In chemical and machine tool processing scenarios, cutting fluids, oil stains, and acidic and alkaline media continuously erode cable sheaths, causing general PVC/rubber materials to age and crack rapidly, significantly shortening service life. To address this pain point, Shanghai Suoqi's polyurethane cables have been optimized in both materials and processes: using polyether-type polyurethane outer sheaths, conductors meeting VDE 0295 CLASS 5 standards, and insulating TPV composite materials, suitable for oil-stained, acidic, and alkali corrosive environments. In practical applications, the products have been recognized by customers in automation, production lines, and CNC fields for their high flexibility, polyurethane, and PUR performance.

Product Features

(2) High-flexibility design, suitable for complex dynamic environments Multi-stranded finely twisted conductor structure: The cable conductor is carefully twisted from multiple strands of ultra-fine oxygen-free bare copper wire, complying with VDE 0295 Class 6 conductor standards. This structure gives the conductor extremely high flexibility, easily coping with frequent bending and twisting actions. In multiple bending tests, the cable conductor showed no breakage or damage, ensuring uninterrupted power and signal transmission, making it especially suitable for application scenarios with very high flexibility requirements for cables, such as industrial robot joints and drag chain systems.

Stable Insulation Resistance: The cable's insulation resistance remains stable during long-term use. At an ambient temperature of 20℃, the insulation resistance is ≥1000 MΩ·km per kilometer, effectively reducing the risk of leakage, lowering energy loss, ensuring the accuracy and stability of signal transmission, and meeting the requirements of industrial control systems for high-precision signal transmission.

Connection with the machine tool control system: Connect the CNC system of the machine tool with various functional components, such as the tool magazine and worktable, so that the CNC system can monitor and control the operating status of the machine tool in real time. The highly flexible design can meet the cable bending requirements of the machine tool during complex movements, ensure the timeliness and accuracy of signal transmission, and improve the automation level and processing quality of the machine tool.

Automated sorting equipment connection: Used to connect various components of automated sorting equipment, such as conveyor belt motors and sorting robots, enabling power supply and signal exchange between devices. Its strong environmental adaptability allows it to operate normally in logistics warehouse environments with high dust and oil contamination, ensuring the sorting equipment accurately identifies and sorts goods, improving logistics sorting efficiency and accuracy.

III.

Frequently Asked Questions

What is the temperature resistance of polyurethane cables?

Conventional polyether PUR is suitable for temperatures from -40°C to 90°C, and can be higher in the short term. When selecting, consider ambient temperature and mobile status for confirmation.

Will polyurethane cables hydrolyze?

Ether-based PUR has excellent hydrolysis resistance, far superior to polyester-based types. Ether-based formulations should be specified for long-term humid environments.
