With the continuous innovation of production technology of high flexibility towing chain cable, the appearance of various new materials is also improving the performance of high flexibility towing chain cable, promoting the variety of cable from single to multiple, in order to meet the needs of more working environments. Sheath is an indispensable part of traction chain cable, the choice of its material has a great impact on the use of cable, PVC and PUR are commonly used in the market traction chain cable outer sheath materials. So what's the difference between these two materials? What's the difference in use?

High flexibility drag chain cable
First of all, from the point of view of price, PVC jacket is cheaper than Poole jacket. Because PVC (polyvinyl chloride) material although has good physical properties, but poor photothermal stability, in some special use environment, such as long exposure time or high overheating temperature, easy to decompose, therefore, affect the service life of high flexible traction chain cable. Polyurethane is a rubber between PVC and rubber elastomer, so the stability of the material is relatively good.
Secondly, the application scenarios are different. Although both materials can be used as sheaths for streamers, PVC is well adapted to humid environments due to its response to light and heat, but should not be used indoors for extended periods of time. PUR not only has the excellent characteristics of PVC, but also has strong tensile strength and wear resistance. Oil resistance, moisture resistance and corrosion resistance greatly increase its application range.
