What is the difference between highly flexible PVC drag chain cable and PUR drag chain cable, TPE drag chain cable?

Currently on the market of highly flexible cables, the outer material is generally to PVC, PUR, TPE and other materials, so we put these materials of flexible cables were called: PVC flexible cables, PUR flexible cables, TPE flexible cables. PVC flexible cables are used in the drag chain system of highly flexible PVC sheathed cables, the use of special highly flexible PVC to do the outer sheath, medium resistance to oil and coolant, can be used in wet environments, but can not be used outdoors. PVC flexible cable is a high flexible PVC sheathed cable for drag chain system, using special high flexible PVC as outer sheath, medium resistance to oil and coolant, can be used in humid environment, but can not be used for outdoor, PUR flexible cable is used for drag chain system, using PUR as outer sheathed, it is tear resistant and wear resistant, it is excellent oil resistance, hydrolysis resistance, chemical corrosion resistance, it can be used in humid environment, it is suitable for both indoor and outdoor, and it has good weathering performance, low temperature resistance up to -30°C. And the mechanical properties of PUR flexible cable are very good. And PUR flexible cable mechanical properties than PVC flexible cable is much better, PUR flexible cable wear-resistant, high mechanical strength bearing capacity, impact resistance and shock absorption performance is outstanding. And PUR flexible cable weathering performance is also much better than PVC flexible cable: oil resistance, low temperature resistance, hydrolysis resistance (polyether type); toughness and elasticity: PUR is between PVC and rubber elastomer rubber, so the toughness and elasticity is also better than the PVC flexible cable.TPE flexible cable is a kind of flexible cable than the PUR flexible cable in the weathering, ozone and ultraviolet light resistance and use of a better range of temperature Flexible cable, suitable for indoor and outdoor, can be completely and plants, animals or synthetic organic fat, grease paraffin and related latex liquid contact. Good resistance to ammonia compounds and biological gases, cold and hot water and water-soluble detergents; resistant to temperatures as low as -40°C.
