● What’s the difference between PUR and PVC cables?

A PUR cable is a flexible, silicone, and halogen-free cable with PUR outer sheath polypropylene conductor insulation. It is oil and flame resistant and can be used in drag chain applications with minimal bend radius.

● PVC better then PUR cable?

Well there are two valid replies to this question. The first is cost. PVC cable is a lower cost compared to PUR cable, as a rule of thumb PUR cable is around 10% to 20% more for a similar specification of cable, so if you don’t need to use PUR then there is no benefit!

From a technical point of view however, it depends on the application. If you have a wet environment then PVC tends to be the most suitable cable as it has good resistance to water and is therefore the preferred cable for food-processing applications. In machining applications PUR becomes the cable to use owing to its better resistance to cutting and hydraulic oils. There is another downside to PUR with regards to installation – it is harder to strip – so if you don't need to use it, PVC is always the better choice.
