PUR Spiral Cables vs. Rubber Spiral Cables
1. Introduction
When choosing a spiral cable, besides the number of cores and the size of the cable, we often need to consider the sheath material of the spiral cable. We usually use PUR (Polyurethane) as the sheath for spiral cables, but some people choose Rubber or PVC. this article focuses on the performance of PUR and Rubber spiral cables.
2. Composition and properties of sheathing materials
PUR Spiral Cable
- Made of Pur sheathed cable, its insulation can be PVC or PE material.
- Commonly used cable models are H05BQ-F H07BQ-F
- Excellent resilience properties and fatigue resistance, abrasion and tear resistance.
- Resistant to oil, gasoline, water, ozone, UV, corrosion resistance is also very good, can be used in chemical factories
- Too tight at low temperatures.
Rubber Spiral Cable
- Made of rubber sheathed cable, usually CPE sheathed with EPDM insulation.
- Commonly used straight cable type is SOOW.
- Remains amazingly flexible even at low temperatures.
- Water, oil and abrasion resistance Outstanding
- Tear resistance is moderate and resilience is poor.
- Tends to lose its original spiral shape over time and requires more maintenance.

3. Environmental & Chemical Resistance Comparison
Property | Rubber | PUR |
Weather Resistance | Very Good | Very Good |
Cold Resistance | Moderate Good | Very Good |
Tensile Strength | 10-20 | 30-45 |
Flexibility | Excellent | Good |
Temperature Range | -40°C to +105°C | -55°C to 80°C |
4. Best Applications for Each Type
PUR Retractable Coil Cord
- Trailer Spiral Cables
- Machine Construction
- Building Industry
- Handling Equipment
- Entertainment Equipment
- Medical devices
- Measurement instruments
- Rolling doors
- EOT cranes
- EV charger
- Mobile Lighting Tower Cable
Rubber Retractable Coil Cord
- Portable tools and equipment, portable appliances
- Small motors and related machinery
5. Conclusion: Which One Should You Choose?
Both Pur and Rubber Retractable Coil Cables have their advantages and disadvantages. However, for the most part, people prefer Pur sheathed cables, which work longer.
