In recent years, TPU materials have gradually been replacing PVC and chloroprene rubber in cable applications. Although the overall consumption of TPU in the cable industry is relatively small, it offers superior environmental and recycling properties. In demanding environments, TPU materials are the preferred choice for cable sheathing. TPU combines the processing ease and dimensional stability of plastics with the elasticity and wear resistance of rubber, making it an ideal material for cable sheaths and insulation layers.
Thermoplastic polyurethane (TPU) is widely used for cable sheathing in voltage ranges up to 1KV, primarily due to its excellent mechanical and physical properties. TPU exhibits outstanding toughness and rigidity, flexibility at low temperatures, superior abrasion resistance, and exceptional environmental and weather resistance. These attributes significantly enhance cable durability and service life.
Cable Sheathing: TPU materials are widely used for cable sheathing due to their excellent elasticity and abrasion resistance. They provide effective protection for internal conductors and insulation layers against external damage while offering a good grip and aesthetic appearance.
Insulation Layer: In specialized cable applications, TPU materials are also used as insulation layers. Their superior insulating and heat-resistant properties allow them to meet the requirements of high-temperature and high-frequency environments.
Halogen-Free Flame-Retardant Cables: With increasingly strict environmental regulations, the demand for halogen-free flame-retardant cables is growing. TPU materials serve as an ideal carrier for halogen-free flame retardants, demonstrating great potential in the production of environmentally friendly flame-retardant cables.
As a high-performance and environmentally friendly polymer material, TPU materials play a significant role in the cable industry. With continuous advancements in technology and the expanding market demand, TPU is expected to become even more critical in the electrical cable sector.
