The main components of the plastic drag chain are the upper and lower cover plates and the left and right chain plates. Each part of the drag chain can be opened, which can be easily installed/removed without threads. Opening the cover is enough to put air pipes, cables, oil pipes, water pipes, etc. into the drag chain.

The main material of plastic drag chain is reinforced nylon, because it has high pressure and tensile load, good toughness, high elasticity and wear resistance, flame retardancy, stability at high and low temperatures, and can be used outdoors. The amount of nylon determines the strength and wear resistance of drag chain and the noise level during operation. Nylon content is 5% - 17%, but not more than 19%. Generally, the content is about 30%.
