Polyurethane Cable (TPU/PUR Sheath) Product Details
In modern industrial and complex environmental applications, cables need to face rigorous tests, with high requirements for performance and reliability. The polyurethane (TPU/PUR) sheathed cables launched by Shanghai Suoqi stand out with their excellent material performance and advanced technology, becoming a trusted choice for many industries.
1. Outstanding performance, forging extraordinary quality
(1) High temperature resistance and stable operation
Ordinary plastic raw materials are prone to oxidation at temperatures above 70°C, whereas our TPU/PUR sheathed cables demonstrate exceptional high-temperature resistance. TPU materials can generally withstand temperatures up to 120°C, and under such high-temperature conditions, the cable's electrical and physical properties remain stable, effectively preventing issues such as sheath softening and increased conductor resistance. This makes them excellent for power supply and signal transmission in high-temperature workshops such as metallurgy and glass manufacturing, ensuring continuous and efficient operation of the equipment.
(2) Super wear-resistant and durable
PUR material is renowned for its excellent wear resistance and performs particularly well in high-flexibility cable applications, capable of withstanding over 20 million or even 50 million bending cycles. In scenarios such as industrial automation production lines and CNC machines, where equipment bends and moves frequently, TPU/PUR jackets can effectively resist friction on internal components. According to Taber abrasion testing (CS-17 wheel, 1000g load), the wear is minimal, significantly extending cable service life, reducing equipment maintenance costs, and saving enterprises a substantial amount of time and money.
(3) Resistant to cold and low temperatures, not afraid of severe cold
In the aerospace field, TPU and PUR materials are highly favored for their excellent cold resistance. Our cables offer transmission stability far beyond other materials in low-temperature environments, and even at working temperatures as low as -40°C, they can maintain good flexibility and electrical performance, without hardening or cracking. Whether for cold storage, polar operation equipment, or power and signal connections for outdoor equipment in northern winter, they can easily cope, ensuring normal operation of the equipment in extreme low-temperature conditions.
(4) Oil-resistant characteristics, suitable for complex environments
Both TPU and PUR have excellent oil resistance, are not easily corroded by oil stains, and are odorless and non-toxic, meeting environmental standards. In industries such as food and beverage processing and chemical production, cables must not only withstand oily environments but also ensure food safety and avoid contamination. The oil-resistant and easy-to-heat-seal performance of this cable ensures that its performance is not affected when frequently exposed to greasy substances, providing reliable support for the production process, while being safe and environmentally friendly, meeting the strict requirements of modern enterprises for the production environment.
2. Scientific structure ensures excellent quality
(1) Conductors
Using multi-stranded ultra-fine refined oxygen-free bare copper wire with a purity of ≥99.99%, meeting VDE 0295 CLASS 5/6 standards, it has low resistance characteristics, which can effectively reduce energy transmission losses. The multi-stranded twisted structure gives the conductor flexibility and elasticity, enhancing the overall flexibility and bending lifespan of the cable, ensuring stable and efficient power transmission in complex usage environments.
(2) Insulation layer
Specially modified insulating materials, combining good electrical insulation performance with mechanical properties. While ensuring high dielectric strength (≥[X] kV/mm) and insulation resistance (≥[X] MΩ·km, 20℃), they possess excellent flexibility and temperature resistance, with an operating temperature range of -40℃ to 120℃, meeting the requirements for stable operation under different environmental temperatures and providing a solid defense for the safe operation of cables.
(3) Sheath
The TPU/PUR outer sheath has a surface hardness of [X] Shore A, which not only gives it a bright appearance but also provides excellent wear resistance, chemical corrosion resistance, and low-temperature performance. It tightly wraps the internal structure, offering comprehensive protection to the conductor and insulation layer during cable bending, stretching, and friction, effectively resisting various external adverse factors that may damage the cable's internal structure.
(4) Shielding layer (optional)
For application scenarios sensitive to electromagnetic interference, such as automated production lines and medical equipment, it can be equipped with a tinned copper wire braided shielding layer or an aluminum foil-tinned copper wire double-layer shielding structure. The shielding coverage is ≥85%, effectively shielding external electromagnetic interference, ensuring stable and accurate cable signal transmission, meeting the strict electromagnetic compatibility requirements of the equipment, and enabling zero-interference signal transmission.
3. Diverse applications to meet different needs
(1) Industrial Automation
Industrial robot system: On the wrist of the six-axis robot, the cable must withstand a torsion of ±180°/m. This cable uses a spiral winding design to meet its high torsion requirements; The seventh-axis track cable has a tensile strength of >150N/mm², adapting to continuous stretching during track movement, ensuring flexible and stable robot operation and enhancing industrial production automation.
CNC machine tools and machining centers: tool magazine drag chain cables resist cutting oil penetration, with a bending radius of ≤7.5×D (D is the cable outer diameter), maintaining stability during frequent tool changes and equipment movements; The spindle cooling system cables withstand temperatures up to 125°C, matched with high-pressure coolant environments to ensure efficient equipment operation and support precision operations in the machining industry.
(2) Logistics automation
Sorting robot cables: Anti-static coating is added on the surface (resistance value 10^6 - 10^9Ω) to prevent package adhesion. During high-speed sorting, the cable's high flexibility and wear resistance ensure frequent bending and movement are unaffected, improving sorting efficiency and optimizing logistics distribution processes.
Stacker crane roll cable: resistant to vertical lifting impact, with a bending service life of > 5 million cycles. During frequent lifting and movement operations, it reliably transmits power and signals, ensuring smooth logistics warehousing operations and providing strong support for efficient operation in the logistics industry.

Photovoltaic string welding machine cables: UV-resistant and durable, with an outdoor service life of > 10 years. In outdoor photovoltaic power stations, they can maintain good performance even after long-term exposure to sunlight, ensuring stable collection and transmission of photovoltaic energy, and promoting the vigorous development of the new energy industry.
(4) Special Environment Operations
Offshore wind power equipment: In the connection between offshore wind turbine towers, nacelles, and hubs, weather-resistant and anti-aging TPU/PUR sheaths resist corrosion from harsh offshore environments, adapt to turbine vibration and oscillation, and ensure stable transmission of power and control signals; On offshore wind power platforms, as power supply and communication cables for various equipment, they maintain excellent electrical and physical performance in high salt spray and humid environments, providing solid support for the stable development of offshore wind power.
Mining equipment: In electric loaders, mining cranes, and other equipment, cables must withstand high mechanical stress and harsh environmental conditions. The cable's high strength and wear resistance, oil contamination resistance, waterproofing, and acid and alkali corrosion resistance enable reliable operation under complex mining conditions, ensuring smooth mining operations and contributing to safe and efficient mining production.
