controlled to ensure the quality and performance of the cable.

In summary, TPU materials have been widely used in the production of electric vehicle cables due to their excellent wear resistance, high and low temperature resistance, oil and water resistance, flame retardancy and environmental protection. With the continuous development of the electric vehicle market and the continuous advancement of technology, the performance and quality of TPU electric vehicle cables will continue to improve, providing a stronger guarantee for the safe and reliable operation of electric vehicles. At the same time, we also look forward to the application and innovation of more high-performance materials in the field of electric vehicle cables to promote the sustainable and healthy development of the electric vehicle industry.
