PUR Cables
Leading manufacturer of PUR (Polyurethane) Cables
At CDC, we manufacture and supply PUR (Polyurethane) cables, sometimes referred to as TPU (Thermoplastic Polyurethane). These cables are valued for their durability, flexibility, and resistance to challenging environments. By processing PUR in multiple polymer grades, we provide customers with a wide range of options to meet demanding design and performance requirements.
We can help you specify and manufacture a solution that fits your application. Whether you need a PUR control cable for automation, a PUR cable jacket for high wear, custom PUR cable insulation for telecoms, or specialised PUR cable material for offshore energy, we can manufacture to your requirements.
What is a PUR cable?
A PUR cable is any cable that uses polyurethane as a jacketing or insulation material. Polyurethane combines flexibility with strength. This makes it well suited for applications where cables face repeated bending or exposure to harsh environments.
The PUR cable jacket is typically used as the outer sheath, protecting internal insulation and conductors. A PUR cable insulation layer can also be specified when thermal or mechanical performance is important. In both cases, polyurethane provides protection without affecting flexibility.
Because it is a thermoplastic material, polyurethane can be manufactured in various grades to cater to specific industries. Flame-retardant, matte-finish, transparent, and high-temperature versions are all available.
Benefits of PUR cable material
Polyurethane is frequently chosen over other cable materials because it consistently performs well in tough conditions.
Durability and resistance
- High tensile strength with resistance to abrasion, cuts, tears, vibration, and impacts.
- Excellent stress-crack, anti-kink, and anti-ageing behaviour.
- Stable material performance across repeated movement cycles.
Flexibility and temperature stability
- Remains flexible at low temperatures (down to -40 °C).
- Maintains performance in heat up to 120 °C.
- Elastic properties make it suitable for drag chain and coiled applications.
Environmental and compliance benefits
- Resistant to oil, weathering, and microbial attack.
- Hydrolysis resistant and impervious to water and humidity.
- Halogen- and plasticiser-free.
- Fully compliant with RoHS and REACH directives.
PUR control cables and automation uses
Modern automation needs cabling that can withstand constant motion, chemical exposure, and tight bend radii. A PUR control cable is designed for precisely these conditions.
Applications include:
- Robotic arm cables for continuous movement.
- Drag chain cables used in automated production lines.
- Power and sensor cables for industrial robots.
In these situations, PUR cable insulation and sheathing offer a combination of oil resistance and flexibility that PVC or rubber alternatives can’t match.
PUR cable applications across industries
Due to their versatility and durability, Polyurethane cables are widely used in sectors where reliability is important.
Automotive
Vehicles need cables that resist oil, fuel, acids, and fluctuating temperatures. PUR cables are used in sensor cabling for anti-lock braking systems (ABS), electronic stability programmes (ESP), battery leads, coiled cables, and harness assemblies.
Automation and robotics
Manufacturing relies on continuous production. PUR cables deliver the necessary flexibility and mechanical endurance for robots, automated systems, and drag chains.
Telecommunications and defence
In environments where continuous data flow is critical, PUR jacketing is used on fibre optic cables and military-grade communications cables. Its resistance to abrasion and moisture ensures consistent performance.
Energy and infrastructure
From offshore wind farms and mining to mass transit and solar power, PUR cabling is relied upon in exposed and harsh settings. Applications include control cables for wind farms, power cables for offshore platforms, solar connectors, submersible vehicle cables, and elevator or escalator cabling.
PUR vs PVC cable
One of the most common questions is how PUR vs PVC cable performance compares.
PVC (polyvinyl chloride) is a cost-effective material widely used in cable jackets. It performs well in standard indoor environments. But it can harden or crack when exposed to low temperatures, oils, or continuous movement.
In contrast, PUR cable material is designed for higher mechanical stress, wider temperature ranges, and exposure to chemicals. PUR cables are typically more expensive. But they last significantly longer in demanding environments, reducing the need for frequent replacements.
PUR cable design and options at CDC
We work with customers to design PUR cables that meet their exact specifications. Options include:
- Different PUR grades – flame retardant, matte, transparent, and high-temperature.
- Custom constructions – single-core, multicore, screened, braided, or coiled.
- Application-specific properties – low-friction jackets for drag chains, oil-resistant insulation for automotive, or hydrolysis-resistant grades for offshore use.
By drawing from a comprehensive material and component library, we can advise on the best PUR cable insulation and jacketing materials for your project.
Standards and compliance
All PUR cables manufactured by CDC are designed and tested to national, international, and industry standards. Our processes meet ISO 9001:2015, and we hold UL and CSA approvals. Materials are certified to RoHS and REACH directives, ensuring that PUR cable jackets and insulation are free from hazardous substances.
Each project includes traceability and documented quality assurance. So, you can be confident that your PUR cables meet performance and compliance requirements.

PUR Cable FAQs
What does PUR mean in cables?
PUR stands for Polyurethane; a thermoplastic material used for cable insulation and jackets. It is valued for flexibility, mechanical resistance, and chemical stability, making it suitable for tough industrial and outdoor applications.
What are the advantages of PUR over PVC?
Compared with PVC, PUR cables provide better flexibility at low temperatures. They also offer higher resistance to oils and chemicals, and longer service life under mechanical stress. PVC is cheaper, but PUR is the stronger choice for demanding environments.
Can PUR cables be used outdoors?
Yes. PUR jackets resist UV, water, and microbial attack, making them suitable for outdoor and underground installations. Hydrolysis-resistant grades ensure performance even in constant humidity or submerged applications.
Are PUR cables halogen-free?
Yes. Polyurethane is halogen-free and does not release corrosive gases when exposed to fire. This property helps meet safety standards in enclosed environments like transport systems and industrial plants.
What temperatures can PUR cables handle?
Standard PUR cables perform from -40 °C to +120 °C. Specialised high-temperature grades are available where additional heat resistance is needed.
