Plastic towline models are mainly internal height and width determine the towline internal model, can also be based outside the high and wide outside to set. Plastic towline models have 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 * 25,25 * 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 towline. Divided by the original package of plastic raw materials and recycled plastic, nylon towline content determines how much strength and abrasion resistance as well as the use of running noise size. Nylon content ranging from 5% -17%, but over, but 19%. Plastic towline structure (1) towline shape like tanks chain composed by a large number of unit links, link between the rotating freely. (2) within the same series towline high, outside the high, the same pitch, towline in width, bend radius R may have a different choice. (3) unit chain around the chain plate and the bottom plate composed towline can open each section, easy assembly and disassembly without threading, open the cover to the cable, tubing, pipe, pipe, etc. into the towline . (4) Also provide separate pieces, the chain separated by space as needed. Plastic towline basic parameters (1) Material: reinforced nylon, with high pressure and tensile load, good toughness, high elasticity and abrasion resistance, flame retardant, high temperature stable performance, can be used outdoors. (2) resistance to: oil, salt, and a certain amount of acid, alkali capacity. (3) the speed and acceleration (specific speed, acceleration, as the case may be running). (4) operating life.
