PUR Cable: The Ideal Choice For Durability And Flexibility

PUR Introduction ：

Choosing the right cable material is crucial in modern industrial applications.

PUR (polyurethane) sheathed cable has become the preferred choice across many industries due to its superior performance, particularly for applications requiring high flexibility, high abrasion, and high mechanical stress.

This article will introduce the core performance, advantages, and typical applications of PUR cable to help you gain a deeper understanding of the advantages of this advanced material.

Key Performance Benefits Of PUR Cable :

1. Heat Resistance

PUR cable is suitable for extreme temperature environments.

With a short-term temperature resistance range of -40°C to +120°C and a long-term operating temperature of up to 90°C, it is ideal for high-temperature environments and spiral cable applications.

2. Excellent Hydrolysis Resistance

PUR sheathing offers excellent water resistance, maintaining stable mechanical strength even in high humidity or prolonged submersion.

For example, after immersion in water at 72°C for 20,000 hours, its tensile strength remains above 20 N/mm², meeting industrial standards.

3. Excellent Weather Resistance

Ordinary cables can become brittle and discolor when exposed to UV rays or sunlight.

PUR cables, by adding UV stabilizers and antioxidants, effectively resist UV and ozone damage, making them particularly suitable for outdoor applications and complying with VDE 472-805.

4. Microbial Resistance

PUR cables with a polyether polyurethane jacket effectively resist microbial attack and are unaffected by mold, mildew, and corrosion, complying with European standards such as DIN 57472 / VDE 472-804.

5. Excellent Flame Retardancy And Low Toxicity

Although PUR does not contain natural flame retardants, improved formulations can meet the requirements of standards such as VDE ξ804, UL94 HB, and FMVSS 302.

Furthermore, PUR is halogen-free, low in smoke, and low in toxicity, releasing far fewer harmful gases in a fire than traditional PVC cables, further complying with EU environmental regulations.

6. Strong Resistance To Grease, Oil, Acids, And Alkalis

PUR cables are resistant to a variety of oils and lubricants, making them particularly suitable for use in oily and contaminated environments such as welding, machining, and automotive manufacturing.

However, please note that its resistance to strong acids and alkalis is limited, making it suitable only for short-term exposure.

PUR Cable Application Advantages And Usage Recommendations

PUR is a highly flexible thermoplastic elastomer with excellent mechanical properties.

It is widely used in robotics, automation equipment, medical devices, CNC machine tools, coating equipment, and other fields.

Why Choose PUR Cable?

High Flexibility: Remains flexible even at low temperatures, making it suitable for environments with frequent movement and tight bend radii.

Abrasion and Tear Resistance: Suitable for cable carriers and drag chain systems.

Resistant to cutting fluids, welding slag, and oil stains: Ideal for demanding industrial environments such as stamping lines and automated welding lines.

Eco-Friendly Halogen-Free Design: RoHS and REACH Compliant, safer and more environmentally friendly.

Summary :

Whether in industrial automation, machinery manufacturing, or the medical and robotics industries, PUR cable, with its outstanding abrasion resistance, flexibility, environmental friendliness, and weather resistance, provides a more efficient and secure cabling solution.

If you are facing complex and dynamic cabling environments or looking for a high-performance alternative to traditional PVC cables, PUR cable is undoubtedly the ideal choice.
