The key to selecting polyurethane cables is based on operating conditions. Shanghai Suoqi polyurethane cables use conductors made of multiple strands of finely twisted oxygen-free bare copper wire, insulation made of special elastomer materials, and an outer sheath of imported polyurethane PUR/TPU, which is oil-resistant, acid- and alkali-resistant, UV-resistant, and aging-resistant. They have core advantages such as corrosion resistance, polyurethane, and TPU, and can be widely applied in chemical, marine, underwater, and other scenarios.

Product Features

(3) Wide Temperature Range Adaptability Low-Temperature Flexibility: Even in extreme cold environments as low as -40°C, the cable maintains good flexibility without hardening or brittleness, ensuring normal use in outdoor operations in cold regions or cold storage and other low-temperature environments, such as in northern winters for open-pit mining equipment and cold chain logistics and transportation equipment power supply.

(3) Sheath: Imported polyether-type TPU as the outer sheath, with a surface hardness of [X] Shore A, offering excellent wear and scratch resistance. The sheath tightly wraps the internal structure, providing excellent corrosion and weather protection while evenly distributing stress during cable bending and stretching, protecting internal conductors and insulation layers from damage. Additionally, sheath colors can be customized according to customer requirements, facilitating line identification and management.

(4) Shielding layer (optional) For applications sensitive to electromagnetic interference, cables can be equipped with aluminum foil and tinned copper wire double-layer shielding structures. Aluminum foil shielding effectively blocks low-frequency electromagnetic interference, while tin-plated copper wire braided shielding effectively suppresses high-frequency interference, achieving or exceeding 85% shielding to ensure stable and accurate signal transmission in strong electromagnetic environments, such as automated production lines and medical equipment where electromagnetic compatibility is required.

3. Diverse Applications to Meet Different Needs (1) Industrial Manufacturing Chemical Production: In the areas of chemical raw material storage and transportation, it is used to connect various pumps, valves, mixers, and other equipment, resisting corrosion from strong acids and alkalis, ensuring continuous and stable operation of production equipment, and preventing production interruptions caused by cable failures.

Food and beverage processing: Meets food-grade hygiene standards. In food processing workshops, it is used for equipment power supply and signal transmission, resistant to frequent cleaning with cleaners and disinfectants, does not release harmful substances, ensures food safety, and meets the requirements for cable flexibility and wear resistance during high-speed production line operation.

Frequently Asked Questions

How to choose between polyurethane cables and PVC cables?

For indoor, dry, low-cost scenarios, PVC can be selected; for oily, outdoor, frequently moving, or long-life requirements, PUR is the priority.

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.
