Overview: 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. For reference:

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.

Cable materials have 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 materials have excellent wear resistance, and their 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.

Cable products have excellent oil and water resistance: Electric vehicle cables may be exposed to various oils and moisture during use, so the material is required to have excellent oil and water resistance. TPU material has better oil resistance than nitrile rubber and has an excellent oil resistance life; at the same time, TPU also has good waterproof performance, which can effectively prevent the cable from being damaged by moisture erosion.

Excellent flame retardant performance: 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 performance of the cable can be significantly improved, ensuring that the cable will not burn and spread rapidly in extreme situations such as fire, thereby ensuring the safety of vehicles and personnel.

Among them, 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 more powerful guarantee for the safe and reliable operation of electric vehicles. At the same time, we also look forward to more applications and innovations of high-performance materials in the field of electric vehicle cables to promote the sustainable and healthy development of the electric vehicle industry.
