Product Description
Product description: As a key component of electric vehicle charging and power transmission, electric vehicle cables’ performance and quality are crucial. Thermoplastic polyurethane elastomer (TPU), as a high-performance material, has been widely used in the production of electric vehicle cables. This article will introduce in detail TPU materials and their applications in electric vehicle cables.
Product material: TPU is an (AB) n-type block linear polymer, composed of flexible soft segments and rigid hard segments. In its molecular structure, A is a high molecular weight polyester or polyether, B is a diol containing 2 to 12 linear carbon atoms, and the chemical structure between AB segments is diisocyanate. TPU has excellent comprehensive properties such as high strength, high toughness, wear resistance, and oil resistance. It has good processing performance, is recyclable, and has excellent environmental performance.
Excellent wear resistance:
Electric vehicle cables need to withstand various friction and wear during use, so wear resistance is one of the important performance indicators of the cable. TPU material has excellent wear resistance and its Taber wear value is extremely low, which is the smallest among plastics. This makes TPU an ideal choice for electric vehicle cable sheathing materials, which can effectively extend the service life of the cable.
Good high and low temperature resistance:
Electric vehicle cables need to work in different ambient temperatures, so the materials are required to have good high and low temperature resistance. TPU material can maintain good physical properties and elasticity in the temperature range of -62°C to 120°C, which allows TPU cables to work normally under extreme climate conditions.
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 a 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.
To sum up, 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 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.
