In chemical, machine tool processing, and other scenarios, cutting fluids, oil stains, and acidic or alkaline media continuously corrode cable sheaths, causing general PVC/rubber materials to age and crack quickly, significantly shortening their service life. To address this issue, Shanghai Suoqi has optimized its polyurethane cables both in materials and processes: the conductors are multi-stranded, finely twisted, oxygen-free bare copper wires; the insulation is made of special elastomer materials; the outer sheath is imported polyurethane PUR/TPU, which is oil-resistant, acid and alkali-resistant, UV-resistant, and aging-resistant. In actual applications, the products have been recognized by customers in the mechanical, steel, and automation sectors for their polyurethane, tensile strength, and PUR performance. Customization according to drawings and direct shipment from stock are supported. For details, please contact 13311756197.

Mechanical properties

Cable insulation materials are generally not subjected to high mechanical stress. On the other hand, sheaths are used extensively. This is especially suitable for flexible control and connection cables, which are often pulled over sharp corners and rough surfaces. This can lead to protruding cuts when stretching cables during flexible use. Compressive stress caused by squeezing and impacts by tools and machines may also occur.

The outstanding chemical properties of polyurethane cables are

1. Has good resistance to mineral oils 2. Has good resistance to non-alcohol gasoline 3. Has good resistance when stored in water 4. Has good resistance to many solvents Chemical example: 1. After long-term exposure to humid and warm conditions, polyester-type polyurethane is at risk of microbial degradation.

Frequently Asked Questions

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.

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.
