Currently, most of the highly flexible drag chain cables on the market are made of PVC, PUR, and other outer sheath materials. Many customers do not understand the advantages and disadvantages of these two insulating sheath materials. So, how do you choose a suitable, highly flexible drag chain cable?
First of all, in terms of price, PVC drag chain cables are cheaper than PUR drag chain cables. Although PVC material has good physical properties, it has poor stability to light and heat. It is easy to decompose in some particular use conditions, such as long-term outdoor exposure or overheating temperatures, affecting the use of highly flexible drag chain cables. Life. At this time, it is necessary to use PUR drag chain cables with better weather resistance and UV resistance.
Secondly, the actual usage conditions are different. PVC drag chain cables have medium resistance to oil and coolant and can be used in humid environments but not outdoors. PUR drag chain cables are tear- and wear-resistant and have excellent oil, hydrolysis, and corrosion resistance. They can be used in humid environments and are suitable for indoor and outdoor use. PUR's performance is superior to that of PVC in all aspects
.
To sum up, the cost of PVC drag chain cables is relatively low and can be used under most working conditions. It has excellent cost performance. After all, extremely harsh working conditions are rare. The PVC highly flexible drag chain cable produced by Acewo Cable can meet the requirement of 12 million reciprocating movements without interruption and has obtained TÜV Rheinland robot cable certification.
PUR drag chain cables have good elasticity, excellent mechanical, oil, and wear resistance, and can maintain excellent mechanical resistance in low-temperature environments. Therefore, they can be used under the same conditions (drag chain bending radius, speed, acceleration, stroke, temperature and humidity). ), the service life of the PUR drag chain cable is longer than that of the PVC drag chain cable. If your equipment's drag chain has fast speed, long stroke, high frequency, small bending radius, oily environment, etc., it is recommended that you choose PUR drag chain cable.
Therefore, choosing which sheath cable material is necessary based on actual use requirements and cost. The drag chain cable that suits you is the one you should choose!
