Choose cost-effective PVC instead of PUR
As a jacket material, PUR (polyurethane) has decisive advantages in some areas, but not in all. Our goal is to enable you to objectively decide whether a cable with a PVC jacket is not only sufficient but also perhaps the better solution.Contents:

Advantages and properties of the two materials
PVC
- Good abrasion resistance
- Highly flame-retardant
- Very easy to harness
PVC or polyvinyl chloride is a versatile plastic mixture. Nevertheless, there is a widespread notion that PVC cables are suited to static installation only.
But that isn't quite right. There are thousands of different PVC mixtures for a large number of different applications, so it is important to find the right one for use in energy chains. For igus chainflex cables, we have selected a mixture that shows great abrasion resistance in e-chains, can be very easily harnessed, and is even cost-effective. That is why PVC cables are often used in industries in which dry environments and room-temperature conditions are common, such as the packaging and wood industries.
PUR
- Good oil resistance
- Durability at low temperatures
A PUR (polyurethane) outer jacket is primarily notable for its very good resistance to oil. PUR cables are often used in industries such as machine tool manufacturing, in which environmental conditions are often dirty and substances such as oil or coolants are common. Still, the jacket remains flexible even in continuous operation in an energy chain and can withstand high mechanical loads. Furthermore, PUR cables are also well-suited for low-temperature applications.

Practical chainflex application examples
Today, servo cables are the standard for drive technology in automation and machine construction. The movements which cables are subjected to in these industries are associated with great mechanical stress. Furthermore, cables are often used in environments where moisture, oil, dust or swarf is common. That is why choosing the right jacket material is critical. To ensure constant jacket material quality, our cables are tested time and again under real-world conditions so that a binding guarantee can be granted or the service life calculated online. The cables are tested in both short-term batch tests and long-term service life tests.Example of long-term test 3841a on a CF21 series servo cable (PVC jacket) with a test bend factor of only 6.1xd and 54 million strokes completed.

But this choice of jacket quality is available not only for our servo cables, but also for all our other cable types, such as measuring system cables, bus cables, control cables etc. They, too, have been tested in our test laboratory.
