Polycaprolactone TPU Cable Jacket & Coil Cord | Low-Temperature, Flexible, Abrasion-Resistant
Polycaprolactone TPU Cable Jacket & Coil Cord
Polycaprolactone-based TPU compounds designed for cable jackets and spiral coil cords that require excellent low-temperature flexibility, abrasion resistance, hydrolysis resistance and long-term elastic recovery.
Ideal for power cables, signal lines, robotics cables and spring-type coil cords.
Abrasion-Resistant
Hydrolysis-Resistant
Elastic Recovery
Shore 85A–45D
Applications
PCL-TPU cable jacket grades are used where flexibility, mechanical strength and surface durability are required:
- Electrical cable jackets for industrial automation and power tools.
- Signal and control cables requiring resistance to bending fatigue.
- Robotics cables exposed to drag chains or repeated flexing.
- Spiral (coil) cords where long-term elastic recovery is essential.
- Outdoor and cold-environment cables with excellent low-temperature performance.
Typical Grades for Cable Jackets
| Grade | Hardness | Key Performance | Processing | Typical Use |
|---|---|---|---|---|
| PCL-TPU Cable 85A | 85A | Soft, flexible, good abrasion and bending resistance | Cable extrusion | Flexible power and control cables |
| PCL-TPU Cable 90A | 90A | Balanced toughness and flexibility, hydrolysis resistance | Cable extrusion | Outdoor and cold-environment cables |
| PCL-TPU Cable 40D | 40D | Higher stiffness, abrasion resistance, elastic recovery | Extrusion / coil cord forming | Spiral coil cords and durable jacket layers |
Note: Grades are for reference only. Custom stiffness, tensile profile and color options are available for OEM cable structures.
Key Advantages
- Excellent abrasion resistance for drag chain and moving cable applications.
- Low-temperature flexibility for cables used outdoors or in refrigerated environments.
- High elastic recovery for spiral (coil) cords.
- Hydrolysis and moisture resistance for long service life.
- Smooth surface finish for easy sliding and low friction in cable chains.
Processing & Recommendations
PCL-TPU cable grades are engineered for stable extrusion with excellent melt strength:
- Extrusion conditions: 185–210 °C depending on jacket thickness and hardness.
- Drying: 80 °C × 2–3 hours for stable extrusion and smooth surface.
- Coil cords: 40D grade recommended for spring memory and recovery.
- Color: natural, black, matte or glossy surface available upon request.
