What are the benefits of PUR cables?

PUR or Polyurethane has been used for cable sheathing since the 1960’s and is a thermoplastic material with superior physical properties to that of even the toughest thermosetting rubber. Being thermoplastic makes it recyclable unlike the typical thermosetting rubber equivalent cables.

PUR is not suitable as an electrical insulation material but has some outstanding properties as a cable sheathing, making it suitable for high performance electrical cables in the most challenging of environments. It is very flexible throughout a broad temperature range, typically between -40°C and +125°C.

PUR sheathing is extremely wear-resistant and mechanically tough – it’s very difficult to cut or tear. It also has excellent ageing resistance against environmental humidity, ozone, UV radiation and microbes whilst offering an excellent barrier to a wide range of chemicals and oils. A useful characteristic of PUR as a sheathing material is its anti-kink property, making it ideal for flexible and retractable cables.
