Plastic towline in accordance with the structure can be divided into i bridge plastic towline closed plastic towline; divided into small towline, general type Tuolian with large towline in accordance with the model, in accordance with the noise figure can be divided into ordinary towline and mute towline; Hebei Cangzhou nylon plastics the towline factory price can be divided in accordance with the form of ordinary towline, the towline in parallel, S-type towline; raw materials into the original package of plastic and recycled plastic. 
 Common types of plastic plastic towline towline model is generally based on the internal height and internal width to determine, because they are not standard products, the outer size of the factory are inconsistent. 
 Plastic towline model 7 * 7,10 * 10,10 * 15,15 * 15,15 * 20,15 * 35,15 * 40,15 * 40,15 * 50,18 * 18,18 * 25 18 * 35,18 * 50,18 * 60,25 * 25, 25A * 38,25 * 57,25 * 77,25 * 103,35 * 50,35 * 60,35 * 75,35 * 100,35 * 125,35 * 150,35 * 175,35 * 200,45 * 50,45 * 60.45 * 75,45 * 100,45 * 125,45 * 150,45 * 200,56 * 95,56 * 125, 56 * 175,56 * 200,56 * 300 There 62,65,80 series and other towline. 
 Nylon 
 (1) material: reinforced nylon, with high pressure and tensile load, good toughness, high elasticity and abrasion resistance, flame retardant, high and low, stable performance, can be used in outdoor, nylon content determines how much drag the use of strength and wear resistance of the chain, as well as the size of the noise up and running. 
 (2) resistance to: oil, salt, and a certain acid, alkali capacity. (3) speed and acceleration (specific speed, acceleration, depending on the operation may be). 
 (4) operational life. (1) the structure of plastic towline towline shape like tanks chain consists of a large number of unit link, the link between rotate freely. 
 (2) the towline of the same series within and outside the same pitch, inside width towline, the bending radius R may have a different choice. 
 (3) unit chain around the chain plate and the upper and lower lid, to towline each section can open, easy assembly and disassembly, do not have threading, open the cover to the cable, tubing, trachea, plumbing in drag chain. 
 (4) Also available separate pieces, separated by chain space as needed.
