A drag chain is a device that binds cables or wires or air and oil pressure pipes to facilitate their rotation and movement. The material of the drag chain is generally reinforced nylon, with high pressure and tensile load, good toughness, high elasticity, and wear resistance. It is flame retardant, and has stable performance at high and low temperatures. It can be used outdoors. Resistance: Oil and salt resistant, with a certain degree of acid and alkali resistance.
